Brake Fluid Leak

A common reason that makes a brake pedal go to the floor is the brake fluid found in your car! Basically, your car may be going low on fluid or there is a leak in any part.

Brake fluid may leak because of different damages to overall brake components as well as rusting. So, if you notice that your pedal is going down, the fault is on the brake fluid.

Air on Brake Lines

Another reason that your brake pedal may go to the floor is because of the air that is gathered in the brake lines of your car.

The brake lines are the parts of your car that transfer the pressure you give to the pedal onto the brakes in the wheels.

If these lines are filled with air, the pressure won’t be there anymore and you will be having problems with the pedal.

Failing Master Cylinder

The master cylinder is one of the most important components in a car when it comes to the brakes! A master cylinder’s job is to pump the brake fluid into the brake lines and once it is failing, there is no doubt that the whole brake system will not be as it should be.

Bad Brake Booster

Hence its name, a brake booster is a device that boosts the whole performance of the brakes and it increases the force that you apply on the pedal and takes it to the master cylinder.

When there is a bad brake booster in a car, there is no force and the pedal is very light and goes directly to the floor.
