brake line fitting
 

Busted the line at the fitting on the rear passenger side today. I can't get the fitting off, it seems really soft on both ends. Box wrench and socket wanted to round the edges with the slightest amount of torque. Special tool of tricks?

Orielly didn't know the diameter of.the line either. My chiltons didn't have specs that I seen. I assumed its 3/16.

93 f 250

what kind of ball bearings does it take?

Have you tried heating the fitting with a torch?

Not yet since I can't break it loose from the split either.

Hit it with a wire brush, soak with PB blaster, let it sit for 30 min, wipe it clean and try again. If not, Vice grips, drill, and tap & die set may be your only option here

Check the fetzer valve.

Vice grips

not going to work.too big.

Thought you were linking to thosesquare drive sockets.

Wife bought me a set and they work great

i'm assuming this is drum brake and the line is alloy. I'd use reg pliers and I know it'll get buggered up, but I doubt you have a choice. If it comes off, great -- you can likely get it back together with pliers and it doesn't take a lot of torque to cinch those.

But, if not...

If you can replace the line at the coupling easy enough, just cut it and crimp the end shut so a minimal amount of fluid is lost. you're gonna need to bleed that thoroughly after you're finished, either way. you'll need a new slave unit, they are cheap enough.

Can I just splice the line and bypass having to **** with the coupling?

I don't know of any way to do this. The flair fitting is done by machine and it has to be precise.

There is a wrench just for brake line fittings so the edges won't strip. Ask auto parts store

I use these in plumbing, but I don't see why it wouldn't work here

brake lines are made to be broken.

Eh. Brakes have a LOT of pressure on them. Would not try.

I've got a line flare press, they're not expensive or hard to use. It wouldn't surprise me if O'Reilly's has one for rent.

Tough situation MO, about the only way I've gotten out of it is to either soak the fitting with some good penetrating oil then work it back and forth with a wrench while continuing to hose it down with the penetrating oil, or like you mentioned cut it out and splice around it.

Have you tried fuel line wrenches?

I know you can't do a goddamn thing with a fuel line without it.

If it were me, I'd get a small pair of channel lock pliers, **** it up getting it loose and replace the fitting when it goes back together.

Besides, there's special compression fittings just for brake lines, no sense in trying to make a plumbing fitting work.

year make and model need more info and i can help you

They sell brass compression fitting for brake lines. I use them sometimes.

Or rent oreilly's flaring tool.

Or pinch that ****er off and drive up here and I'll fix it

well then send it to him :D He's going to want to use it with the line connected in place, so I hope the damn thing is small enough to use under the vehicle.

or... ya. **** brakes. especially drums:#

Dude don't come at me like that. Especially after your post saying a flaring press couldn't fit under his truck.


Guarandamtee mo could drove that truck to me with one brake lone pinched off to the rear.


I wouldn't recommend it on the front though

My flaring tool , that will do up to 1/2" line, is hand held

This, although they are technically just generally called "line" wrenches, as they work for specifically brake and fuel lines due to the nature of the fitting.

Don't **** with brake lines without the proper tools. Probably the one area where the Risk really isn't worth the reward, and 9 times out of 10 it leads to a massive headache.

PB Blaster and/or a torch?

If you cant get it off, say **** it and clip the line. A new brake cylinder is ten bucks. Thats what the brake line is screwing into. You can buy a new length of brake line for 10-15 doll hairs. Rent the flair tool and buy a mini pipe cutter. Easy as pie. The flair tool tells you when to stop. Also do not let the master go dry. I have a feeling you know but you never know who is reading this.

I'd strongly advise against doing this unless you've done it before. Snipping brake lines and redoing a line is extremely dangerous as the length and diameters of these lines are precisely measured and crafted.

Not true. Done it a couple times.

Um, what is not true?

The only statement of fact in there is that they are precisely measured and crafted. If you are so much as 1/16th of an inch off on making your own brake lines, your brake balance will be off, period, guaranteed, end of story.

You also said you have done it a couple times, which was the qualifier in my statement that if you hadn't, you probably shouldn't.

I'd be willing to bet this is a farm truck. I dont think the length matters. The flare tool is a die that makes accurate flares. I think MO is experienced enough with tools to not **** it up. I see where you are coming from and given the fact that i am just a shade tree mechanic you could be right but brake lines are a common fix. Especially on the drums. I think rear brakes supply around 20% of the braking power.

I am an ASE certified mechanic, brake lines are not a common fix, and I assure you that they are length specific on every application with any form of pressurized fluid braking system.

lol

Maybe so but... I'm no mechanic and I've cut out a few brake lines and used those fittings to splice in a new section. This was just for small cars though, but it worked fine.

I have fixed probably over five hundred brake lines, I can guarantee a sixteenth of an inch on an eight foot section of isn't hurting a thing.

Dude is crazy.

But, he's ASE certified!

Don't believe everything you read.

ROFL They cant put anything on the internet if it isn't true

Damn really? Learn something every day

I'm not saying you can't use the fittings, I'm saying don't do it if you don't know what you are doing. If you know what you are doing, by all means, have at it.

Wow, a whole 500 brake lines? You must be the best in the business.

Tell me, oh great one, what happens when one brake line is shorter than the other?

Care to see my certs?:spock:

Have you ever even worked for a dealership and gone through any form of training? Or are you one of those shadetree "I have a garage" types who opened up a "shop" to run a sidejob repair business out of?

shit just got real

Turn the middle side topwise...topwise!

I bet all of his tools say Husky or Stanley ROFL

I run Quaker State in my brake lines.

Don't worry, Jasonsauto will tell you that you have nothing to worry about.:spock:

:popcorn:

to be honest, however, Jasonsauto did do an outstanding job on replacing the fetzer valve on my VW Rabbit. I was very happy with the service and price.

I'd recommend him

Every rear differential on a truck has brake lines that are longer to the right than to the left.


Every ****ing one.

Actually I have been to school, been lead tech, been ase master certified, own an actual repair facility, have techs that work for me, turn a pretty good amount of work out of my shop on a daily basis. I averaged right around eighteen tickets a day this last year, with an average of just over a hundred dollars a ticket.

How about you?

Yeah...

:spock:

I just like how I stated that 1/16th of an inch will mess up the brake balance, which is a cold hard fact, and he's like "it won't do anything".

Ummmmm.

And there was a guy around here sometimes dinny blues that can vouch for just about everything I have said. He's been there multiple times.

Oh and if you see this Dinny I haven't seen you since I saw her but the Benz is ****ing nice

Its going down like Fraser and I'm not talking about Kelsey Gramer! :popcorn:

Let me ask you a question Mr. Ase Master Certified

Do you know why that is?

Also which tests did you choose and pass for your master cert? What did you score?

18 tickets a day at just over a hundred dollars a ticket is ****ing sad.

You probably do.

Yeah it won't. You are ****ing crazy, just because you read it somewhere doesn't make it true.

Not in length at least. Diameter will,

Answer my question smarty pants.

What happens when you cut a brake line on a vehicle 1/16th of an inch short of its length when it rolled off the showroom floor?

Yeah, it will. And you are not and have never been a certified master tech if you say so.

Unless you're like 85 and were around before Master Techs became uniform industry standards.ROFL

is this going to effect my fetzer valve warranty?
I'm getting a little concerned about your lack of detail.

lol I live in a town that has 2100 residents. And 19000 in county.

And I own over a hundred thousand in hand tools, not counting my alignment machine, lifts, compressor etc.


Also there are ten other shops in town.

I do ok.
Posted via Mobile Device

...well, ok. But can you install mufflers?

....I didn't think so.

Did your paper work say "fetzer" or "ferntzer"? You could be screwed!

So you're a mom and pop shop that hangs an "ASE Certified" sign in front of your door because you bought it off of Craigslist while you were in town?

Sounds like half the shops in Merriam and Olathe to me.

A Certified Master Tech would never tell me that 1/16th of an inch on a brake line of all things "doesn't matter".ROFL

He's X1 certified, I saw the sticker plastered on his Chiltons books.

Nothing. I don't know how you make brake lines but it would be literally impossible to bend the line and make it that close by hand.

I see you haven't done it much or you would know

Man brah, is you mad? You are hating like a city cop!

Actually that is the only thing I don't do...

:spock: I made brake lines for a solid three months @ Pitt State Auto Tech, do you know what our ASE Certified Master Tech told us and taught us?

shit!
damn you 'Sauto!

last time I come to your 'shop'....or whatever you call it.

:clap:
I should've chosen something else like battery installation.




...wait. Yeah, you probably don't do that shit either. Hack.

But 1/16" is making a big difference on a line that could be 8 feet long...

And no brake lines are different lengths.


ok guy... What about thepickups that the passenger side line runs into the drivers side line in the drivers wheel well then runs over?

Wouldn't that be pretty unbalanced?
Posted via Mobile Device

Ok all you smarty pants. The length of the stupid line will not matter. Period. As long as it has fluid in the line it could be 5 miles long it will still move the same amount of fluid. Hydraulics 101 boys.

but like the last post said. Diameter is the one that has to be the same/

A little.

I Love when these backwoods shadetree mechanics that spent zero time actually testing, at school, and being paid by your employer for training, tell me that something "Doesn't matter", all because they did work on a farm truck that sees 500 miles of road and 1500 miles of fields annualy, and didn't have an issue.

Meanwhile I'm over here on fleet vehicles hitting 20-30k a year on the road where there are other vehicles.

I paid my dues, got my certs, went through training, and actually have the mental capacity to understand 'why" and "where" which is why I am a Specialist, and he tells me I'm wrong.

Its my job to be right dude.

:popcorn:

Brother is going ham tonight!

But everything you said about me and this issue is wrong...

Be mad

thanks. I don't think this guy has been right about any post he has on the planet
Posted via Mobile Device

I'm dying to hear this because the brake lines just transmit pressure and if they are bled properly there will not be any difference in pressure for lines 1/16" difference in length.

Once more, in English please.

So you're telling me that in a system that is not 100% continuously pressurized with fluid, that the length of a brake line does not matter. I won't disagree on diameter at all, but length you are wrong.

What happens? For those that want to know. The shorter the distance from the master cylinder to the caliper, the sooner braking force will be applied on that caliper. What happens when one side of the car brakes before the other? It pulls. Is pulling a good thing? Apparently according to Jason.

I've had this type of discussion with guys that just got out of school before. Work in the real work for awhile and you will learn.

I understand what they are going to teach in school, but is not always real world applicable.
