Solution

1. Preparation

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

2. Remove Brake Pads

Sub-steps:
1. Use a socket set to remove the caliper mounting bolts.
2. Carefully slide the caliper off the rotor and support it without stretching the brake line.
3. Remove the old brake pads from the caliper bracket.

3. Inspect and Clean Components

Sub-steps:
1. Inspect the brake hardware (clips, shims) for wear and replace if necessary.
2. Clean the caliper bracket and rotor surface with brake cleaner to remove debris and dust.
3. Check the caliper piston for any signs of corrosion or damage, and clean if necessary.

4. Replace Brake Pads

Sub-steps:
1. Apply brake grease to the backing of the new pads to prevent noise.
2. Install the new brake pads into the caliper bracket.
3. Compress the caliper piston using a caliper tool to accommodate the new pads.

5. Reassemble Braking System

Sub-steps:
1. Carefully slide the caliper back over the new pads.
2. Reinstall and torque the caliper mounting bolts to the manufacturer’s specification (usually 25-30 Nm).
3. Reinstall the wheel and torque the lug nuts to the recommended specification.

6. Test Brake System

Sub-steps:
1. Lower the vehicle and pump the brake pedal several times to seat the pads.
2. Check the brake fluid level and top off if necessary.
