2004 Gmc Sierra Brake Pedal Goes To Floor

If you still have a low pedal clamp off the 3 flex lines and see if the pedal gets better.

2004 gmc sierra brake pedal goes to floor.

2000 gmc sierra 5 3 vacuum booster i just had the same thing. I can still stop. Do not let the reservoir go empty. The abs kicked in then the pedal dropped to the floor.

System was not opened. 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. If no pressure builds up when pumping maybe wheel cylinder or caliper. Truck brakes were fine.

Axle bearings hold the brake rotor true without play while they both rotate. Technically there are two main causes that would make the brake pedal sink all the way to the floor. Rear system is in check and adjusted properly. The final reason for a brake pedal to go to the floor is failing axle bearing.

One of the reasons is the brake system loses pressure from an external brake fluid leak. If the pedal is hard to push then maybe booster. 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. Pumping does not bring it up.

I stopped just inches from the other car. It s important to not pump the pedal when doing the one part of the bleeding. Took 100 feet to stop at 35 mph. Does the pedal go to the floor with pressure on the pedal if so master cylinder.

Pedal offers some resistance but can be forced to the floor. Pedal takes substantial travel to stop the truck. System was only bled after the soggy pedal was found. Bleed the rest of the system starting at the right rear and move to the left rear then right front and finally left front.

A couple of ways to check. Added front pads and pushed pucks back then went soggy on the pedal. Reasons your brake pedal goes to the floor. 1 leak from brake line or brake caliper.

Was in a panic stop.
