Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the 12V battery to prevent any electrical issues during repairs.

2. Inspect Brake Components

Sub-steps:
1. Remove the wheel using a socket set to access the brake components.
2. Visually inspect brake pads for thickness and any signs of uneven wear.
3. Check the brake rotors for warping or scoring using a dial indicator.
4. If the rotors are warped, they will need resurfacing or replacement.
Tools Required: Socket set, dial indicator, brake pad gauge.

3. Replace or Resurface Brake Rotors and Pads

Sub-steps:
1. If rotors are warped, remove them from the hub using a socket set.
2. If replacing, install new rotors according to manufacturer specifications, ensuring proper torque (typically 75-100 ft-lbs).
3. Replace brake pads and ensure they are installed correctly in the caliper.
4. Reassemble the wheel and tighten lug nuts to the manufacturer’s specification (usually about 100-120 ft-lbs).
Tools Required: Torque wrench, socket set.

4. Wheel Alignment

Sub-steps:
1. If uneven tire wear is detected, perform a four-wheel alignment.
2. Adjust toe, camber, and caster angles to manufacturer specifications.
Tools Required: Alignment machine.
