Solution

1. Preparation

Gather necessary tools and safety gear.
Park the vehicle on a flat surface and engage the parking brake.

2. Remove Wheel

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

3. Inspect and Replace Brake Rotors

Sub-steps:
1. Use a dial indicator to measure the rotor runout; replace if beyond specifications (typically 0.002-0.004 inches).
2. If needed, remove the caliper by unbolting it and hanging it with a wire.
3. Unbolt the rotor from its hub (if applicable) and remove it.
4. Install new rotors, ensuring they are clean and properly seated.
Tools Required: Dial indicator, socket set, brake cleaner.

4. Inspect and Replace Brake Pads

Sub-steps:
1. Check brake pad thickness; replace if under the minimum (typically 3mm).
2. Remove the old pads by sliding them out of the caliper bracket.
3. Lubricate caliper sliding pins and install new pads.
Tools Required: Brake pad spreader, grease.

5. Reassemble and Test

Sub-steps:
1. Reinstall the caliper and torque the bolts to manufacturer specifications.
2. Reattach the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and fully tighten lug nuts in a crisscross pattern.
4. Test the brakes in a safe area to check for improvement.
Tools Required: Torque wrench.
