Failures of the disc brake wheel caliper

• mechanical damage of the part;
• jamming of component in the caliper;
• component wear;
• caliper deformation;
• component displacement;
• pads corrosion;
• caliper anchorage displacement;
• piston boots wear.

Signs of failures of the disc Brake Calipers

• extraneous sounds at brake pedal pressing;
• vibration and beating vibration when braking;
• car skids;
• knocks at the suspension that disappear only when braking;
• worsening of vehicle response;
• difficulties in passing the turns;
• excessively free brake pedal travel.

Causes of failures of the disc brake wheel caliper

• air in the brake unit;
• dirt and dust impact;
• frequent temperature changes;
• installation of low-quality components;
• driving on rough roads;
• incorrect caliper fixation;
• sporting driving style.
• use of low-quality consumables;
• poor maintenance of the system.

Diagnostics

Experts recommend to diagnose the caliper condition every month. At first inspect the unit. Then estimate the general condition of all braking system. For example, you can test it, having accelerated the car up to 80 kilometers per hour (be sure the road is even and dry). After that  press brake pedal sharply. There should be no unusual sounds and change of the path. Also don't forget to ensure that there is a grease in the unit and all the components are working correctly. Diagnose the braking system after every 20000 operational kilometers.

Repair and replacement of disc Brake Calipers

Calipers wear out rather often (it is interesting that front calipers demand replacement 2–3 times more often than rear). It will be reasonable not to make replacement at once, and repair them after consultation with experts. The component will be disconnected and cleared of braking fluid and oil at the service station. After that the calibration of the caliper and replacement of gaskets will be carried out. If the part is beyond repair, it is necessary to perform replacement.
