Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Gather safety gear including gloves and safety glasses.

2. Jack Up the Vehicle

Use a hydraulic jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
Secure the vehicle on jack stands to ensure stability.
Remove the wheel using a lug wrench.

3. Remove Old Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket set.
Carefully slide the caliper off the brake rotor without disconnecting the brake line.
Remove the old brake pads from the caliper bracket. If they are stuck, gently pry them off with a flat-head screwdriver.

4. Inspect and Clean Components

Inspect the brake rotor for grooves, cracks, or excessive wear. Replace if necessary.
Clean the caliper bracket and the area around the rotor using brake cleaner.
Check the brake hardware (clips and shims) for wear and replace if necessary.

5. Install New Brake Pads

Apply brake grease to the back of the new brake pads to prevent noise.
Position the new brake pads into the caliper bracket.
Reinstall the caliper over the new pads and secure with the caliper bolts. Torque the bolts to the manufacturer's specifications (typically around 25-35 lb-ft).

6. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle to the ground and torque the lug nuts to the manufacturer’s specifications.
Pump the brake pedal a few times to seat the brake pads before driving.
