Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Lift the vehicle using a jack and support it with jack stands.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts using a socket wrench.
2. Remove the wheel from the hub.
Tools Required: Socket set, lug wrench.
Safety Warnings: Always use jack stands for support; never rely solely on the jack.

3. Inspect Brake Components

Sub-steps:
1. Remove the brake caliper by unscrewing the caliper bolts.
2. Carefully slide the caliper off the rotor and support it using a bungee cord (do not let it dangle).
3. Inspect brake pads for thickness; replace if less than 3mm.
4. Check rotor surface for grooves or warping.
Tools Required: Socket set, bungee cord.

4. Replace Rotors and Pads (if necessary)

Sub-steps:
1. If rotors are warped, remove the old rotor by unscrewing the retaining screws, if applicable.
2. Install new rotor, ensuring it’s properly seated.
3. Install new brake pads into the caliper bracket.
4. Reattach the caliper over the new pads and rotor.
5. Torque caliper bolts to manufacturer's specifications (typically 25-30 Nm).
Parts Required: New brake pads, new rotors.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten lug nuts.
2. Lower the vehicle and then torque lug nuts to manufacturer's specifications (typically 100-120 Nm).
3. Test brake function and listen for any unusual noises.
Tools Required: Torque wrench.
