Stupidly drove over a ramp thing and then brakes started going spongy. After parking there was a small puddle and when I pressed the pedal with engine running there was a hissing/whoosh from under left rear wheel where puddle was. Clearly brake pipe leaking

how easy is this to fix.

I am not having much luck wih my beloved GV

 

Either buy the brake pipe flaring tools, pipes, nuts, etc., or get garage to do it.
There was someone on here months ago trying to ascertain the thread on the nuts. Could go to Chrysler garage and order nuts to suit your car and that's that bit sorted.
Use these copper pipes.
Try You Tube are to this job, you never know might be done on a Voyager.

 

Is there not way soldering or repairing it lol

 

Wow....Maybe brazing....but might be illegal now...Possible repair tube job with inline connector, flaring ends. But garage would want to do whole pipe quoting regulations.
Not many pipe jobs on here, like, I've read one.
Got to know what your doing incase of leaks.

 

@ 3000 psi don't even think about it. Buy a bit of 3/16 pipe at a quid a foot and a couple of 10mm unions then borrow a flaring kit. Just take it to a local indie and ask how much !

 

Usually with soft metal, brass etc., the threads are "gas" or plumbing threads. Hope this helps.
If you do repair the pipe (risky), test it well by putting as much force as you can on the brake pedal several times -- and again later. Personally, I'd go for new, and fit it by the book.
