Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench.
Lift the vehicle and securely support it on jack stands.
Remove the wheels using the lug wrench.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Use a dial indicator to measure rotor runout and check for warping.
2. If warped, remove the brake caliper using a socket set and hang it securely using a bungee cord.
3. Remove the brake rotor by unscrewing any retaining screws or clips.
4. Install new rotors, ensuring they are clean and properly aligned. Torque bolts to manufacturer specifications (usually around 80-100 Nm).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; if worn below 3mm, replace them.
2. Remove the old pads from the caliper bracket.
3. Install new brake pads ensuring they are seated properly in the caliper bracket.
4. Apply brake grease to the pad backing to prevent squeaking.

4. Reassemble and Test

Sub-steps:
1. Reattach the brake caliper over the new pads and torque the caliper bolts to manufacturer specifications (typically around 30-40 Nm).
2. Reinstall the wheels and lower the vehicle.
3. Torque wheel nuts to the manufacturer’s specification (usually 120-140 Nm).
