Solution

1. Preparation

Gather necessary tools and parts.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheels to access the brake components.

2. Inspect and Replace Brake Pads

Remove Brake Calipers
- Use a socket set to remove caliper mounting bolts.
- Carefully slide the caliper off the rotor and support it with a bungee cord to avoid strain on the brake line.
Inspect Brake Pads and Rotors
- Measure the thickness of each brake pad; replace if below manufacturer specifications.
- Check rotors for warping or damage; replace if necessary.
Install New Brake Pads
- Apply brake grease to the back of the new pads to reduce noise.
- Slide new pads into the caliper bracket and ensure proper seating.
Reinstall Brake Calipers
- Position the caliper over the new pads and secure with the mounting bolts. Torque to manufacturer specifications (typically around 25-35 ft-lbs).
Repeat for Other Wheels
- Follow the same steps for all wheels to ensure uniformity.

Inspect Calipers
- If calipers are sticking, clean or replace them as necessary.
Check Suspension and Alignment
- Inspect suspension components for wear or damage; replace as needed.
- Get a professional alignment if necessary.
