I put new brake pads on the front of my 06 GMC Z71. After finishing, I noticed I didn't have any brakes. The peddle was spongy so I bled the brakes. And bled the brakes, and bled the brakes. I could never get the pedal to feel like it's supposed to. Took it to a mechanic and he bled the brakes. It still didn't fix the problem. After a major debacle of getting the wrong parts, the mechanic changed the master cylinder. The problem still wasn't fixed because the brake pedal wouldn't push down. So he then had to change the brake booster. When he took it off air "exploded" out of it. My question, is this normal? Why did changing my pads cause me to have $730.00 worth of repairs? I never once had any problems before. I had changed my pads because they had started "squealing." I bought the truck used with 80,000 miles on it, in very good condition. Any help would be greatly appreciated. Thanks!
