Brake Pipe's (rear hose to front) excessively corroded

[Blaze One]

Hello chaps,

I see this topic was started some time ago - however last reply was approx two years ago so would be most grateful for some assistance ...

I own a P-Reg (1996) BMW 318is Coupe which has recently failed its MOT:

Nearside rear (rear hose to front) Brake Pipe excessively corroded
Offside rear (rear hose to front) Brake Pipe excessively corroded

Can anyone tell me how much this should cost to replace (the man at the garage was honest to tell me not to get it done at his boss' garage as I would've been ripped off!) and if anyone knows of a good independent around the west london (hounslow, ealing areas) region.

Cheers gents

The fuel tank has to be dropped to replace those and parts and labour would be about £250.00 as the new pipes from BMW come as a kit and need bending to suit. You will also most likely need a couple of inner flexi hoses at the rear. Exhaust needs removal as do the heat shields. With all that expect £350.00. PhoenixMotorsport are not too far from you and have done this job a few times.

It's quite common on the E36's and mine on my old M3 evo were not nice when they failed the MOT, very glade they were spotted.

With regards to price, I seam to remember the parts were fairly cheap, I can't remember the exact amount but under £50 rings a bell.

Fitting is a horrible job as said above the fuel tank needs dropping down, The job took me and a friend a couple of hours and I wouldn't recommend trying to do them without a ramp, I'd expect to pay at least £150-200 all in.

I too have to undertake the replacement on the rear pipes for an MOT. I was under the impression that you could drop the tank without removing the prop, effectively allowing the tank to balance on it and sag at either side.

This allows you to feed the pipes from the brakes through the access hatches under the rear seats through to the T-Piece connectors where you can rejoin them.

Has anyone attempted this, and can anyone recommend the correct flaring tools and additional equipment/piping that might be needed.

My e36 318 needed the brake lines doing to.
While it was being done, i had the goodridge lines fitted, well worth it.

I never dropped the prop down, letting the tank down just about gave us the room to work.

It was a couple of years ago now but if i remember correctly we just used a standard brake spanner and mull grips, It was quite scary how easily the pipes snapped and I was very pleased that the MOT guys picked up on the lines.
