Brake pedal goes floor. Changed brake booster, no change. No visible leaks. Also, bled the brakes. Pulled vacuum hose off brake booster and covered with tape and I get resistance. All new pads on back and front. Confused
Brakes not working good so I changed both front and rear brakes. It looked
like the rear brakes were doing more. Even after doing this pedal going to
floor. Changed brake booster and bled brakes. Still going to the floor. No
noticeable leaks from master cylinder. I pulled vacuum hose from brake
booster and cover it with tape and I get resistance on the pedal.
