ive just fitted a hydro to my bmw e36. its a 1998 so has the twin pipes going from the junction block to the rear wheels. i basically joined the two pipes together which come out of the junction block with a t piece then had one line coming out of that to the inlet on the hydro. then ive got one line coming out of the outlet on the hydro to another t piece then two lines coming out of the t piece (one to each rear wheel). ive basically done it the same as shown on some drawings which were posted on dw. ive bled the whole system coutless times, there is no air left in the system at all. the footbrake and hydro feel as they should and the footbrake pulls up really well however the handbrake does not lock the rear wheels. i can feel it slowing the car down but is nowhere near locking the wheels. will not even skid the wheels on gravel. ive fitted new discs and pads all round and have drove hundreds of miles to bed them in. Any idea why its not working as good as it should. Its a obp vertical lever hydro. Thanks, steven.
I cannot understand it, mine does not work much better than the cable handbrake which i also have on the car?
I had the same issue buddy, try.... pulling the handbrake back to full. lock it there somehow, then bleed your rears up as normal. worked for me if it doesnt work, i dont know, im only giving advice as to what worked for me
I bet thats the problem, if its not 0.625 it prob wont lock. Mine locks perfectly well even at 100mph. Either that or you got the input/output the wrong way round on the cylinder.
I'm having trouble finding out how I need to plum in the hyro on an E46.. Sounds like it may be a similar set up on the 36 - do you have this diagram of how it should work to hand?
The above diagram is exactly how ive fitted it and have double checked it. Is there any way of double checking what cylinder size i have by looking at it? I did not buy it directly from obp but from a shop that sells their products.
we had this issue with the obp hydros on e36s. in the end we put a longer handle on it. and only use the dw design ones now.
Ive just bought a brand new 0.625 cylinder so will fit that on this weekend and let you know if it works.
yep cylinder is your problem. i had the obp handle couldnt get it to work. switched to the silver project one which is double the height and 0.625 and it locks up perfectly.
Fitted the new 0.625 cylinder. It slows down the car a lot faster and has more bite than the 0.70 but still does not lock the wheels?
