A crucial component of your disc brake system that aids in vehicle slowing is the brake caliper. It deteriorates over time, much like other braking components do.
However, because they are essential to keeping you safe, you should swap out a worn-out brake caliper as soon as possible.
It raises the question: How Long Do Bentley Brake Calipers Last? What are the reasons behind their failure?
Later on, we’ll talk about the signs of brake caliper damage and even emphasize the best technique to maintain them.
What Is A Brake Caliper?
A brake caliper is a component of your car’s disc braking system, including brake pads and hydraulic pistons.
When you apply the brakes, friction is created by pistons within the brake caliper pressing your brake pads on the disc brake rotors. And your car slows down as a result of the friction force.
Many cars, especially Bentley, have a brake drum for the back brake and a brake disc or brake rotor up front.
Instead of braking calipers, the rear drum brakes would use pistons inside the wheel cylinder. The brake shoes are pushed up against a drum that spins along the wheel.
Types of Bentley Brake Calipers
Brake calipers play a crucial role in the braking system, housing the brake pads and facilitating the clamping force necessary for stopping the vehicle. While the specific types of Bentley brake calipers may vary based on the model and year, here is provided information on some common types found in Bentley vehicles:
- Fixed Calipers: Fixed calipers, also known as piston calipers, are commonly used in high-performance vehicles like Bentleys. They feature pistons on both sides of the rotor, which apply equal pressure to the brake pads. Fixed calipers provide excellent braking performance, improved pedal feel, and reduced brake fade.
- Floating Calipers: Floating calipers, also called sliding calipers, are a more straightforward design than fixed calipers. They have a single piston on one side of the rotor and rely on the caliper bracket to slide and apply pressure to the brake pads. Floating calipers are generally more affordable and easier to maintain but may not perform as well as fixed calipers.
- Multi-Piston Calipers: Bentley’s high-performance models often feature multi-piston calipers. These calipers have multiple pistons on each side of the rotor, typically arranged in a radial pattern. Multi-piston calipers enhance braking power, improve heat dissipation, and provide better control over brake pad pressure distribution. This design allows for more precise modulation of the braking force.
- Ceramic Composite Calipers: In some high-end Bentley models, you may find ceramic composite brake calipers. These calipers are made from a lightweight ceramic material which offers several advantages, such as reduced weight, improved braking performance, and superior heat resistance. Ceramic-composite calipers are designed to withstand extreme conditions and provide exceptional stopping power.
It’s important to note that Bentley continuously evolves its brake caliper designs, and specific models may feature unique or proprietary calipers to cater to their performance and luxury standards.
How Long Do Brake Calipers Last?
Since disc brake calipers are durable brake parts, they should last as long as your car. Realistically, your brake calipers endure between 75,000 and 100,000 miles or ten years.
It is a rough estimate that does not apply to all vehicles.
Your brake calipers’ lifespan is also affected by the following:
- Road Conditions
- How you drive
- environmental factors, including the weather
- And more
However, there must be a cause for the initial wear and tear on your brake calipers.
Below you may know why and how your Bentley brake calipers get damaged.
How Brake Calipers Get Damaged
The brake calipers within the brake disc and your brake pads create friction when you use the brakes. The kinetic energy that drives your moving vehicle is then transformed into thermal energy, heat, by the frictional force.
Your brake calipers’ temperature naturally rises quickly as a result.
Additionally, when you stop applying the brakes, the disc brake calipers cool rapidly.
Corrosion starts to build on the inside and outside of the brake calipers due to frequent heating and cooling cycles.
This corrosion produces a rough surface on the caliper, which leads to the following:
- brake piston seal abrasive wear
- A brake cylinder chamber with a piston becoming stuck and seizing up
- Uneven braking performance
The debris that the environment deposits on the brake calipers can also wear them down and negatively impact how well they work.
Now that you know the cause of brake caliper failure, let’s examine the warning signs of faulty brake calipers.
What Are The Signs And Symptoms Of A Faulty Brake Caliper?
Here are some signs of a damaged brake caliper that you should be on the lookout for:
Unusual Sounds When Braking
When pressing the brake pedal, if any wheel makes a screeching or frictional sound, you may have brake calipers that must be repaired.
The brake calipers on your car may be jammed, and the brake cylinder bores may become blocked with pistons. The brakes then lose some of their effectiveness, which leads to you losing control of the car.
These squealing sounds may indicate that a brake pad’s backing plate has become exposed.
If this occurs, have a licensed mechanic visit your home to check your brakes or take your vehicle to an auto repair shop. They will try to identify if there is a problem with the brake caliper installation, brake piston, friction material in the brake pads, or any other braking concerns.
After an inspection, the mechanic could advise replacing the brake caliper, the brake rotor, the brake pads, or another braking component to eliminate the noise.
Leaky Brake Fluid
Corroded calipers could swiftly wear away your brake piston’s rubber seal. That frequently results in brake fluid leaks.
The level of brake pressure which can be applied decreases with the brake fluid levels. And if the leaks get out of control, your hydraulic braking system can stop working.
If you notice that your brakes appear to be leaking, have a qualified mechanic examine your brakes.
A mechanic will examine your brake system to see whether you require caliper piston replacement, brake fluid flushing, master cylinder repair, and other brake work.
Your Car Veers To The Side
A car with damaged brake calipers may pull to one side when braking.
That typically occurs when a piston in faulty brake calipers becomes impervious to the wheel rotor and cannot move freely.
As a result, when you apply the brakes, the car veers to the side with more traction. The jammed brake caliper causes the car to veer to the side when you let up on the brakes.
It is advised that a mechanic examines your brake system in this situation to look for brake difficulties such as rusted calipers, worn-out brake pad friction material, stuck-up pistons, or issues with the brake line or brake hose.
Uneven Brake Pad Wear
To slow down your car, remember that your brake pads make contact with the wheel rotor.
Therefore, if your brake caliper is rusted or broken and cannot move freely, it may apply uneven pressure to the brake pads. As a result, an uneven wear pattern may develop in the brake pads on either side of the car.
To be safe, get the brake disc system back on track by replacing or fixing the brake calipers, resurfacing the rotors, or changing the brake pads after having a brake system diagnosis performed by a licensed mechanic.
And only make sure they: when you hire a skilled mechanic.
- Are ASE-certified
- Utilize brake service tools and replacement parts of the highest caliber.
- And extend a service guarantee to you.
Maintenance Tips for Bentley Brake Calipers
Proper maintenance of your Bentley brake calipers ensures optimal performance and safety. Here are some maintenance tips to keep your Bentley’s brake calipers in excellent condition:
- Regular Inspection: Conduct regular visual inspections of the brake calipers to check for any signs of damage or wear. Look for leaks, cracks, or signs of corrosion on the caliper body. If you notice any issues, consult a qualified technician for further assessment and repair.
- Brake Fluid Check: Regularly check the brake fluid level and ensure it is at the recommended level. Low brake fluid can affect the caliper’s performance and lead to braking inefficiencies. If necessary, top up the brake fluid following the manufacturer’s guidelines.
- Brake Pad Inspection: Inspect the brake pads for wear and replace them when necessary. Worn-out brake pads can stress the calipers more, leading to potential damage. Follow the manufacturer’s recommendations regarding pad replacement intervals.
- Cleaning and Lubrication: Clean the brake calipers regularly to remove dust, debris, and road grime. Use a soft brush and brake cleaner to clean the calipers thoroughly. Apply a thin layer of high-temperature brake lubricant to the caliper pins and sliding surfaces to ensure smooth operation.
- Professional Servicing: Schedule regular maintenance visits with a certified Bentley technician experienced in servicing your specific model. They have the expertise to diagnose any potential issues with the brake calipers and address them effectively.
Proper maintenance and timely repairs are essential to keep your Bentley’s brake calipers functioning optimally. Neglecting maintenance can compromise your vehicle’s braking performance and, more importantly, your safety.
How Much Does Brake Caliper Replacement Cost?
Alternatively to being loaded, brake caliper replacement can be friction ready.
The brake calipers for friction-ready brakes do not already have pads inside them. They are hence more affordable. You can purchase friction-ready brake calipers for cars for under $100. Furthermore, larger vehicles may incur a cost of several hundred dollars.
On the other hand, you should prepare to pay $100 to $500 for a replacement brake caliper if you want one supplied with brake pads already attached.
