2004 Gmc Sierra Brake Pedal Goes To Floor

System was not opened.

2004 gmc sierra brake pedal goes to floor.

If the pedal is hard to push then maybe booster. System was only bled after the soggy pedal was found. Technically there are two main causes that would make the brake pedal sink all the way to the floor. If you still have a low pedal clamp off the 3 flex lines and see if the pedal gets better.

Pedal has remained at the floor. With truck running pump the brake pedal several times and hold pressure on pedal after third pump. If this bearing goes bad it will allow the brake rotor it move back and fourth which pushes the caliper piston back into the caliper creating an air gap. Do not let the reservoir go empty.

Pumping does not bring it up. I looked all around the truck for leaks from brake fluid there is none and the brake resiviour sorry for the spelling is still full. If no pressure builds up when pumping maybe wheel cylinder or caliper. Rear system is in check and adjusted properly.

Added front pads and pushed pucks back then went soggy on the pedal. Axle bearings hold the brake rotor true without play while they both rotate. Reasons your brake pedal goes to the floor. Was in a panic stop.

I can still stop. Does the pedal go to the floor with pressure on the pedal if so master cylinder. Truck brakes were fine. It s important to not pump the pedal when doing the one part of the bleeding.

I stopped just inches from the other car. The abs kicked in then the pedal dropped to the floor. A couple of ways to check. I took the truck on a 30 minute drive the other day and on the way back home my brake light came on and the pedal goes almost to the floor.

2000 gmc sierra 5 3 vacuum booster i just had the same thing. The final reason for a brake pedal to go to the floor is failing axle bearing. Took 100 feet to stop at 35 mph. Bleed the rest of the system starting at the right rear and move to the left rear then right front and finally left front.

Pedal offers some resistance but can be forced to the floor.
