1992 Buick Lesabre 6 cyl Two Wheel Drive Automatic 140000 miles
I have a 92 lesabre, and while driving the breaks became soft and the pedal went to the floor and it became hard to break. I checked all the breaks and lines but did not find any thing wrong. So I put in a new master cylander, and bled everything from back to front many times with no success. I then replaced the power brake air valve and the pedal still goes to the ground. Before putting in the new master cyl I checked the booster and all seemed fine. The only thing that I noticed was everytime I push on the pedal it makes one click sound and also on the way back up. Looking under the dash its a box with a buton that the break releases when you push them down. Dont know if it has anything to do with it but thought I would mention it
have the same problem?
