I have converted my 92 SC over to conventional power brakes and I am having the same problem I had when the ABS was in. I had a hard pedal that would barely stop the car. After posting here, I was told that it was either the accumulator ball or the ABS unit. After checking prices (Acc. Ball $120, ABS assy $700) it wasn't a hard decision. I installed the new ball and still had a hard pedal even after letting it pump up. I sure wasn't going to drop the money on the ABS assy, so I did the swap. Just finished it up Friday night and took it for a Drive on Saturday. I still have a hard pedal. If I press gently on the pedal, it will apply the brakes with an almost feel. Can you give me some Ideas of where to look to fix this? Info about the swap- Booster from 90LX bird, MC from a 97 CV (Ex.Service vehicle) and I swapped out the Booster Push rod with a 1/4x3/4x1 bolt that I ground down and fit perfectly. Bled all four wheels starting from the rear pass., Rear driver, then Pass front and Driver front. Got all nice clean fluid and looks like all air is out. May try again Sunday just to make sure, but any Ideas you have will be appreciated.
