What does a brake caliper do?

Brake calipers are an essential part of your car's braking system. The job of the caliper is to slow the car's wheels by creating friction with the rotors. The most common is floating caliper, but on some cars there are swinging and fixed calipers. It fits over the rotor like a clamp. Inside each caliper is a pair of metal plates bonded with the brake pads.

When the driver presses the brake pedal, the small brake cylinder piston compresses brake fluid in the master cylinder. Because the brake fluid doesn't compress, this force is instantly transmitted to the brake caliper, which clamps the spinning rotor, causing the wheel to slow and stop.

Though only comprising a few parts of your car, brake calipers are one of the most critical parts, enabling controlled braking in various situations. As they are a key safety component of your car, it’s important that your brake calipers are well maintained and fully functioning at all times. If you think there may be an issue with your calipers or braking system, it’s important to get things looked at by a mechanic as soon as possible.

Ford

The Ford Motor Company is an American multinational automaker, founded by Henry Ford in 1903. One of the most long-standing giants of the motoring industry with an estimated asset wealth of around $256 billion, Ford became a popular household name throughout the UK in the 1960s with the introduction of the Ford Transit, the Ford Escort and the Ford Capri.

How popular is Ford in the United Kingdom?

With the Ford Fiesta consistently winning accolades as the best selling car in the UK, it’s no surprise to hear that in 2018 there were approximately 5.5million Ford cars on the roads by the end of the year.

With a proven track record for good value and sensible, practical driving, along with a dealership just around every corner, Ford has developed a method of sustaining great sales by giving drivers just what they need.

Popular well-priced cars with a sturdy reputation

There’s a Ford car for practically every sensible driver. Actually, there are a few Ford cars for the more daring driver too. Take a look at the history of RS and Cosworth models, both making an impact in the world of rally driving and touring car racing.

While they’re better known for providing family transport that includes the Ka, the Fiesta and the Focus, Ford also produces the lavishly equipped Edge SUV, and also the S-Max and Galaxy people carriers too.

And for something quite a lot less mainstream, Ford deliver some muscle

From a very traditional and mainstream marque, it’s refreshing to see that they still deliver a great big slice of larger than life America—and the latest model Ford Mustang is no exception. If a Mondeo or a Focus isn’t really your thing, and even the RS models aren’t sporty enough, then the new Mustang’s brawny delivery of sleek lines powered by its 5-litre V8 engine could be just the thing. Failing that, the Ford GT supercar with its twin-turbo V6 won’t fail to turn heads. All £420k of it.

How often should a brake caliper need replacing?

Brake calipers are usually very durable. On modern vehicles, it's not uncommon for calipers to last at least 100,000 miles or 10 years. However, if you experience any of the above symptoms, you should have your brakes inspected by a mechanic as soon as possible. Driving with stuck, damaged or faulty brake calipers is very dangerous as it will impact the effectiveness of your braking, meaning your presence on the road is a danger to all other road users.

It’s also important to keep in mind that bad brake calipers can cause excessive wear to the brake discs and pads, so having them repaired or replaced as soon as possible will be better for your wallet in the long-run.

What happens during a brake caliper replacement?

Our certified mechanics will:

• Inspect the brakes and determine if there’s a problem with one or several of the brake calipers. They will also advise if other parts of the braking system need replacing too.

• They will then replace the brake caliper and other parts of the brake, if necessary.

• Bleed the brake system and top up the brake fluid.

• Test drive the car and inspect the brake system again.

• Make any final, necessary adjustments.

What causes a brake caliper to break?

In general, brake pads and rotors wear out and need replacement far more often than calipers. Calipers tend to get damaged when a car is driven with worn-out brake pads or warped rotors. If these components are damaged it can cause the calipers to overheat, wear down or crack.

Calipers can also break if the rubber boot that protects the piston splits. Once this occurs, water and grit will seep into the pistons surface and cause pitting, which can lead to the piston getting stuck or damaged.

When should a brake caliper be replaced?

• If you notice brake fluid on the rims of your wheels.

• If you receive an advisory note regarding brake imbalance.

The law, vehicle regulations and your MOT

The efficiency and balance of brakes is checked on MOT tests, therefore it's important that every component of your brake system is in good condition, including your brake calipers. Because your brakes are arguably the most crucial safety component in your car, your vehicle will fail its MOT if they are not functioning properly or are damaged.
