Solution

1. Preparation

Tools Required: Socket set, jack and jack stands, torque wrench, brake cleaner, safety goggles, gloves.
Safety Warnings: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety gear.

2. Remove the Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack up the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the brake pads for wear; if they are less than 3mm thick, replace them.
5. If replacing, install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotors for scoring or excessive wear. If grooves are visible or the rotor is below the minimum thickness, replace it.
2. Remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
3. Install new rotors, ensuring they are clean and free of grease.

5. Reassemble the Brake Components

Sub-steps:
1. Reattach the caliper over the new brake pads and rotor.
2. Tighten caliper bolts to the manufacturer’s specified torque (usually around 20-30 Nm).
3. Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle.
4. Torque the lug nuts to the specified value (usually around 100-120 Nm).

6. Final Checks

Press the brake pedal a few times to seat the new pads against the rotor.
Check brake fluid levels and top off if necessary.
