Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Allow the wheels and brakes to cool if recently used.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Jack up the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor.
3. Inspect the brake pads for thickness; replace if worn down to 3mm or less.
4. If replacing, use a brake pad spreader to compress the caliper piston.
5. Install new brake pads and reassemble the caliper.

4. Check and Replace Brake Rotors (if needed)

Tools Required: Torque wrench, brake rotor puller (if stuck)
Sub-steps:
1. Inspect the rotors for scoring or warping; replace if severely damaged.
2. If replacing, remove the rotor by unscrewing retaining screws and pulling it off.
3. Install new rotors, ensuring they are properly seated.

5. Reassemble and Test

Tools Required: Torque wrench
Sub-steps:
1. Reattach the caliper and torque the bolts to manufacturer specifications.
2. Reinstall the wheel and torque the lug nuts in a crisscross pattern.
3. Lower the vehicle and perform a final inspection.
