Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is on a level surface and secure with wheel chocks.
Raise the vehicle using a jack and support it with jack stands.

2. Inspect and Replace Brake Pads

Remove Wheel
- Use a lug wrench to loosen and remove the wheel lug nuts.
- Remove the wheel from the hub.
Remove Brake Caliper
- Use a socket set to remove the caliper mounting bolts.
- Carefully slide the caliper off the rotor. Support it using a bungee cord to avoid stress on the brake line.
Remove Brake Pads
- Slide the old brake pads out of the caliper bracket.
- Inspect the caliper bracket for wear; clean if necessary.
Install New Brake Pads
- Apply brake grease to the back of the new pads to reduce noise.
- Insert new brake pads into the caliper bracket.
Reinstall Brake Caliper
- Position the caliper over the new pads and secure it with the mounting bolts.
- Torque bolts to manufacturer specifications (typically between 20-30 ft-lbs).

3. Check and Adjust Brake System

Inspect Brake Calipers
- Check the caliper pistons for smooth operation. Replace calipers if they are sticking.
Check Brake Rotors
- Measure rotor thickness with a micrometer. Replace if below minimum thickness.
- If warped, resurface or replace rotors.
Brake Fluid
- Check brake fluid level and condition. Replace if contaminated or low.

4. Alignment and Suspension Check

Inspect Suspension Components
- Check control arms, bushings, and struts for wear.
- Replace any worn components as needed.
Perform Wheel Alignment
- Use an alignment machine to ensure proper wheel alignment according to specifications.
