Solution

1. Preparation

Gather tools and parts required for the repair.
Safety first: Disconnect the battery to prevent accidental activation of the braking system.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Inspection: Remove the brake caliper by unbolting it from the bracket (usually two bolts).
Check the pads for wear; if they are less than 1/4 inch thick, they should be replaced.
Replacement: Slide out the old brake pads and replace them with new ones, ensuring they are seated properly.

4. Inspect and Replace Brake Rotors

Check the rotors for any grooves or scoring; if damaged, replace them.
To replace, unbolt the rotor from the hub (if applicable) and install the new rotor, ensuring it is properly aligned.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads and torque the bolts to manufacturer specifications (usually around 20-30 lb-ft, check specific model).
Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (usually 80-100 lb-ft).

6. Final Checks

Lower the vehicle and reconnect the battery.
Pump the brake pedal to ensure proper engagement of the brake pads and calipers.
