Question: What is power brake service and why do I need to have it done?

Answer:

Imagine you pour a tablespoon of water into your hand and throw it as far as you can. Now suppose you suck up a tablespoon of water with a syringe, push the plunger and squirt it out. Which would go farther?

Obviously, the syringe would shoot the water much farther. That’s because you pressurized the water. Your power brake system is kind of the same thing. When you hit the brake pedal, the master cylinder pressurizes brake fluid, which activates the brakes so you can stop. If there is not enough pressure, you cannot stop.

A leak in your brake system would lessen, or possibly eliminate, your stopping power. Brake fluid attracts moisture which can cause detrimental corrosion. This would, in turn, create a leak. So a great way to keep your brake fluid free of contaminants is to change it as recommended.

The right amount of brake fluid is essential for the proper function of anti-lock brakes, traction control and stability control systems. Your NAPA AutoCare service advisor will survey your brake fluid level during a full-service oil change. If it is low that is a good indicator that a brake inspection is vital. Low brake fluid is most generally caused by worn brake pads.

Some of the signs of a leak are: reduced stopping power and spongy or hard pedal feet. If you suspect a problem, visit your local NAPA AutoCare Center today!
