just be glad he didn't go to DeVry.....you'd really be hearing about expertise

Do it right or don't do it at all.

Word.

I'm not mad, but I'm not wrong either. I'm 100% by the book. I don't cut corners and have a full working knowledge of 99% of everything used in automobiles on the market today.

Really? You couldn't even answer my question.

It is always real world applicable to do things right......

I'm also not fresh out of school either, I've got a decade under my belt as a mechanic, and worked for 2 different dealerships and was co-owner of my own shop until January of this last year.

Safe to say I know a thing or two buddy.ROFL

Right?

I agree with this 110%

Is this true for a compressible fluid or an incomprehensible fluid?

Fluid doesn't compress. If there is no air in the system as soon as fluid moves anywhere it moves everywhere.

Restricted lines or hoses cause pulls.


Again, what about a pickup that the line comes from the master to the lf wheel well and the rf line tires into it there and runs all the way to the Rf wheel? Why doesn't the truck pull left?


You are wrong.

He just sidestepped the fact that my analysis was right, and basically admitted he was wrong, and you're agreeing with him.

I've heard it all now.

true; but I used to work with Engineers who think that because 'the book' says X....then X it is, without taking into consideration what actually happens/needs to happen in the field.

It's great you've got our certs *not being sarcastic, it's great*, but there is a dynamic between education and experience ; and how they work together.

Hope I'm not coming off as a dick; I'm not meaning to etc.

NM..I just saw your post about your experience. I thought you were just out of school.

You do realize that brake fluid is non-compressible no?

If you're going to test me on my knowledge, take 5 seconds or 5 hours or however long it takes you to do so, and actually write me a descriptive, intelligible question so that I can answer it.

I am not wrong, braking in just about 90% of the light trucks and cars on the road today is not 100% pressurized and contained, and thus the length of the brake lines from master cylinder to caliper are incredibly important.

I don't see myself saying you are right anywhere, in fact I asked why a manufactured vehicle would do the exact opposite of what you are saying
Posted via Mobile Device

probably a reason you no longer own a shop. And it's not your expertise...
Posted via Mobile Device

its all good

I take it you have zero working knowledge of the braking system in most cars on the road?:spock:
They aren't doing the exact opposite of what I'm saying you..........I give up arguing with unintelligible backwoods rednecks.

whayyyy ooooooooooo / McMahon

I'm not sure what to make of this guy.

Or because we both did it to stay employed and finish our certs while keeping experience on our resume so that we could both jump straight into Ford that Spring?


No, couldn't be it at all.

I have you a hypothetical. I know you won't address it because two major manufacturers built their trucks in the 2000s that exact way. just do you know I'm not just working on "farm trucks"
Posted via Mobile Device

You can't even spell properly, and yet you're trying to make a rebuttal.

Really?

Take 5 minutes to write your question in a descriptive manner, and I will answer it.

I was just trying to lighten the mood. Jason knows a lot about cars, calling him a shade tree mechanic is ridiculous. You guys should agree to disagree.

Yes they are.

The lines tee, actually the sorter line is a straight dot from the steel to the hose and goesDIRECTLY to the lf wheel. The rf steel screws in at a ninety to the steel from the master and them Goss ALL THE WAY TO THE RF. Why doesn't it pull left? by your incorrect theory the fluid should get to the lf quite a bit earlier. But it doesn't.


Obviously you haven't worked on many vehicles or you would know exactly the vehicles in talking about

lol now playing spell check to deflect huh?

Good move.

I'm sorry..I don't speak Spanish / Burgandy

He could just Agree that I'm right, because I am.

Oh my god dude, seriously? 1. You aren't even defining the make and model of the vehicle you are arguing about, yes it matters. 2. You aren't telling me what braking system is on said vehicle, yes it matters. 3. I can barely understand your backwoods English, fix that.

Don't ****ing argue with me about something as basic as this, if you aren't going to tell me WHAT THE **** YOU ARE ARGUING ABOUT IN THE FIRST PLACE.


Simply put, in a braking system where there is not always 100% pressure, the length of the brake line indeed matters, because of how the braking system is designed to exert pressure into the system to apply braking pressure.

Herpty derp.

I don't mind arguing with idiots, when I can read what they are saying.

Also, and correct me if I'm wrong here Jason because it is hard to understand you, but are you referencing a Proportioning Valve there?

I'm seriously lost otherwise.

I'm no mechanic but, I'd say that if line a is 4' and line b is 5', as long as both lines are filled with fluid, once you apply the pedal, the pressure should be the same at the end of both lines. But what do I know...

fetzer. the FETZER valve.

ROFL

You would be correct.

However, as I've explained and reiterated to the point of beating a dead horse here, that does not apply in a system that does not have a constant, continuous pressure.

Do you know what system in your car follows that lack of constant continuous pressure? You guessed it, your braking system!

Again thanks. This guy doesn't get it.
Posted via Mobile Device

Apparently you don't get it ROFL

there is constantly fluid taking up the space in the lines. once pressure is applied it hits both ends simultaneously
Posted via Mobile Device

Oh my god, I"m done arguing with you now. Go to school.

Bye.

Well I work in the real world. I'm not talking about a proportioning valve. IF YOU worked in the real world you would know exactly what vehicles I'm talking about. But you most obviously don't. There were only millions made.
Posted via Mobile Device

Lol. Figures
Posted via Mobile Device

figures you don't do mufflers.


....likely story.

I do work in the real world, and I've got no idea what you are referring to, let alone being able to discern the make or model of the vehicle from your gibberish.

You are stupid. You are not a certified master tech, you are a liar.

You cannot be as idiotic as you are, and pass the certified master tech program, I know this, as I have gone through many ASE programs.

You can't even tell me which tests you passed and what your "route" was through the program, just that you are "ASE MASTER TECH CERTIFIED".

Yet you challenge my knowledge on the matter.

Let me ask you a question smarty pants, why do we have bleeders on brake calipers if it is always 100% continuously pressurized?

air bubbles bitches!

BOOM!!!!

And how do we get air bubbles?:D

Oh Jesus ****ing Christ.


I'm done. Out. I can't believe you are even asking that. You have got to be a ****ing troll
Posted via Mobile Device

A car should go forever with out bubbles in the lines. Theoretically forever.
Posted via Mobile Device

Of course you are done and out, you can't even tell me what the names of the tests you took on your way to your "master" certification.

I am not a master certified tech.

I did however, past my L1, L2, and go through A1-A9 tests and received certs.

Do you even know what that means without using google?

:shake:
You are so stupid ROFL

....air?

http://content9.flixster.com/questio...417327_std.jpg

Good!

And how do air bubbles get into a "100% completely pressurized system" according to Mr. Jason guy?

Who ever has to get their brakes bled if the system isn't opened?


Can we get a show of hands of people who are getting their brakes bled for scheduled maintenance?

If you are someone is ****ing you
Posted via Mobile Device

Now some scheduled maintenance now is to flush the fluid, but just due to break down.
Posted via Mobile Device

well shit....I don't know man.:D


...ask me something else. If it's related to poop, porn, or beer, I'll probably have a good shot at it.

It's a sealed system. Sealed, pressure doesn't matter.
Posted via Mobile Device

Now I know you don't work for a big time shop or dealership :clap:

I wonder, what is "due to break down" covering?
It was a trick question. There isn't a braking system in any automobile that uses a non compressible fluid that is 100% pressurized, sealed, and without failure.

Because of this, we have bleeders on every caliper, because at any point between the master cylinder to the prop valve, and prop valve to the caliper, there is a chance for contamination of the system.

It would be foolish to think for a second that the braking system in a car is completely contained and is only understood by pascal's law.

ROFLROFLROFLROFLROFLROFLROFLROFLROFLROFLROFLROFL

If you are getting air in your brake lines the compressability of the air will completely overwhelm the compressibility of the brake fluid. Exoter, how do you manage to keep the exact amount of air in each brake line so you don't get any pulling?

I don't trust anything you say anymore after your Fetzer valve replacement.

it's out of spec, and voided my warranty.

where the **** is Fax, and Rainman when you need them.

lazy bastards. they could solve this shit in 4 posts.

:spock:

What?

Its like you intelligently put together a question that under the guise of intelligence, is rather unintelligent.

To answer, you don't want air in your brake lines, ever. There is no way to create an exact amount, nor would an exact amount manage to "level" braking pressure enough to completely dissuade the chance of a "pull" due to the finite relationship of the length, diameter, and components of the braking system being built under the understanding of implied fluids.

Also, if there is air in your system, you have a leak. And if there is a leak, it is impossible to "contain" a finite amount of air pressure inside of the braking system as the basic design of the braking system allows air to be pulled in rather than pushed out, and your brake fluid in turn is the odd man out of the equation.


I'm still wondering what tests dummy dums has taken, what route he took to get his master tech cert, how he thinks brakes systems are designed, in theory, to function forever, and so forth.

Should have let this dude do it
Posted via Mobile Device

typical small town mechanic

The fluid breaks down. Heat breaks it down.

If you never had a leak you would never have to bleed it, so IN THEORY the brake system would last forever. In theory, but not in the real world, where I work
Posted via Mobile Device

I don't really work with Fetzer stuff, I'm not radio shack.

Fetzer is German. I should've made that clear. i have a VW

Well no shit fluid breaks down smarty pants, but we're talking about the braking system, not part of it, or the force that drives pressure, which isn't actually the fluid itself.

If you were right, we wouldn't have service calls on rubber brake lines. If you were right, we wouldn't have expansion issues in rubber brake lines due to over pressurization in the braking system.

How does over pressurization even happen?

If pressure doesn't matter, how can you create a seal under zero pressure?:spock:

If I'm not mistaken, Fetzer has to do with something in the booster circuit/amplification world, but I could be heinously wrong. I've worked on a lot of Audi/VW stuff in my day and own many specialty tools (of which there are many for VW/Audi) and I've never ran into a Fetzer problem. Of course, if VW/Audi uses some kind of mosfet/fetzer system in their audio systems, then perhaps I have and didn't know.

As of right now, I do not know, but I"m pretty sure this is an attempted troll maybe?

90 percent of the time that rubber brake line got RESTRICTED. that's why they fail.

That's why when you step on the brakes the car pulls.one way then straightens itself out, then drifts the other when letting off the pedal. The restriction slows the fluid to the wheel, then holds the fluid at the wheel longer.
Posted via Mobile Device

I think you're right. that sounds about right.
VW use inverted threads on their head bolts too. ****ing Germans

ROFL

Mo .. go to a salvage .. if ya wanta repair it cheap .. line should be teed at middle of rearend .. take it loose there and then pull wheel cylinder too .. replace it all fo few bucks .....

for the record......I'm so glad you guys know WTF you're talking about lol. If I tried to do it myself, I'd probably die.
lol

I'd have better luck disarming a nuclear bomb than working on brakes, from the sounds of it

well said.

actually it's teed on the drivers side of the diff.


OMG the line he needs is longer with no prop valve in between them.

Lol at the prop valve talk. School boy

'Sauto, your expertise is beyond my knowledge...

but if you need me to....I'll cut a bitch.
That's about all I can offer.




.....seriously though.......I have a knife.

It was an intentionally silly question to illustrate the ridiculousness of a difference in 1/16 of an inch in brake line length. My point is that if you have ANY air in the system it will completely obliterate any effect of difference in brake line length because air is more than 1000 times more compressible than brake fluid. If there was any measurable pull due to a 1/16 of an inch difference in brake line length, you would end up in the ditch if you applied the brakes with air in the line.

if you need to know how sharp it is, look up my thread where I cut off my huge skin tag with it.



....so yeah.......it's pretty awesome. It could probably cut a brake line if you know what i mean.....*wink wink, nudge nudge*

Most of the time air won't cause a pull.
just a spongy pedal

You're gonna die man!

you ****ers are really making me start to question the status of my brake lines

thanks for the paranoia.
bastages (especally you 'Sauto)

I'm going to bed ...after playing NBA2k13...

but If I die tomorrow because brake issue bullshit, I'm logging in tomorrow and blaming everyone.

and I fully expect a 'well-bye' thread. but not with that pussy Powers Boothe....but Fisty McTatt.

I'll check tomorrow to see if I need to adjust the ft lbs of torque on my fetzer valve....since, obviously 'Sauto ****e it up earlier. I don't recommend him for the record.

90%? No, not even remotely lol.

You should see my bag of "Jetta" stuff that I tote around in the car with me if I end up getting called in on a VW hehe.

Um, are you under the impression that all brake lines are equal, or that I've said that? Or that I've said they have to be equal?

You've never driven a car with a serious brake line fault have you? lol.

The point isn't that 1/16th of an inch can matter abstractly, its that when you REMOVE 1/16th of an inch, it will matter.

You are half right, half wrong because you didn't specify where the air was.

If you had actually taken an ASE test, you'd know the tests are quite descriptive and specific.

Take a quick peek at those hoses. Check for cracks and lumps.

If your car is more than five years old it's a good idea to check if the steel is rusting. How bad.


I replaced two steel lines and an abs motor on a 2006 silverado today. LOL
