Simple Answers from Ernie’s Auto Service: Power Brakes

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

Ernie’s Auto Service Answer:

Let’s take, for instance, a plain ordinary garden hose.  When you turn on the water and it comes out the end it just pours and splashes out.  However, if there is a nozzle attached to the end of the hose, and you turn the faucet on and squeeze the nozzle, the water shoots outs.  Which water would go further?

Of course it’s the water squirting out of the nozzle. That’s because you pressurized the water. Your power brake system utilizes the same idea.  When you step on the brake pedal, the master cylinder pressurizes brake fluid which actuates the brakes so you can stop.  Vehicles which don’t have enough pressure – can’t stop properly. In some cases, when all pressure is lost, the brake pedal will go all the way to the floor board and the driver will not be able to stop the car at all!

A leak in your brake system would lessen – or even eliminate – your stopping power. Brake fluid attracts moisture which can cause harmful leak-inducing corrosion.  So a great way for motorists to keep their brake fluid free of contaminants is to change it as recommended by the car’s manufacturer.  You can find this schedule in your owner’s manual.

Enough brake fluid is essential for the proper function of any vehicle’s anti-lock brakes, traction control and stability control systems. Your professionals at Ernie’s Auto Service will inspect your brake fluid level during a full-service oil change.  If it’s low it may indicate that a thorough brake inspection is needed.

Low brake fluid is most frequently caused by worn brake pads. Some of the signs of a leak are reduced stopping power and spongy or hard pedal feel.  If you suspect a problem, come into Ernie’s Auto Service for a brake inspection right away.  Give us a call!
