Chevy Truck Brake Pedal Goes To The Floor

With the engine off the pedal feels very solid.

Chevy truck brake pedal goes to the floor. I have a 95 k1500 chevy stepside 350 truck with automatic trans. 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. Up until today the brake pedal was firm when pressed to stop. One of the reasons is the brake system loses pressure from an external brake fluid leak.

If the reservoir is empty or the brake fluid level is low there is most likely a leak somewhere in the brake system. Well today is the first snow we ve had first ive driven it in the snow. 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. Check the backside of each tire.

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. 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. The back brakes are low but in good condition not like the fronts at all. The leak may coming from a brake line or one of the brake calipers on your vehicle.

1 leak from brake line or brake caliper. Reasons your brake pedal goes to the floor. 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. Just disconnect the lines connect up bleeding fittings and hose and pump away.

I then start the truck and the pedal goes to the floor. I pump it several times with the engine running and it makes no difference in feeling. The final reason for a brake pedal to go to the floor is failing axle bearing. But if there is no leaking fluid then that s not your issue.

But i m getting a pedal that when pumped will stop but otherwise is dropping to the floor board. Finally there is a little switch under your dash that is held down turning the brake lights off when the brake is up. 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.

I would bleed the master cylinder which can be done in the truck. 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. Abs works thats for sure.
