Good morning,

have a leak on one of my rear brake pipes.  It looks like a long one, from front to back, that ends at the flexi hose. Does anyone have a diagram of the brake lines  as I am having difficulty in seeing the route it takes (it looks like part of the exhaust and heat shield needs to come off to get to it  )

I can find the caliper brake line and flexi hose on the net but not a long one.  Are they available or would it have to be made?

cheers

Roland

Spooky, discovered yesterday on the 2.2 LPG that brake pipe is leaking on the pipe from union to rear caliper.

That is one section that can be replaced, but on the long section from the front, it's generally advised to just replace a section, rather than the whole pipe.

Find the offending section, but it out and join a new section in

Hi Tunnie,

Doh! Why didn't I think of that!  would make for an easier/quicker job.  Sometimes you need someone to point out the obvious 

All I need to do now is get the parts 


Thanks

No probs, I've been researching quite a few threads on this recently as I'm looking to do some similar work. In my case, I can release two bolts to remove a whole section, in your case you need to cut it out.

I understand that standard fit brake pipes are tough, explains why mine have lasted 13 years of road crap. So you are going to need something good to cut through the pipe.

As for stopping fluid loss, quite a few recommend clingfilm + cap on brake fluid tank to limit loss, as well as a custom "blocker" to each end (once split section is removed), while you work at it. (seen all sorts used from, old bleed nipple to golf tee!)

The pipes don't appear to be copper, look like stainless?  Should be interesting putting a flare on the cut end. I'm hoping that a pipe cutter will be man enough for the cutting job.

  The leak I have is right on the final bend where it meets the flexihose at the back, so it will be one bolt and a cut to get it off.  As for fluid loss I think a complete refill is in order.  My other half nursed the car back from Grimsby (50mls) with minimal brakes (really proud of her ) so there is not a lot left in the system

I had to do these on my estate for the MOT. Only vauxhall sell a complete pipe but any spares shop will sell you a length of copper.

The pipes are hard and I used a dremmel to cut the pipe. I then used two flaring tools to flare the end. The first shattered trying to tighten it enough to hold the pipe without it slipping!...the second better quality set did it first time, but I would defiantly recommend a complete system bleed!

You can drop the heatshields at the rear to get to them better!

There a mild steel pipe so a good clean cut, a spot of oil on the flaring tool die and gently form the flare......dont forget to fit the brake fitting on the pipe first.
