Your car is complicated beast. Even if a component is working properly shows unusual signs, the problem should be addressed immediately as it is often a malfunction. A common example is when the brake pedal hits the floor but still works.
If the brake pedal goes all the way down when you press it, this problem can have several causes. But don’t worry, we explain how to fix your stuck brake pedal problems.
Brake Pedal Goes to Floor but No Leaks
If the brakes do not respond properly or the brake pedal “touches” the floor, this may indicate a leak in the brake system. This could be a brake fluid leak or a brake line leak.
When the car parked. The obvious sign of a brake fluid leak is a small puddle of fluid underneath. Brake fluid is similar to motor oil, but has a less “noble” consistency.
Master cylinder is another possible problem. The pan gaskets cylinder bore may be worn. Any times your vehicle’s brake pedal hits floor, you have to think about an internal leak bypassed pan seal.
A leaky pedal with no external leaks is one of the most common master cylinder symptoms caused by pan seals. This leads to a hydraulic pressure loss. It is likely that the vehicle is going too fast on the brake lights because the brake is weakening.
Brake Pedal Goes to Floor Common Reason
Here are some common reasons with details what is wrong when the brake pedal goes to the floor.
Leaking Brake Fluid
“Brake fluid” is an automotive term that you hear often and that you need to know. Without brake fluid, your car wouldn’t be able to stop at all.
Brake fluid is a compressible hydraulic fluid circulates through the brake lines. When you are pushed the brake pedal, pressurized brake fluid flows through the lines, creating a force that reason the brake callipers to behind on to the brake rotors and stop the wheels from spinning.
Brake fluid operates in a high temperature and high-pressure environment.
A Bad Brake Master Cylinder
Pressurized brake fluid is fed into the brake lines via the master cylinder, which acts as a pump in the vehicle’s brake system.
Cylinder piston seals can age and wear, which can lead to internal leaks. This is more likely if the brake fluid is contaminated.
For example, additional moisture can form in the brake fluid, leading corrosion of the master cylinder brake calipers and other brake line components. To contamination, the colour of the brake fluid should be checked at every regular oil change. Expert to replace your car’s brake fluid every four to five years.
While normal brake fluid is clear or light gold, contamination brake fluid is usually dark brown or black.

Defective Brake Booster
As you probably know, your car’s internal combustion engine works like a giant air pump and is powered by vacuum or compressed air created in the combustion chamber.
Many parts of your car use this vacuum to function and one of them is the brake booster. As the name suggests, a brake booster uses the engine’s vacuum to increase the force applied to the brake pedal time your press it down.
With this brake booster, you simply press lightly on the brake pedal to slow down or stop your huge vehicle. If the brake booster damage, significant force must be used to force the master cylinder to pump pressurized brake fluid into the system.
This means the brake pedal may be pushed beyond its normal travel fall to the floor. To better understand how a brake booster works with the other components of your braking system.
Brake Pedal Goes To Floor After A New Master Cylinder
The newly installed master cylinder may be damage and may not be able to produce sufficient pressure. In this case, the brake pedal may fall down when pressed.
The master cylinder may be damaged due to manufacturing detects or damage during transportation or handling. However, the master cylinder cover gaskets can be faulty, which can lead to internal leaks, especially if it is a used part.
Solution In this case, the master cylinder must be checked by a professional to determine if it is still usable. You will need to purchase a new master cylinder gaskets can cost between $150 and $230.
How to Use Brake
Operating and maintenance condition play an important role in the operation and service life of a vehicle. Bad driving habits can cause
Extremely rapid wear and tear.
The more frequently the brakes are applied, the hotter the components of the brake system become, including the brake fluid. As brake fluid heats up, it changes from a thicker fluid to a thinner fluid.
With thicker fluid the master cylinder requires less force to generate pressure to apple the brakes. Much more force is required for a thinner liquid.
If you have soft brakes but don’t notice any problems with your braking system, poor driving habits. Do not apply the brakes and remember to release the parking brake before starting the vehicle.
