Brake Pipe replacement...

I need to replace my brake lines early this year, the two long ones that run from front to back, is this expensive to get done as I don't have any flaring tools etc.

I reckon the two flexis' will probably need doing as the unions look pretty corroded. The two short axle pipes have been done previously before I bought her.

I see there are two connectors under the front passenger footwell near the chassis rail and the pipes from there forwards looks ok too.

it's a 1994 300tdi ES with ABS.

Thanks

shouldnt be more than £6o about an hours work

be cheaper to buy a flaring tool and do it yourself, easy to do.

I would change all the pipes at the same time, not connect new to old, false economy

did all mine this year £30 quid the lot, 2 hours work fitted braided flexibles at same time

Hmmm,

is there a specific type of pipe and fitting??

The bay seems to be full of copper brake pipe, which i guess wont rust at least? And various fittings both metric and imperial?

Is there a standard size ??

Dave

It seems the pipe is always 3/16" and nuts *should* be 10mm x 1mm thread.

copper pipe is fine apparently.

Does that sound about right?

If you are ok doing it yourself but don't want to get a flaring tool etc you can by the complete kit as HERE. I am sure other dealers have them cheaper.

Copper pipe is supposed to last a lot longer than "normal". I had mine all done in copper, and the flexis done at the back as well. The independant dealer charged about £100 inc VAT. It was mid winter (as now!) and I can't get the Disco in the garage so wasn't going to take the job on outside...

On a long summer day I would probably do it myself, many do. I have bled them before (and changed disks/pads) but this seemed a bit big for me as a winter job.

Just gonna make a comment then noticed your location so probably a bit colder where you are.

I need to change my Brake Calipers, but with 6 layers of clothing its usually warm enough to get the job done.

I may come and watch ya Brian..... if I can find 6 layers.....

Copper will never rot, nicosil will "eventually"

got mine from local auto jumble

pays your money takes your choice, copper being more expensive, sorry not much help there

3/16 is correct pipe use connectors to match the pipe

Those kits look good but are all non-abs models, also i only really need to do the two long pipes as the front and axle ends seem to have been done.

Query:-
I have TWO pipes running along the chassis and two flexi pipes to the rear axle. i always thought dual circuit brakes were split front / rear which would only give me one pipe, is this one split diagonally or is it the ABS or what??

Just wondering as if the two pipes are reconnected wrongly i will end up split left / right which could be a little entertaining if one circuit ever fails

My front drivers side caliper is leaking and as leaked out all the fluid from the front half of the reservoir. I drove it home with spongy brakes that were not pulling to either side, just gave the impression the rears only were working a bit.

I also presume the split is front/Rear

Aah then so it must be the ABS plumbing.

I'll be double careful to connect them back up the right way round then.

Yes,its the ABS,the ecu needs to have control of each wheel independantly - get the pipes the wrong way round and the ABS lamp will come on the first time the ABS becomes active on the back wheels.
I always use copper nickel tubing as it is more resistant to damage than plain copper.Not important you may think,but my Disco gets worked in the woods quite alot and back in the summer my 3 month old front to rear pipe got stretched badly by a big stick.It didnt break or leak but I think it would have had it been plain copper.

Great stuff, another bit of info learnt.

the most offroad mine goes is towing a trailer across a field so very little chance of damage, i'll route them as far out of the way as possible.

new just need the weather to cheer up a bit.

They look as though they should do the job

have a look locally as you may find brake pipe cheaper in a motor factors, typically, nowadays eBay is not the cheapest so just check it out with a phone call first

There are quite a few videos on YouTube showing how to do the flaring properly, worth a look.

I’m in a similar position to the original poster here. My rear brake pipe needs replacing too. I have been told by my local mechanic that it could involve having to remove the body. Wtf?? Should I go elsewhere or is he actually telling me the truth? Do some Discovery’s need their bodies removing to replace the rear brake pipes? I can’t believe this is right. If it is, anyone want to by on 03 plate disco?
