The caliper has a simple structure. It consists of a cylinder with a piston, a movable bracket that moves on guides, a fitting and anthers.
The most common causes of failure:
- A common cause of caliper breakage can be easily called as a anther damage. The piston is made of steel, durable and resistant to corrosion, but over time, due to interaction with the environment, it may become rusty.
- The piston has a floating fit relative to the installing place, so even slight corrosion can cause poor mobility. One of the common causes of damage to anthers is unqualified maintenance. For example, when pads are changed by inexperienced technicians.
Problems in working capacity of brake calipers
The brake fluid, despite the running time of the car, must be changed at least once every three years, before acritical watery surface. In the places where the climate unlike is very humid environment, it is better to change the liquid once a year.
Discs and pads wear. Severe wear leads to the caliper piston extends further to create the proper braking force. Because of this, the integrity damage of the anthers, leakage or jamming of the brake caliper may occur.
To avoid problems with the caliper, it is necessary to check the condition of the whole system: replace worn elements, broken parts, lubricate the guides on time.
What to do if you have problems with the caliper?
Have a look at the most common signs of the unit failure:
- Brake fluid leakage. To avoid this, it is necessary to check the level of brake fluid in the tank, inspect the outer and inner surfaces of the calipers. If there are traces of oil and stains, immediate help of professionals is required.
- Fluid leakage is in the gap next to the piston and cylinder or through the fitting. In this case, it is necessary complete dissembling of the unit with the subsequent replacement.
- A car, without apparent reason, is driven away while braking. When the suspension and tires are in perfect conditions, the similar behavior of a car may indicate a difference in braking forces. The cause of the breakage is the brake caliper jamming.
- The metal grinding of the pads indicates a breakdown of the caliper guides. The caliper is jammed due to the damage of the anthers.
- Overheating of brake discs. While moving and braking, the discs can be so hot and smell of burning, it is almost always a matter of the caliper jamming.
Specialized workshops use professional equipment manufactured by MSG Equipment for high-quality diagnostics and repair of brake calipers. Using the bench, you can easily check the caliper for leaks. MS300 bench checks the caliper performance before repair and after its completion. The stand helps a technician, without unnecessary efforts, to identify the unit leak, pressure drop under load. This equipment checks the correct operation of the brake system.
