Chevy Truck Brake Pedal Goes To The Floor

Up until today the brake pedal was firm when pressed to stop.

Chevy truck brake pedal goes to the floor.

I pump it several times with the engine running and it makes no difference in feeling. I have a 95 k1500 chevy stepside 350 truck with automatic trans. 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. Technically there are two main causes that would make the brake pedal sink all the way 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. My 04 hd had the pedal go to the floor but it was because the every hard line ruptured. One of the reasons is the brake system loses pressure from an external brake fluid leak. I can still stop.

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. 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. With the engine off the pedal feels very solid.

The final reason for a brake pedal to go to the floor is failing axle bearing. If the reservoir is empty or the brake fluid level is low there is most likely a leak somewhere in the brake system. Just disconnect the lines connect up bleeding fittings and hose and pump away. 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. 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. Reasons your brake pedal goes to the floor. 1 leak from brake line or brake caliper.

I then start the truck and the pedal goes to the floor. Abs works thats for sure. When bleeding rear wheels the pedal will go to the floor when the bleeder is open. Check the backside of each tire.

The leak may coming from a brake line or one of the brake calipers on your vehicle. Finally there is a little switch under your dash that is held down turning the brake lights off when the brake is up. Well today is the first snow we ve had first ive driven it in the snow.
