Changed Brake And Still Now Pedal Goes To Floor

Axle bearings hold the brake rotor true without play while they both rotate.

Changed brake and still now pedal goes to floor.

Bled all lines front rear repeatedly but the pedal still goes to the floor. There is no leak anywhere. The final reason for a brake pedal to go to the floor is failing axle bearing. Changed all steel line at rear plus calipers and brake hoses.

Reasons your brake pedal goes to the floor. One of the reasons is the brake system loses pressure from an external brake fluid leak. I scanned the car and it says abs inlet valve coil left circuit and gave me c1201 code and i was wondering if someone can help me with it. To see if there s air in the lines or a leak then shut the car off pump the brakes and see if the pedal is still spongey soft.

Had a leak on steel line over rear axle. Only when the car is running i have the problem. 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 have replaced rear brake pads and rotors on my 2010 highlander and right after i went to take the car for the test drive the brake pedal goes all the way to the floor.

Technically there are two main causes that would make the brake pedal sink all the way to the floor. Because if you weren t filling the master cylinder as you were bleeding the brakes then their is a chance that you have a tone of air in the master cylinder and that would make the pedal go to the. If you still don t have a proper brake pedal you probably have a defective master cylinder while it doesn t happen often it isn t unusual to get a defective part right out of the box whether new or. Typically if you sit there at a stop and press the brake real hard then it will feel as if it s going to the floor.

If you have clean brake fluid at the wheels after following the proper bleed sequence i would try bench bleeding the master cylinder one more time and bleeding at the wheels afterwards. If the reservoir is empty or the brake fluid level is low there is most likely a leak somewhere in the brake system. If this bearing goes bad it will allow the brake rotor to move back and fourth which pushes the caliper piston back into the caliper creating an air gap. The leak may coming from a brake line or one of the brake calipers on your vehicle.
