I'm trying to troubleshoot a braking issue where the car brakes to right side. Its noticeable at high speeds when it pulls the wheel slight to the right on braking. It is not that noticeable at lower speeds. I also am troubleshooting why the distribution block piston pushes back towards rear, causing brake warning light to come on. This is what I have done so far (car is front disk / rear drums all original):
Prior to working on braking system:
* brake warning light constantly on
* car did not brake that well.
* rear drum brake were barely worn. Front brakes were worn about half way through.
Work done so far in order:
1) bled brakes and warning light went off until I rode it a few blocks before coming on. Repeated this twice and same result
2) changed all 4 brakes
3) noticed I had to pump twice while braking. I thought it was the way i bled them so did it another two times.
4) Replaced master cylinder, changed brake fluid and pedal sinking issue fixed.
5) I bought the proporting valve/distribution block rebuild kit from cougarparts and rebuilt them. Prior to rebuild, distribution block piston was stuck hard to one side. It was somewhat cruddy in both parts but not terrible. I cleaned them inside and out and replaced 0-rings and spring. Pistons now moved nicely.
6) I put everything back together and tested the light before bleeding. Light was off. While bleeding the rear passanger (1st step), the light came on and remained on throughout the bleeding.
