Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, brake cleaner, caliper gauge.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake components.

2. Remove Brake Pads

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid damaging the brake line.
Remove the old brake pads from the caliper bracket.

3. Inspect and Clean Components

Inspect the brake pads for wear; replace if less than 3mm thickness remains.
Clean the caliper bracket, rotor, and other components with brake cleaner to remove dust and debris.
Check the rotor for damage; if warped or scored, consider resurfacing or replacing.

4. Install New Brake Pads

Apply a thin layer of brake grease to the back of the new brake pads to reduce noise.
Position the new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and tighten the caliper bolts to manufacturer specifications (typically around 25-35 lb-ft).

5. Reassemble and Test

Reattach the wheel and lower the vehicle back to the ground.
Torque the wheel lug nuts to the specified torque (usually 75-100 lb-ft).
Pump the brake pedal several times to seat the pads before driving.
