Hi, Ive been having some trouble sorting out the brakes of my 90 Bighorn.
My brakes seem to have lost a lot of stopping power, with hardly any power if I press more than once in a short space of time.
The check light also flicks on when braking hard, and will stay solid on the 2nd time braking (as above).
I have tried another booster, bled the lines,visually checked master cylinder,lines and calipers for leaks and checked for vacuum.
there is also no fluid loss in the master cylinder, but im assuming that I would have low pedal pressure problems if there was a leak? The pressure seems fine.
Anyone have any suggestions?
