Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery for safety.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Use the jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench, brake pad spreader.
Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully slide the caliper off the rotor and support it without straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper and hardware; replace if damaged.
5. Install new brake pads in the caliper bracket and ensure they are properly seated.
6. Use a brake pad spreader to compress the caliper piston for reinstallation.

4. Reinstall Caliper and Wheel

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Reinstall the caliper over the new brake pads, ensuring proper alignment.
2. Tighten caliper bolts to manufacturer specifications (typically 20-30 ft-lbs).
3. Place the wheel back on the hub and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to manufacturer specifications (typically 100-150 ft-lbs).

5. Final Checks

Tools Required: Brake cleaner, cloth.
Sub-steps:
1. Clean the rotor surface with brake cleaner to remove any contaminants.
2. Repeat the process on the opposite side if necessary.
3. Reconnect the battery.
