I have a 99 blazer 4wd with 148,000, miles. It has a 4.3liter in it. I just redone all the brake pads and rotors. While bleeding the rear brakes (having someone pump the brake pedal and holding pressure) it seemed to release approx. Half the fluid as the front brakes. (Seemed normal to me). Approx. 2 weeks later the pedal became intermittent. Sometimes soft. Sometimes firm. Did not always feel like the rear brakes were grabbing. Seems to happen mostly when braking slowly. Tried to bleed rear brakes again. Same thing happened again. Can you possibly lead me to a conclusion. Iam going to look for a leak at the check valve on the power assist in the morning. Any other suggestions? Sorry, one thing I forgot to add was that I have 4 wheel disk brakes. And I am not loosiing brake fluid. The resevoir holds a consistant fluid level.
