Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, C-clamp, jack and jack stands, lug wrench
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Loosen the lug nuts slightly while the car is on the ground.

2. Lift the Vehicle

Use a jack to lift the vehicle and place jack stands under the frame for safety.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Remove Old Brake Pads

Locate the brake caliper and remove the bolts securing it using a socket wrench.
Carefully slide the caliper off the rotor. Support the caliper with a bungee cord or hang it to avoid stressing the brake line.
Remove the old brake pads by sliding them out of the caliper bracket.

4. Inspect and Prepare Components

Inspect the brake rotor for wear and damage. If necessary, resurface or replace.
Clean the caliper bracket and the rotor surface using brake cleaner to remove dust and debris.

5. Install New Brake Pads

Apply a small amount of brake grease to the backing of the new brake pads to prevent noise.
Slide the new brake pads into the caliper bracket, ensuring they are seated properly.
Compress the caliper piston using a C-clamp to allow enough space for the new pads.

6. Reassemble Brake Assembly

Reinstall the caliper over the new brake pads and secure it with the bolts. Torque the bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully lower the vehicle to the ground and then torque the lug nuts to the specified value (typically about 80-100 ft-lbs).
