Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to avoid accidental electrical discharge.

2. Inspect and Replace Brake Components

Inspect Brake Pads and Rotors
- Remove the wheel covering the affected brake assembly using a socket set.
- Visually inspect brake pads for uneven wear; replace if thickness is below manufacturer's specifications.
- Check rotors for grooves or warping and replace if necessary.
Replace Brake Pads
- Remove caliper bolts using a socket set.
- Carefully slide the caliper off the rotor, supporting it with a bungee cord to avoid strain on the brake line.
- Remove old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.
- Reinstall the caliper and torque bolts to manufacturer's specifications.

3. Caliper Check and Replacement (if necessary)

Inspect Caliper Functionality
- Push the caliper piston back using a brake caliper tool.
- Check for smooth operation; if it sticks, consider replacement.
- If replacement is necessary, remove the caliper and install a new one, ensuring proper alignment and torque.

4. Alignment Correction

Perform Wheel Alignment
- After resolving brake issues, take the vehicle to a professional alignment shop.
- Ensure that camber, caster, and toe are adjusted to manufacturer specifications for optimal handling.
