Power Brakes

The brake booster and braking system functions

The braking system is made up of a circuit of hydraulic pipes that connect each wheel’s brakes to a master cylinder. The brake pedal controls the system, while the brake booster increases the pressure in the pipes so you can stop safely and effectively.

The power brakes system helps you provide braking power so you don’t have to do all the work with your brake pedal. When you step on the brake pedal, you create pressure in the power booster, which is multiply by vacuum in the engine. The resulting pressure pushes brake fluids through the master cylinder into tubes and hoses that runs to the brakes in each wheel.

The importance of a brake booster and braking system

The braking system is vital to your vehicle. Without it, you can’t slow or stop your car. In order to keep your brake system run smoothly, you should replace your brake fluids periodically. Replacing brake fluids prevents corrosion damage to the braking system.

Brake fluid is responsible for moving the various components of the braking system. It is also known as hydraulic fluid, which means, moved or powered by fluids. Brake fluid protects the different metals used inside components, such as master cylinders, wheel cylinders, calipers, and ABS control valves. Also, the fluid protects against corrosion as moisture enters the brake system. Brake fluid is subjected to high temperature and, without it, your vehicle would not be able to stop. It must maintain a low level of compressibility under extreme temperatures, to accommodate in different environments.

You can trust one of our certified NAPA AUTOPRO technicians for the maintenance of your vehicle’s braking system.

How often do you need to verify your brake booster and braking system?

A soft or spongy brake pedal and irregular braking can be caused by leaking brake fluid or a master cylinder failure. When the brake fluid reservoir is empty, you will not be able to stop the vehicle with the brake pedal and will have to use the hand brake. A certified NAPA AUTOPRO technician will be able to find and fix the problem.

Make sure your brake fluid is filled to the recommended level. Also, it is important to make sure you use the recommend type of brake fluids. There are several kinds, and using the wrong one can lead to total break failure. There are two main types of brake fluid, glycol-based fluids and silicon-based fluids. Glycol-based fluids are classified by numbers (DOT) betwee3 and 5.1, which indicates the boiling point of the fluid.

As said before, brake fluid absorb moisture from the air, which will cause the fluid eventually to degrade. It is important to periodically drain the oil fluid of your brakes and replace it with new fluid. Every vehicle has different maintenance needs, check your owner’s manual for the recommended brake fluid changing period.
