Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, c-clamp, brake cleaner, torque wrench.
Raise the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

2. Remove Brake Caliper

Sub-steps:
1. Locate the caliper mounting bolts and remove them using a socket wrench.
2. Carefully slide the caliper off the brake rotor and support it with a bungee cord or rope to avoid stress on the brake line.

3. Remove Old Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket (they may slide out or need to be pried out gently).
2. Inspect the caliper bracket for wear and clean it with brake cleaner.

4. Install New Brake Pads

Sub-steps:
1. Apply a thin layer of brake grease to the back of the new brake pads to reduce noise.
2. Slide the new brake pads into the caliper bracket.

5. Compress Brake Caliper Piston

Sub-steps:
1. Using a c-clamp, compress the caliper piston back into its housing to make room for the new pads.
2. Ensure the piston is fully retracted before proceeding.

6. Reinstall Brake Caliper

Sub-steps:
1. Slide the caliper back over the new brake pads.
2. Reinstall and torque the caliper mounting bolts to the manufacturer’s specification (typically around 20-25 ft-lbs).

7. Reassemble and Lower Vehicle

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts in a star pattern to the manufacturer’s specification (typically around 76 ft-lbs).
