Hi all ! I have a 1993 Bonneville with 135k miles on it. The brakes were working fine however the master cylinder was leaking at the rear seal. I went ahead and put in a new master cylinder however now I can not get the brakes to work. I've bled the brakes several times (I've bled other brakes in the past and assuming there is no special method of bleeding these brakes, I'm sure I did it properly). Based on old info posted in this group, I thought I may have a faulty new master cylinder so I went ahead and got another new one --- same problem.
The problem with the brakes is no pressure. The pedal goes all the way to the floor.....If I pump the brakes - I'll get brakes but they are very spongy.
The hose that comes off the master cylinder reservoir and goes down near the radiator - I assume that is the ABS system. Is there anything I need to do to that unit to bleed the brakes ?
Any other ideas ?
THANKS
