Rear Brake Pipe corrosion and leak |
|
Sudden loss in braking going to work yesterday. Diagnosed as rear brake pipe leak and corrosion. Being told by local garage who are very good that the pipes do not look repairable and LR recommends body off etc....
Should I go down the route of doing a "proper job" on the 10 year old Disco and replace all the pipework as necessary with no additional joints what is the likely cost?
Any suggestion for a decent 4x4 specialist in the Plymouth region who could help would be appreciated as I suspect LR dealer cost would be prohibitive.

Each of the D3s I've had needed the rear brake pipe sections replaced.
Cut in above adjacent to the centre exhaust box as per dozens of posts on the forum.
I'd be amazed if the pipes aren't suitable to be joined in that location.
A properly flared joint should not be a problem whatsoever.
Last time I did it took under 2 hours for both sides (recommend getting new rear flexis and small rigid pipe while you're at it) including a bit of tidying up of other bits while I was there.
Job is slightly trickier with rear aircon equipped cars, just in terms of feeding through new pipe. Black 05 TDV6 HSE Auto

What he said...
Piece of cake really, pipes above the exhaust heat shield will be fine to cut and flare (it's lovely warm and dry up there)

Thanks.
Where would the small rigid pipe fit in?

You have the normal rigid pipe that runs front to back (the one that rusts!) and then there is a flexi where it goes from the body to the rear arms and then onto a small rigid pipe along the arm before another flexi to the caliper.

Thanks all.
Just spoke with mechanic who says that the brake pipes are corroded all the way to the turbo and above. He would I think understandably be unhappy to repair.
So - second opinion or call Roger Young in Saltash?

I'd get a second opinion, I've never heard of corrosion up that far to be honest even on much older, scruffier and more abused vehicles. The corrosion on brake pipes tends to occur in areas that are constantly moist open to the elements (and salt etc) and where there is something that chafes a little like the clips to expose the bare metal.
Anywhere there is heat tends to be pretty well protected.
I do stand to be corrected though.

Thanks.
That's the interesting thing - apart from road salt she has not been abused.
Just bad luck I suppose.

I'd get second opinion before citing bad luck.
Unless you mean where it has gone in which case it is a matter of time with all D3s in a UK climate.

Hi all trawling through posts trying to understand wtf happened to the ole gal today... low level brake fluid light came on . Aimed needed a top up. But 10 miles on way to home. Engine died and would not start. Only warning light is low level fluid. Yes it has blown a tear brake line... my as is . Is the a safety circuit that cuts the engine if it sees low low level in reservoir.
Thanks lads

Coming back to this. So...to do the full line from the rear to the block on the firewall, is it really a body off job for that? Doesn't really seem to be when I looked at it. More about feeding the replacement line up through.
LR may recommend a body off job, but is it really required? I have the full genuine LR pipe from the rear axle to the front of the vehicle.

I wouldn't use the LR genuine steel brake pipe, there are better options out there that will not corrode (Copper/Nickel). If you cut it and put a joint in then it can be changed without taking the body off relatively easily, you will find most LR specialists will have done loads of them as it is a common problem.

With all due respect, that wasn’t my question.

I think if you do want to fit an original part, and not have to bend it in the process, you do have to lift the body off the chassis.
That’s what LR say is necessary. I’m not sure if anyone has ever proved them wrong.

a question to anyone who has done this job replacing the rear sections:
did you remove any bits for easier access to the pipes? Im a bit concerned about getting the new pipe in place. which way to feed from; front or back?
did you start by removing the existing brake line and use that as a template to bend a new pipe? or just started feeding pipe from one end and bend it "in place" ?
im planning to cut somewere where the pipe is straight, above the exhaust heatshield, and run copper-nickle pipes all the way to the flexibles.
Best Regards
Oscar
