The first suspect when a brake pedal goes all the way to the floor is an empty - or almost empty - master cylinder. It could also be a bad brake booster, a ruptured line, etc. The car should be TOWED to a repair facility, and the cause found and corrected before the car is driven again.
Something is impairing the brake pedal to go to the floor. Only a mechanic can tell you what is happening.
Defective master cylinder. Replace it ASAP
sounds like overheating of brake line, either from hot pavement, or cat converter. causes brake fluid to boil and loss of pedal.
It wasnt assembled right
A brake fluid leak in the system would do that. Check the brake fluid reservoir. If it is empty you are in need of brake work asap!
Probable causes: Low or no fluid in reservoir; Worn brake pads/shoes; Air in brake lines; Leaking brake line.
manualy lift brake pedal to see if they go out. if so check spring at pedal
A brake pedal going directly to the floor is a sign of a few things. First, you are in need of brake fluid. Second, the brake pads are probably almost worn out. They may be worn out past the point the ABS light would be active. The ABS light may also be burned out.
usually they will leak out the back by the booster, your brake pedal will slowly go to the floor at stops or the brake pedal will go right to the floor when pushed.
no you have a brake fluid leak somewere
It could be one of serveral things. - Low brake fluid. - Parking brake is on or slightly on. - If the brake pedal has been pushed all the way to the floor. Check the fluid and parking brake first then go to plan B.
ouch,are brakes adjusted correctly/ sit in vehical and pump pedal to get a full pedal,then hold pedal to see if it bleeds off and goes to floor,if it stays, replace shoes and pads if it goes to floor, there is a fluid leak somewhere is there brake fluid in the resevoir/ are there any brake fluid leaks ,check backside of wheels there is a brake fluid pump, on the chassis rail about level with the front of the front door on the left side.if this pump is bad your pedal will go to the floor
