But if there is no leaking fluid then that s not your issue.
Chevy truck brake pedal goes to the floor.
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.
My 04 hd had the pedal go to the floor but it was because the every hard line ruptured.
Abs works thats for sure.
But i m getting a pedal that when pumped will stop but otherwise is dropping to the floor board.
I then start the truck and the pedal goes to the floor.
With the engine off the pedal feels very solid.
Up until today the brake pedal was firm when pressed to stop.
When bleeding rear wheels the pedal will go to the floor when the bleeder is open.
Just disconnect the lines connect up bleeding fittings and hose and pump away.
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.
Well today is the first snow we ve had first ive driven it in the snow.
The final reason for a brake pedal to go to the floor is failing axle bearing.
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.
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.
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.
I have a 95 k1500 chevy stepside 350 truck with automatic trans.
Check the backside of each tire.
Axle bearings hold the brake rotor true without play while they both rotate.
The back brakes are low but in good condition not like the fronts at all.
I pump it several times with the engine running and it makes no difference in feeling.
Technically there are two main causes that would make the brake pedal sink all the way to the floor.
I would bleed the master cylinder which can be done in the truck.
The leak may coming from a brake line or one of the brake calipers on your vehicle.
I can still stop.
Reasons your brake pedal goes 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.
Finally there is a little switch under your dash that is held down turning the brake lights off when the brake is up.
