Today I changed the front and rear brake pads on my niece's 2003 Oldsmobile Alero 3.4. The car has front and rear disc brakes. Also I bled the brake fluid starting from rear passenger, rear driver, front passenger and lastly front driver. Somehow the brake pedal stayed soft. I repeated the bleeding but still the same. I have changed brake pads and bled the brake fluid plenty of times, but never had soft brake pedal at the end. My first thought was faulty master cylinder or brake booster, but when I went to Autozone the guy there told me I need special scan tool for ABS. So I didn't buy a new master cylinder since I didn't want to replace a good part. Now I'm confused.
Do you guys know what scan tool the Autozone guy was talking about? Is it a special GM scan tool? Or should I ignore what he said and go ahead and replace the master cylinder?
Thanks in advance
