Brake pedal goes almost to floor,new rear and front brakes, brakes have been bled to extreme,1998 gmc sierra,scary braking,
Hi I'm litoshop if you bled the system and get no results then your brake pump needs to be replaced now before replacing make sure your pads are installed correctly because if there not this to can cause this problem good luck. if this information has been useful please let us know thank you.
Do the rear shoes fit the drums?
When drums are resurfaced the shoes should be re-ground to fit in the bigger drums or they may/can flex ....loosing pedal firmness.
How is the master cyl?
Clamp off all brake hoses and check pedal firmness to see if problem is at the wheels or not.
