Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, brake cleaner, and safety goggles.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.

2. Lift the Vehicle

Use the lug wrench to loosen the lug nuts on the wheel where brake pads will be replaced.
Jack up the vehicle and securely place it on jack stands.
Remove the wheel to access the brake assembly.

3. Remove the Brake Caliper

Use the socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and support it with a bungee cord or rope, avoiding stress on the brake line.

4. Replace the Brake Pads

Slide out the old brake pads from the caliper bracket.
Inspect the caliper bracket slides for wear; lubricate if necessary.
Insert new brake pads into the caliper bracket, ensuring they are properly seated.

5. Reinstall the Brake Caliper

Compress the caliper piston using a brake caliper tool or C-clamp to accommodate the new pads.
Position the caliper back over the new pads and secure it with the mounting bolts, tightening to the manufacturer’s torque specifications (usually around 25-35 ft-lbs).

6. Reassemble and Lower the Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern to ensure even torque.

7. Test the Brakes

Pump the brake pedal several times to ensure the brake pads seat properly.
Check for any leaks around the caliper.
