Why do my brakes go to the floor when i start my car.

Reasons your brake pedal goes to the floor. Pressure on the brake fluid cases the brakes to be applied to the wheels. The most common reason this happens is because you have a leak in one of your lines. Low brake fluid level.

No brake pressure pedal goes to floor. Here s an additional reason a brake pedal could go all the way to the floor. 1 leak from brake line or brake caliper. Also if a leak occurs in the system it will be unable to build pressure due to the lack of fluid causing the brake peddle to travel to the floor which can be followed by the brake system.

If you step on the brake pedal and it has little to no pressure and goes all the way to the floor especially if you re getting no braking. When you are ready to leave for work after your car has sat for a prolonged period of time check the ground underneath your car for puddles. The leak may coming from a brake line or one of the brake calipers. Check your brake fluid.

One of the reasons is the brake system loses pressure from an external brake fluid leak. A bad brake booster. If your master cylinder doesn t work properly or only works sometimes you re going to lose braking power and occasionally your brake pedal will go all the way to the floor. Another common reason why your brake pedal may go down to the floor is because you are running low on brake fluid.

If it s low top it off to the mark on the side of the reservoir.
