There are four primary reasons that brake calipers begin to stick: malfunctioning caliper slides, worn out brake hoses, dry or rusty caliper bolts, and debris inside the brake caliper piston. Because brake calipers have many different parts that need to perform different functions to provide their slowing and stopping power, there are many different possible reasons for a caliper to stick.
Brake calipers are an important part of a vehicle's braking system and can be dangerous if they are not functioning properly. If a car pulls to the side when it brakes, or if the brakes lose some of their stopping and slowing power, the vehicle may have sticking calipers. If a vehicle has malfunctioning caliper slides, the shims of the brake pads may be broken, jammed or corroded. This can cause brake calipers to stick. A broken brake hose, especially one that becomes partially blocked and acts like a valve for brake fluid, can also cause this problem.
Lack of lubrication and rusting in the different parts of the calipers can also cause caliper sticking. If the caliper bolts lose their protective rubber sheath and dry out, they can become rusty. This does not allow the caliper to slide the way it is supposed to. If a caliper piston becomes rusty, it will not move smoothly.Learn More
Some reasons why a brake pedal may depress all the way to the floor include loss of brake fluid, a faulty master cylinder or a bad brake booster. Drivers who "ride the brakes," or constantly depress the brake pedal while driving, can cause this condition.Full Answer >
Common causes of uneven brake pad wear include driving with warped rotors, a clogged brake line or leaky calipers. Vehicles that are heavier in the front than in the rear can wear brake pads unevenly due to an uneven distribution of weight. Debris in the breaking system, such as rocks or other foreign objects, wears brake pads down unevenly as well.Full Answer >
While disc brakes tend to last anywhere from 30,000 to 50,000 miles, the length of time brake rotors typically last depends on several different factors. These factors include how often the brakes are applied, how hard they are applied, the weight of the vehicle and how often the brakes have been serviced.Full Answer >
An air brake chamber is measured by locating size markings on the brake chamber or by measuring the diameter of the clamp holding the chamber together. Measuring the diameter requires a special tool, whereas locating the size markings may require the removal of dirt, corrosion or paint. Brake chamber sizes can be found in the vehicle owner's manual.Full Answer >
