Solution

1. Preparation

Gather tools and materials required for the repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Components

Brake Pads and Rotors:
1. Remove the wheel on the affected side using a socket set.
2. Inspect the brake pads for wear; replace if less than 3mm thick.
3. Check the brake rotor for grooves or warping; replace if necessary.
4. Reinstall the new pads and rotor, ensuring proper alignment and secure with specified torque (typically 75-90 ft-lbs for caliper bolts).
Caliper Inspection:
1. Remove the caliper from the bracket by loosening the caliper bolts.
2. Inspect caliper slides for rust or debris; clean and lubricate as necessary.
3. Check the caliper piston for proper movement; replace if stuck.

3. Alignment Check

Visually inspect suspension components for wear or damage, focusing on control arms and bushings.
If any components are damaged, replace them using a socket set and torque to the manufacturer's specifications.
Take the vehicle to a professional alignment shop for a full alignment to ensure proper handling.

4. Brake Fluid Inspection

Check brake fluid level in the master cylinder; top off with DOT 3 or DOT 4 fluid as needed.
If fluid is dark or contaminated, perform a brake fluid flush.

Tools Required:

Socket set
Torque wrench
Brake cleaner
Lubricant for caliper slides
Brake pad spreader tool (optional)
