Most cars will feature a caliper in at least one set of the brakes. The braking systems in most automobiles these days generally feature front disc brakes and either back disc brakes or drums. The braking system, while designed to last for a long time, is not impervious to the elements or your driving habits. Over time, certain parts will need to be replaced or maintained in order to keep your brake system in good working order. Brakes, while complex, actually function in a rather simple manner. When you hit that brake pedal in the front of your car, the entire system goes to work.
The brake pedal allows the brake fluid to flow to the master cylinder in your braking system, directly to the brake caliper in your car. A special piston that is housed in the caliper will then receive pressure from the brake fluid, which forces the brake pads against the discs or rotors in your car. This applies friction and results in reverse inertia, which then helps the car come to a safe halt. Most cars feature only disc brakes in the front, but some feature discs on all four wheels. The calipers are prone to brake dust, the elements such as weather and moisture, and overall wear and tear. Over time, it will be necessary to maintain your brakes to ensure safe travels.
Gain advice from your mechanic:
Its advised that you avoid shops that only sell brakes, as they are tasked with doing the obvious, only selling brakes. Instead, ask your trusted mechanic what condition your brakes are in the next time that you have your oil changed out. Depending upon your driving habits, your brake pads should last you about 25,000 miles or even longer.
When to change brake calipers:
The calipers are going to need to be replaced every once in a while. They take on a lot of heat from the braking process, and also absorb dust, dirt, grime and moisture. This can cause them to become rusty or to leak, and to ultimately become less effective over time. Generally, if your calipers are worn out, the brake pads will need to be replaced as well.
How to Know its Time to Have Your Brakes Inspected
There are a number of different calling signs that are indicative that a brake inspection should be performed on your vehicle.
If your brakes squeal or squeak or whine when you are stopping, you should have them inspected. This could mean that the brake pads are worn down so low that metal is rubbing against metal.
If your car pulls hard in either direction when stopping it is the sign that one of your brakes is malfunctioning and should be inspected.
Spongy braking, as in the pedal needs to be depressed all the way to the floor, is a sure sign that something is wrong with your braking system.
Noticeable signs of brake fluid leakage are detectable. You should bring your car right into the auto shop if you notice this to avoid a brake system failure when driving.
