There are many signs and symptoms of a faulty brake caliper. If you come across any of the signs mentioned in this post, it is recommended and important to book your car in with a garage in Reading in order to keep it maintained for safe driving.


It is not unusual if excessive usage of your brake pads causes them to wear down faster than normal. However,When a brake caliper fails, what happens? Articles If your brake callipers are faulty, your brake pads will wear out much faster. 

Your vehicle will begin to pull to one side when this happens. This is why you should pay attention to whether or not your car is pulling to one side.

When your brake caliper is operating properly, the pistons within it will move in and out when you press and release the brake pedal (they react from the hydraulic pressure). Because of erosion or grime, one of the pistons within the brake caliper might lock up, preventing the brake pad from touching the brake disc. You'll notice that your car pulls to one side as you brake if this happens. As you remove your foot off the brake, locked calipers might delay the release of the brake pad. This, too, can cause the car to pull to one side. 

When you hear a screeching noise coming from your wheel region while driving, it might be a sign of a faulty or stuck brake caliper. This is not to be confused with the noise made when your brake pads wear out. When you apply pressure to your brakes, you'll hear that noise. If you hear any weird grinding noises, we recommend having your braking system examined by a competent expert at a car garage in Reading.

When a brake caliper fails, there's a good possibility your brake pads may wear down unevenly. If you look at your brake pads and see that one side has worn down faster than the other, it's possible that your calliper is to blame.

The hydraulic system provides pressure to your brake calipers, which allows them to work. As a result, if you see any hydraulic oil leaking (which is effectively brake fluid), it might mean your caliper is leaking. If you notice oil streaks on the ground near your tyres, you may have a leak.

Submerging an egg in a glass of water is said to indicate that it has gone rotten. The egg is still fresh if it falls over at the bottom of the glass. It is less fresh if it settles to the bottom and stands up, but it may still be eaten. If the egg floats on the water's surface, though, let it alone. It's gone sour. Of course, if you overlook the tell-tale signals of a rotten egg, your nose will pick it up as soon as you crack it open.

Your brake calipers are in the same boat. Your brakes will give you symptoms when they are worn out. If you ignore the indicators of a faulty brake caliper, they will become even less subtle, just like a rotten egg. The issue will become more apparent as the symptoms worsen. The end effect will very certainly be damage.

Having your braking system examined on a regular basis is the greatest approach to discover a faulty brake caliper. Corrosion, dirt accumulation, leaks, hesitant guide pins, and other early warning indications of a faulty caliper can be detected by a professional before they become a severe problem. If a caliper already has issues, the technician may discover uneven brake pad wear as a consequence of the caliper being jammed open or closed. With every oil change service, many repair garages provide a courtesy check in which a specialist inspects the condition of important vehicle systems and components, including your brakes. Otherwise, you should examine your braking system at least once a year.

You should get your brake pads replaced on a regular basis since they include a sacrificial friction substance that is designed to wear away over time. The length of time your brake pads will endure varies greatly. Inspections are crucial in this regard. Your brake pads will wear out faster if you brake abruptly or "ride the brakes." It's the same if you spend a lot of time on dirt roads. It's also important to consider the nature of the friction compound on your brake pads. Organic brake pads are less durable than ceramic or semi-metallic brake pads. In average, brake pads can last anywhere from 60 to 20 thousand miles before requiring brake repair.

If you detect any of the signs listed in this article, you should have your brakes examined as soon as possible. Delays in repairs might result in catastrophic damage to your brake system, putting you at risk on the road.

Go through and check MOT history of your car to establish if this was the reason for past failed MOT tests and if the necessary repair work was carried out.

The signs and symptoms of a faulty brake caliper

The braking system in your car is made up of several components that must operate together in order for the brakes to perform properly. If a component of the braking system is defective or worn out, it can have a catastrophic effect on the entire system, causing it to fail.

This is why you must have your car serviced and maintained on a regular basis to minimise any possibilities of accidents caused by brake failure.

A failed MOT test can also be caused by a faulty brake system, therefore it's critical to check MOT status of your car and get any faults fixed.

In this post, we'll go through the most common indicators of a faulty brake calliper so you can recognise them and take the appropriate steps to safeguard your vehicle's safety.

What is the function of a brake caliper?

It's critical to understand how your braking system works and how to spot faults in order to keep it maintained for safe driving.

Front-wheel or four-wheel disc brakes will be standard on the majority of vehicles. The brake pads within the braking system produce friction on the metal disc linked to the wheel whenever you press the brake pedal. This friction slows the wheel down, allowing your car to come to a halt.

The brake calliper is the hydraulic system that suspends the brake pads around the discs to aid complete this stop and start operation. As a result, when you press down on the brake pedal, hydraulic pressure is transmitted to the caliper via the brake lines. The brake pads are forced against the brake disc by pistons inside the caliper. When you take your foot off of the brake pedal, the caliper assists the brake pads in pulling away from the discs.
