Myself and a friend of mine just put new brakes on my 1991 Honda Prelude
Si. We did the rear brakes, replaced the calapers, rotors, pads and then
bled them all, front and back. We bled them all 3 times and refilled the
brake fluid in both the booster and the ALB system. After all this the
brakes are still very soft. I have to press the pedal almost all the way
down to get any stoping power.
