Why Does The Brake Pedal Go 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.

Why does the brake pedal go to the floor. You should be able to see brake fluid underneath the car if there s a leak in the system. Another possible cause is a bad brake master cylinder. If you have air in the line you will need to bleed your braking system.

If the reservoir is full try pumping the brake pedal to see if the pressure returns. 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. Check your brake fluid.

If it s low top it off to the mark on the side of the reservoir. Technically there are two main causes that would make the brake pedal sink all the way to the floor. Many drivers have reported that brake pedal goes to the floor after new master cylinder replacement.

The most common reason this happens is because you have a leak in one of your lines. This happens mainly if no air bleeding was done after installing a new master cylinder and thus there is air in the brake lines. This is pretty easy to diagnose.

Axle bearings hold the brake rotor true without play while they both rotate. This typically happens after after turning a hard corner. If your brake pedal sinks towards the floor when you are stopped while your foot is on the brake or does not feel as firm when the brakes are applied this could indicate you are having some sort of trouble with your brakes.

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. 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. The final reason for a brake pedal to go to the floor is failing axle bearing.
