Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety gloves and goggles for personal protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the affected axle.
Secure with jack stands to ensure safety while working.

3. Remove Wheel

Use a socket set to remove lug nuts and take off the wheel.

4. Inspect and Replace Brake Components

A. Brake Rotor Inspection

Remove the brake caliper by unbolting it from the bracket.
Slide the caliper off the rotor and hang it using a bungee cord to avoid straining the brake line.
Inspect the rotor for warping using a dial indicator or straight edge.
If warped, replace the rotor.

B. Brake Pad Inspection

Check brake pads for thickness. If less than 3mm, replace them.
Ensure pads are seated evenly in the caliper bracket.

C. Reassembly

If any components were replaced, install new rotors and pads.
Reattach the brake caliper and torque the bolts to the manufacturer’s specifications (usually around 25-35 ft-lbs).
Reinstall the wheel and torque the lug nuts to manufacturer specifications (typically 75-100 ft-lbs).

5. Final Check

Lower the vehicle and pump the brake pedal to restore brake pressure before driving.
