Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and is secure.
Disconnect the battery for safety.

2. Remove Wheel

Use a lug wrench to loosen wheel lug nuts.
Lift the vehicle with a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket set.
Carefully slide the caliper off the brake rotor and support it using a bungee cord to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket for wear; clean any dust or debris.
Install new brake pads, ensuring they are properly positioned.
Apply anti-squeal grease to the back of the pads if recommended.

5. Reinstall Caliper and Wheel

Reposition the caliper over the new pads and tighten caliper mounting bolts to manufacturer specifications (typically 20-25 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 75-85 lb-ft).

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the brake pads.
Check brake fluid level and top off if necessary.
