Chevy Truck Brake Pedal Goes To The Floor

The first thing to check when your brake pedal goes to floor is to raise the hood and check the brake master cylinder s reservoir.

Chevy truck brake pedal goes to the floor.

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. Well today is the first snow we ve had first ive driven it in the snow. I pump it several times with the engine running and it makes no difference in feeling. I can still stop.

Abs works thats for sure. Technically there are two main causes that would make the brake pedal sink all the way to the floor. If the reservoir is empty or the brake fluid level is low there is most likely a leak somewhere in the brake system. The final reason for a brake pedal to go to the floor is failing axle bearing.

The fronts allow pedal travel to about 3 4 of the way to the floor and push fluid but then the pedal stops hard wont go to the floor and the fluid trickles out. The back brakes are low but in good condition not like the fronts at all. Finally there is a little switch under your dash that is held down turning the brake lights off when the brake is up. But i m getting a pedal that when pumped will stop but otherwise is dropping to the floor board.

Up until today the brake pedal was firm when pressed to stop. With the engine off the pedal feels very solid. 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. Check the backside of each tire.

I have a 95 k1500 chevy stepside 350 truck with automatic trans. I would bleed the master cylinder which can be done in the truck. 1 leak from brake line or brake caliper. Just disconnect the lines connect up bleeding fittings and hose and pump away.

Reasons your brake pedal goes to the floor. Also brake pedals tend to go to the floor when there is air in the line and they need to be bled but this only happens when the pedal is depressed. One of the reasons is the brake system loses pressure from an external brake fluid leak. The leak may coming from a brake line or one of the brake calipers on your vehicle.

But if there is no leaking fluid then that s not your issue. When bleeding rear wheels the pedal will go to the floor when the bleeder is open. Axle bearings hold the brake rotor true without play while they both rotate.
