Understanding Brake Calipers

Brake calipers are essential components of a vehicle’s braking system. When you press the brake pedal, hydraulic brake fluid travels through the brake lines to the calipers. This pressurization causes one or more pistons within the caliper to extend, pushing the brake pads against the rotors. The friction generated between the pads and rotors slows down or stops the vehicle.

Key Functions of Brake Calipers:

– Friction Generation: Calipers apply pressure to brake pads, which creates the friction necessary to stop the vehicle.
– Heat Dissipation: As brakes engage, they generate heat. Calipers help dissipate this heat to prevent brake fade, ensuring consistent stopping power.
– Hydraulic Function: They convert hydraulic pressure from the brake fluid into mechanical force to clamp the brake pads onto the rotors.

Types of Brake Calipers

– Sliding Calipers: These have a single piston that moves back and forth, applying pressure to the brake pads. They are simpler and more commonly used in many vehicles.
– Fixed Calipers: These have multiple pistons (usually two or more) that apply pressure evenly to both sides of the brake pads. They provide better performance, especially in high-performance vehicles.

Frequently Asked Questions

Find answers to commonly asked questions about our products and services.

What does a brake caliper do?

Brake calipers play a critical role in the brake system. They are responsible for applying pressure to the brake pads, pressing them against the rotor to slow down or stop the vehicle.

What does a brake caliper replacement involve?

A mechanic will inspect the brake caliper, establish whether it needs to be replaced, and remove the faulty caliper. They will then fit a new or reconditioned brake caliper and bleed the brakes to remove any air. The vehicle is then tested to ensure the brakes are functioning correctly.

Can you replace brake calipers yourself?

It is not recommended to replace brake calipers yourself unless you are a qualified mechanic. Brake systems are safety-critical components, and an incorrectly installed caliper can result in brake failure, which is dangerous.

What are the symptoms of a bad brake caliper?

Common symptoms include uneven brake pad wear, a vehicle pulling to one side during braking, brake fluid leaks, or a spongy brake pedal. If you notice any of these symptoms, it may indicate a bad brake caliper.

How long does it take to replace a caliper?

A brake caliper replacement typically takes 1 to 2 hours, depending on the make and model of the vehicle and whether there are any additional complications during the repair process.

How often should you replace brake calipers?

Brake calipers are designed to last the lifetime of the vehicle, but they can fail due to wear, corrosion, or damage. There is no set interval for replacing calipers, and they should be inspected regularly and replaced if they are faulty.

Can a caliper be repaired?

In some cases, calipers can be repaired if the issue is minor, such as a sticking piston. However, if the caliper is damaged or corroded, it may need to be replaced rather than repaired.

What happens when a caliper goes bad?

When a caliper fails, it can cause uneven braking, pulling to one side, or reduced braking performance. If left unaddressed, it can lead to brake failure and create a safety hazard while driving.

How can I extend the lifetime of my brake calipers?

To extend the life of your brake calipers, regular maintenance is key. Keep the brake fluid clean and flush it as recommended by the vehicle manufacturer. Avoid driving through deep water or harsh environments that can cause corrosion.

Can you drive with a bad brake caliper?

Driving with a bad brake caliper is not recommended. It can impair braking performance and create an unsafe driving condition. You should have a faulty caliper replaced as soon as possible to maintain safe vehicle operation.

Can I replace just one brake caliper?

Yes, it is possible to replace just one caliper if only one is faulty. However, it is often recommended to replace both calipers on the same axle to maintain even braking performance.

Is a faulty brake caliper an MOT failure?

Yes, a faulty brake caliper can lead to an MOT failure. A caliper that is not functioning correctly can compromise the braking system and pose a safety risk, making the vehicle unfit to pass an MOT test.

What causes a brake caliper to break?

Brake calipers can break due to corrosion, wear, or damage from external factors. Contaminated brake fluid can also cause internal components to degrade, leading to caliper failure.

What is the average life of brake calipers?

Brake calipers can last anywhere from 75,000 to 100,000 miles, but this can vary depending on driving conditions, the type of brake caliper, and regular maintenance.

Are brake calipers checked during an MOT test?

Yes, brake calipers are inspected during an MOT test to ensure they are functioning correctly and there are no leaks or other issues that could impair the braking system.
