Just finished replacing master cylinder. Old master cylinder had a lot of black trash in the resevoir. The problem is a lot of travel play until the pedal gets firm and the brakes start applying. I bled the system and got dark fluid from
all bleeder valves. I bleed the system until the fluid was clear.The instruction and troubleshooting chart that came with the master cylinder says the master cylinder compensating ports blocked..Is this the same as the proportion valve? There is a block measuring 4 9/16" long and 2 1/2" high with a 19mm bolt hear on each end.The rear one has a black cap on it.there is some fluid leaking out of the black cap. The front part of the resevoir line is connected to the front of the block and the rear line going to the rear. If this valve has trash blocking something, could this cause my problem? How would I get this trash out of this. I can hear the rear brakes applying but not the front. On rare occasions I got ABS light on the dash,but only for a few seconds.Next time I restarted no light except the first 3 seconds. Any help will be appreciated.
