Solution

1. Preparation

Park the vehicle on a flat surface and engage the parking brake.
Gather necessary tools and parts.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle depending on the caliper being serviced.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to access the brake caliper.

4. Remove the Caliper

Locate the caliper mounting bolts (usually two).
Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the brake rotor; support it using a bungee cord or wire to avoid stressing the brake line.

5. Inspect and Replace Components

Inspect the caliper for damage or corrosion.
If necessary, replace the caliper with a new one.
Ensure the new caliper comes with new brake pads if it’s part of the service.

6. Reinstall Caliper

Position the caliper back over the brake rotor.
Hand-tighten the mounting bolts, then torque to the manufacturer’s specifications (consult service manual for exact torque values).

7. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern.
