Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and secured with wheel chocks.
Disconnect the battery for safety during brake system work.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the brake caliper by unbolting it from its bracket.
3. Remove the brake pads from the caliper bracket.
4. Use a brake rotor puller if necessary to remove the rotor.
5. Inspect the rotor for warping by measuring with a dial indicator; replace if warped beyond specifications (usually 0.002 inches).
6. If replacement is needed, install the new rotor, ensuring it is clean and free of contaminants.
Tools Required:
- Socket set
- Brake rotor puller
- Dial indicator

3. Replace Brake Pads

Sub-steps:
1. Install new brake pads into the caliper bracket, ensuring they are properly aligned.
2. Reinstall the brake caliper over the pads and torque the bolts to manufacturer specifications (typically 25-35 ft-lbs).
Tools Required:
- Torque wrench

4. Check and Adjust Wheel Alignment

Sub-steps:
1. Use an alignment tool to check the alignment settings.
2. Adjust as necessary to manufacturer specifications to ensure proper tire wear and handling.
Tools Required:
- Alignment tool

5. Inspect and Repair Suspension Components (if needed)

Sub-steps:
1. Inspect control arms and bushings for wear and damage.
2. Replace any damaged components to maintain proper suspension geometry.
Tools Required:
- Socket set
- Wrench set
