Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, torque wrench, caliper gauge.
Raise the vehicle using the jack and secure it on jack stands.
Remove the wheel using the lug wrench.

2. Inspect and Replace Brake Pads

Remove the caliper bolts using the socket set and slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
- Safety Warning: Wear gloves to protect against brake dust.
Measure the thickness of the brake pads using the caliper gauge. If worn below the manufacturer’s specification, replace with new pads.
Apply brake cleaner to the caliper and rotor to remove dust and debris.

3. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for scoring or warping.
If the rotors are damaged, remove the caliper bracket bolts and replace the rotors.
Install new rotors, ensuring they are clean and free of oil. Torque the bolts to manufacturer specifications.

4. Reassemble Braking System

Reinstall the caliper over the new pads and rotor, securing it with the caliper bolts.
Torque caliper bolts to manufacturer's specifications.
Reinstall the wheel and lower the vehicle.

5. Final Check

Pump the brake pedal several times until it feels firm.
Check the brake fluid level in the master cylinder and top off if necessary.
