Brake Caliper repair & service made easy

How does a brake caliper work?

The brake caliper is a vital part of your car’s disc braking system. When you press the brake pedal, hydraulic fluid from the master cylinder flows to the brake caliper. This pressure forces the caliper’s pistons to press the brake pads against the brake disc (also called a rotor), which spins with the wheel.

The resulting friction between the brake pads and the disc slows down the wheel’s rotation, helping to bring your car to a safe stop. Without properly functioning brake calipers, your braking system wouldn’t work effectively—making the vehicle unsafe to drive.

The caliper ensures smooth, controlled braking by applying consistent pressure to the brake pads whenever you need to slow down or stop.

What does a brake caliper replacement job involve?

During a brake caliper replacement, the mechanic will follow a clear and systematic process to ensure your braking system works properly again. Here's how it typically goes:

• First, the mechanic inspects the entire braking system, checking for any issues with the brake calipers. The calipers are responsible for pressing the brake pads against the wheels, so if there’s a problem, it can affect your ability to stop the car safely.
• Next, if the mechanic identifies a faulty brake caliper, they will remove the damaged one and replace it with a new, high-quality caliper.
• The mechanic will also assess the condition of other braking components, like the brake pads or rotors, and advise if any parts need replacing to make sure your braking system is in top shape.
• Afterward, the mechanic will bleed the brake system to remove any air trapped in the brake lines, which could prevent your brakes from responding properly. This step ensures the braking system functions efficiently and safely.
• The mechanic will also top up the brake fluid to the proper level. Adequate brake fluid is crucial for your brakes to work effectively.
• Once everything is in place, the mechanic will take your car for a short test drive to check that the new caliper is functioning correctly and that the entire braking system is working smoothly.
• Finally, the mechanic will recheck the system and make any necessary adjustments to ensure your brakes are performing at their best.

How do I know whether I need a brake caliper repair or replacement?

• If you notice a reduced braking performance, where the car doesn’t stop as quickly or efficiently as it should, it could be a sign that the brake caliper isn’t working properly.

• If the vehicle pulls to one side when you apply the brakes, it suggests that one of the calipers might not be applying pressure evenly, which can cause an imbalance in braking.

• You may hear high-pitched or squealing noises when braking. These sounds can often come from worn-out or damaged calipers, which may cause the brake pads to wear unevenly.

• If the car seems to hold back or doesn’t roll freely when not pressing the brake pedal, it could indicate that the brake caliper is stuck or not releasing properly.

• Leaking brake fluid around the wheel rims is another sign that something may be wrong with the brake caliper. Leaks can lead to a drop in braking power and pose a safety risk.

• A burning smell after heavy braking could point to overheated brake pads or a malfunctioning caliper that’s causing excess friction.

• If you feel vibrations when braking, this could indicate that the caliper isn’t applying even pressure, causing the vehicle to shake or judder when you try to stop.

• Uneven brake pad wear is a key indicator of a failing brake caliper. When a caliper isn’t working correctly, it can cause the pads to wear down at different rates, making stopping less effective.

• Lastly, if you see a brake warning light on your dashboard, it’s a good idea to have your calipers checked. This light can indicate a problem with the braking system, which could include issues with the calipers.

If you notice any of these signs, it’s important to have your brake calipers inspected by a professional mechanic as soon as possible to ensure your vehicle’s safety.

How often should a brake caliper be replaced?

Brake calipers generally don’t have a set replacement schedule, as their lifespan can vary, however, they typically last anywhere from 75,000 to 100,000 miles. That being said, they may need to be replaced sooner if you experience issues such as reduced braking performance, unusual noises, or signs of damage or wear.

Can a brake caliper be repaired?

In many cases, your brake caliper can be repaired rather than replaced. While it's possible to take the caliper apart and refurbish it, it's usually more cost-effective to replace the part, especially if a new one is readily available. This can save you time and money while ensuring your brakes perform at their best.

How much does a brake caliper replacement cost?

The average cost of replacing a brake caliper is around £180, with prices typically ranging from £150 to £220. In some cases, additional parts like the brake pads may need to be replaced depending on the extent of the issue, which can add to the overall cost. The final price for the brake caliper replacement will depend on your vehicle model and the specific parts recommended by the manufacturer.

What does a ClickMechanic brake caliper replacement quote cover?

Unless otherwise stated, the quote for your brake caliper to be replaced will cover;
* The cost of the brake caliper
* Coming to you or collection and return delivery (if still drivable)
* Fitting of the parts
* Disposal of the old parts (unless you request to keep them)
* VAT (if applicable)
* 12 months parts and labour warranty

Can the brake caliper be replaced by a mobile mechanic?

Yes, in most cases, a mobile mechanic can replace the brake caliper, as long as the job is safe to perform at your location. A mobile mechanic can typically handle the task if the car is not excessively large, the brake system is not too complicated, and there’s a safe and suitable area to work in.

However, if additional complications arise, such as needing to replace other parts of the braking system or if your car requires special tools or equipment, it may be necessary to take the vehicle to a workshop. A professional mobile mechanic will assess the situation before proceeding to ensure the job can be done safely and efficiently at your location.

If the vehicle is drivable, there is no collection and delivery fee for bringing the vehicle to the garage if needed.
