3. What is the main function of a disc brake rotor?

1. To cool the engine
2. To inflate the tires
3. To filter the fuel
4. To provide a surface for brake pads

Which parts are found in brake calipers?

What is the purpose of a caliper in a disc brake?

1. To release the brake pads

4. To cool the rotor

Which component creates friction to slow down the vehicle in a disc brake?

1. Brake pads
2. Rotor
3. Brake fluid
4. Caliper

Where is the brake rotor located in a disc brake system?

1. Under the brake pedal
2. Inside the caliper
3. Behind the wheel
4. Between the brake pads

Brake Caliper Basics

Brake calipers are essential components of the braking system responsible for slowing down or stopping the vehicle when the brakes are applied. How extreme the car, how bigger the brakes? 

What are common problems with calipers?

What is brake fade?

Brake fade is the deterioration of the braking performance due to heat buildup and changes in brake system components. It can happen with both drum and disc brakes. Loss of stopping power, or fade, can be caused by friction fade, mechanical fade, or fluid fade. Brake fade can be significantly reduced by appropriate equipment and materials design and selection, as well as good cooling

Caliper Issues & types of brake pads.

Common problems with brake calipers include sticking, uneven wear, and leaks, which can impact braking performance.

Non-metallic materials - these are made from a combination of various synthetic substances bonded into a composite, principally in the form of cellulose, aramid, PAN, and sintered glass. They are gentle on rotors, but produce a fair amount of dust, thus having a short service life.

Semi-metallic materials - synthetics mixed with varying proportions of flaked metals. These are harder than non-metallic pads, more fade-resistant and longer lasting, but at the cost of increased wear to the rotor/drum which then must be replaced sooner. They also require more actuating force than non-metallic pads in order to generate braking torque.

Fully metallic materials - these pads are used only in racing vehicles, and are composed of sintered steel without any synthetic additives. They are very long-lasting, but require more force to slow a vehicle while wearing off the rotors faster. They also tend to be very loud.

Which tools do you need to work on calipers?

Tools and Equipment

The necessary tools for caliper service include a socket set, brake fluid, brake cleaner, wire brush and a C-clamp for compressing the caliper piston, bike cleaner, paper towel

red rubber grease, brush, torque wrench.

How do you repair a caliper?
Write down the steps.

Removing the Caliper

Start by lifting the vehicle, removing the wheel, and then carefully loosening and removing the caliper bolts to access the brake pads and rotor.

Inspecting and Cleaning

Inspect the caliper for wear, damage, or corrosion, and clean it thoroughly using brake cleaner and a wire brush to remove any debris.

Replacing Brake Pads

Carefully remove the old brake pads and replace them with new ones, ensuring they are properly aligned within the caliper bracket.

Caliper Reassembly

Gently push the caliper piston back using a C-clamp, then reattach the caliper to the bracket and secure it with the caliper bolts.

Brake Fluid and Testing

Top up the brake fluid reservoir as needed, then test the brakes to ensure proper functionality and responsiveness before driving the vehicle. 

But what happens if it all goes wrong?
