R/O/S brake pipe

[KennyW]

Hi all,

I decided to check out the rear discs on the HDi and found the following

1. N/S appears okay stripped down clean and refitted
2 O/S uugh Disc is not in good condition, snapped bolt on removal but have spare and sorted,massive build up of oxidation on caliper and finally the brake pipe gave up the ghost. new one required

3. citroen service site refused to play ball part No 4885 E2 came up with error

Is there a temp repair which can be done, car required by SWMBO on Monday.

I make these up using the old one as a pattern, it's not hat hard if you have a pipe making tool, which I guess you don't.
Best bet if you are desperate is to hammer the broken pipe flat until you can get one .Assuming you are not driving too quickly, it will be ok, test for leaks with an assistant pressing the brake.
Obviously you do this at your own risk, but it will get you out of the sticky stuff

Don't even think about trying to fit a steel OE one Kenny - I've done it on an Anti-Sink car and it's hard enough with a nice flexible Kunifer one. You will need to recover the clamp off the old pipe before the curl (drill the rivets out) and then refit it to the new pipe using bolts. I think David (DHallworth) has got a pipe die, and he's just the other side of Glasgow, drop him a PM, to see if he can make one up.

Edit, checked service.citroen - that pipe is £63 near enough and it's the long one - I can't see how you would fit a rigid steel one without removing the anti sink gear, and probably the trailing arm as well! It gives the length as 2323mm - Martin at Pleadies will make one up if you give him a call, then you can make the spiral round a suitable mandril.

Thanks for the replies,

I've made a temp repair using leak off pipe & fuel pipe clamped to either end of the break

It's a shame that it can't be repaired by inserting a piece of pipe and threading the ends making a screw fix if you understand my thought process

Well, if you can put a flare on the end of a good section of pipe then Martin can supply a straight connector to enable a length of Kunifer to be spliced in... The problem is flaring the original pipe.

I did this on my Activa when I needed to repipe around the height-corrector...

i think you need to test your repair whilst you have the wheel off with suspension set to its highest and fully up,
now press hard on the brake pedle with engine running,

i would be very surprised if your repair didnt pop/ blow apart

If I'm reading this right too. It is BOUND to blow apart. I may be wrong, and someone will correct me if I am, there is approx. 2000+ psi available in the whole of the LHM system bar the return pipes.

The original pipes I have read somewhere are made of a wound steel to take the pressure as a standard copper pipe cannot withstand such pressures. But when I read about use of Cunifer (Cu - Copper, Ni - Nickel, - Fer - Iron) that presumably the standard brake pipe that is so often used on classic cars to prevent corrosion.

Whatever the truth, it pays to have a spare Citroen sitting on the drive at all times!

Thanks for the replies,

I think I can thread the original insitu and attached an adaptor and make a new pipe to caliper which would be better and cheaper.

Is Martin (Plaedies) adaptor designed for simple thread in or flaired piping?

Flared pipe end only Kenny I'm afraid. It's essentially a barrel with female unions at each end...

[KennyW]

Okay Jim,

I'll look for David Hallworths thread about the flairing tools etc.

Re the above pipe, Why is the pipe coiled near to the rear hydraulic strut offside
Otherwise why can't the pipe be straighter
I'll get a picture tomorrow.

That's a brake feed pipe to the rear caliper Kenny and the coils allow it to be flexible and move with the suspension. The coils wind up and wind down as the suspension arm moves up an down. Saves using a rubber flexi there.

You'll find the same coil arrangement where the main suspension feed leaves the pressure regulator and goes off to body-mounted components. The coils allow the engine to move around and not break the pipe in the process.

The reason the power assisted steering feed pipe has a big rubber flexi section and not coils is because the rubber section serves a dual role: that of being flexible and acting as a damper against vibration and pressure pulses you'd otherwise feel through the steering wheel.

Thanks for the reply Jim, interestingly I've found a company which sell PVC coated stainless steel replacements for both sides on the rear for £35.

Is it worth the look

Definitely worth a look Kenny. Have you got a link?

[citronut]

definatly worth a look at those pupes as here is the OE price and part No. for the O/S/R ,

Part Number Description Quantity Price excl. VAT Price incl. VAT Total incl. VAT Selection
96106389 HYDRAULIC TUBE 56.12 GBP 67.34 GBP 67.34 GBP ,

these are black powder coated steel pipes,
