brakes Stripped Brake Master

[johninsf]

Hi all,

 

Trying to replace the brake master which has been leaking into the brake booster.  Using a flare wrench the first 3 lines came off with no problem, one was tight but still loosened farily easily, seemed like this was going to be an easy job.  The line connected to the hex nut (runs to the poportioning valve I think) was/is completely stripped.  What are my options here, vice grips, cut the line and run a new one (no idea how difficult/possible this might be), other ideas??

 

Thanks!

You say the line is stripped. What does that mean? Is the hex shape of the nut ruined? Is the thread stripped? Is the flair stripped off the tubing? Please explain.

Vice grips.  Put them on plenty tight the first time, so they don't move and chew the nut up worse.

 

If you're lucky, it's one of the 4 lines running to the front calipers. 

If you're really lucky, it goes to the left front- those are easy to replace.

The right side is harder, but not too bad.

 

If you're unlucky, it's the one going to the back.

That takes quite a bit of work.

TobyB, I was unlucky in your scenario.. I stripped the flare nut to the circuit going to the rears, and replaced the line. That really tested my patience last year.

they are all pretty easy to fix.  cut the line in an easy to reach place, put a flare nut on it, get a male to male adapter at auto parts store and get a new premade piece of hard line in the length you need at the same auto parts store to replace the damage piece.  bolt together, bleed brakes, go.

Thanks for the replies.  It's the odd line that comes off the end of the bottom of the master.  I think it runs to the porportioning valve.  I wondered if it is possible to cut and patch, thanks for the tip mlytle.

that is the line to the rear brakes. yes, you can cut and patch it.    there may be even enough slack to cut the flare off, slide the stripped nut off, put  new nut on, and reflare the end.

Marshall, you're better than I am.

 

I've NEVER had much luck making bubble flares.

 

Just lack of talent, I suspect.
