Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface.
Disconnect the battery.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner
Safety glasses and gloves

2. Remove Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper mounting bolts using a socket set.
Carefully lift the caliper off the rotor and support it with a bungee cord to avoid damaging the brake line.
Remove the old brake pads from the caliper bracket. Check for uneven wear.
If worn, install new brake pads, ensuring they are properly oriented.
Reattach the caliper and torque the mounting bolts to the manufacturer's specifications.

4. Inspect and Resurface or Replace Rotors

Check the brake rotors for any scoring or warping. Use a micrometer to measure rotor thickness.
If warped or damaged, remove the rotors by unscrewing the retaining screws (if equipped) and sliding them off the hub.
Either resurface the rotors or replace them with new ones, ensuring they meet OEM specifications.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands.
Torque the lug nuts to the manufacturer's specifications in a criss-cross pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal until it feels firm.
Check brake fluid level and add if necessary.
