Solution

1. Preparation

Gather tools and parts:
- Tools: Socket set, torque wrench, brake cleaner, C-clamp, caliper tool, jack, jack stands, wheel chocks.
- Parts: New brake pads, brake rotors (if necessary), caliper hardware kit.
Ensure the vehicle is on a flat surface, and engage the parking brake.

2. Elevate the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on the affected brakes.
Secure the vehicle on jack stands for safety.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor. Support it with a bungee cord or rope to avoid stressing the brake line.
Use a C-clamp to compress the caliper piston fully into the caliper housing.
Remove the old brake pads from the bracket and inspect for uneven wear.
Install new brake pads, ensuring they fit snugly in the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are warped or scored, remove them by unscrewing the rotor retaining screws (if equipped).
Clean the hub surface with brake cleaner to ensure a proper fit for the new rotor.
Install the new rotor, securing it with screws if applicable.

5. Reassemble the Brake Assembly

Reposition the caliper over the new brake pads and rotor.
Tighten the caliper bolts to the manufacturer’s specifications (typically around 25-35 Nm).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to the specified torque (typically around 110 Nm).

6. Final Checks

Lower the vehicle and remove the jack stands.
Pump the brake pedal several times to ensure proper brake pad seating.
Check brake fluid level and top off if necessary.
