What Causes Brake Calipers to Go Bad?
Brake calipers are a critical component of a vehicle’s braking system, responsible for slowing down or stopping the vehicle. Over time, brake calipers can fail, leading to reduced braking performance, uneven brake wear, and even accidents. In this article, we will explore the common causes of brake caliper failure, helping you identify the signs and symptoms and take preventive measures to extend the life of your brake calipers.
Wear and Tear
Like any other mechanical component, brake calipers are subject to wear and tear. The constant friction and heat generated during braking can cause the caliper’s moving parts to wear out, leading to premature failure. The following are some common wear and tear-related causes of brake caliper failure: (See Also: Are New Brake Pads Supposed To Squeak)
- Piston corrosion: Moisture can seep into the caliper, causing the piston to corrode and stick, leading to uneven brake pad wear and reduced braking performance.
- Seal failure: The seals around the piston and caliper can deteriorate over time, allowing brake fluid to leak out and causing the caliper to malfunction.
- Bearing wear: The bearings in the caliper can wear out, causing the caliper to vibrate and leading to uneven brake pad wear.
Brake Fluid Contamination
Brake fluid is essential for the proper functioning of the braking system. However, contaminated brake fluid can cause the brake calipers to fail prematurely. The following are some common causes of brake fluid contamination:
- Moisture ingress: Moisture can enter the brake system through the brake fluid reservoir cap or through worn-out seals, causing the brake fluid to become contaminated.
- Dirt and debris: Dirt and debris can enter the brake system through the brake fluid reservoir cap or through worn-out seals, causing the brake fluid to become contaminated.
- Brake fluid degradation: Brake fluid can degrade over time, becoming contaminated and causing the brake calipers to malfunction.
Improper Brake Pad Installation
Improper brake pad installation can cause the brake calipers to malfunction, leading to premature failure. The following are some common mistakes made during brake pad installation:
- Incorrect brake pad alignment: Misaligned brake pads can cause uneven wear, leading to premature caliper failure.
- Insufficient brake pad lubrication: Failure to apply the correct amount of lubricant to the brake pads can cause them to stick to the caliper, leading to uneven wear and premature failure.
- Over-tightening or under-tightening: Over-tightening or under-tightening the brake pad retaining clips can cause the brake pads to vibrate, leading to uneven wear and premature caliper failure.
Brake Rotor Issues
Brake rotor issues can cause the brake calipers to malfunction, leading to premature failure. The following are some common brake rotor issues:
- Warped brake rotors: Warped brake rotors can cause the brake calipers to vibrate, leading to uneven brake pad wear and premature failure.
- Scored brake rotors: Scored brake rotors can cause the brake pads to wear unevenly, leading to premature caliper failure.
- Brake rotor thickness variation: Variations in brake rotor thickness can cause the brake calipers to malfunction, leading to premature failure.
Caliper Misalignment
Caliper misalignment can cause the brake calipers to malfunction, leading to premature failure. The following are some common causes of caliper misalignment:
- Incorrect caliper installation: Misaligned calipers can cause uneven brake pad wear, leading to premature failure.
- Worn-out caliper slides: Worn-out caliper slides can cause the caliper to vibrate, leading to uneven brake pad wear and premature failure.
- Brake caliper mounting bracket issues: Issues with the brake caliper mounting bracket can cause the caliper to misalign, leading to premature failure.
High-Temperature Operation
High-temperature operation can cause the brake calipers to malfunction, leading to premature failure. The following are some common causes of high-temperature operation:
- Towing or hauling heavy loads: Towing or hauling heavy loads can cause the brakes to overheat, leading to premature caliper failure.
- Aggressive driving: Aggressive driving, such as frequent hard braking, can cause the brakes to overheat, leading to premature caliper failure.
- Driving in mountainous terrain: Driving in mountainous terrain can cause the brakes to overheat, leading to premature caliper failure.
Age and Mileage
Like any other mechanical component, brake calipers have a limited lifespan and can fail due to age and mileage. The following are some common age and mileage-related causes of brake caliper failure: (See Also: How Long Should My Brake Pads Last)
- High-mileage vehicles: Vehicles with high mileage are more prone to brake caliper failure due to wear and tear.
- Older vehicles: Older vehicles are more prone to brake caliper failure due to corrosion and wear and tear.
Conclusion
In conclusion, brake caliper failure can be caused by a variety of factors, including wear and tear, brake fluid contamination, improper brake pad installation, brake rotor issues, caliper misalignment, high-temperature operation, and age and mileage. By understanding these common causes of brake caliper failure, you can take preventive measures to extend the life of your brake calipers and ensure optimal braking performance.

Frequently Asked Questions: What Causes Brake Calipers To Go Bad
What is the most common cause of brake caliper failure?
The most common cause of brake caliper failure is corrosion. Brake calipers are exposed to the elements, and over time, moisture can seep into the caliper, causing corrosion to build up. This can lead to stuck or seized caliper pistons, which can cause the brakes to fail.
Can worn-out brake pads cause brake caliper failure?
Yes, worn-out brake pads can cause brake caliper failure. When brake pads wear down, they can cause excessive heat to build up in the caliper, leading to damage to the piston seals and other internal components. This can cause the caliper to fail prematurely. (See Also: How Much Is A Brake Job On F150)
Can dirty brake fluid cause brake caliper failure?
Yes, dirty brake fluid can cause brake caliper failure. Contaminated brake fluid can corrode the internal components of the caliper, leading to failure. It’s essential to regularly check and change the brake fluid to prevent this from happening.
Can overheating cause brake caliper failure?
Yes, overheating can cause brake caliper failure. When the brakes are subjected to excessive heat, it can cause the caliper pistons to seize or the brake fluid to boil, leading to failure. This can happen if the brakes are used excessively, such as when driving down long hills or in heavy traffic.
Can a faulty brake caliper cause other brake system components to fail?
Yes, a faulty brake caliper can cause other brake system components to fail. If the caliper is not functioning properly, it can put additional stress on other components, such as the brake master cylinder, brake lines, and brake rotors, leading to premature failure. It’s essential to address brake caliper issues promptly to prevent further damage to the brake system.
