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.
