Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, caliper tool.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent accidental electrical shorts.

2. Wheel Removal

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Brake Pad and Caliper Inspection

Inspect the brake pads for uneven wear and measure their thickness.
Remove the caliper bolts using the appropriate socket.
Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid stressing the brake line.

4. Brake Pad Replacement

If pads are unevenly worn, replace them with a new set that meets OEM specifications.
Clean the caliper bracket and rotor with brake cleaner to remove dust and debris.
Use a caliper tool to compress the caliper piston back into the housing if replacing pads.
Install new brake pads, ensuring they are correctly seated in the caliper bracket.

5. Caliper Reinstallation

Reattach the caliper over the new brake pads and tighten the caliper bolts to manufacturer torque specifications (typically around 20-30 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer specifications (typically 80-90 lb-ft).
Reconnect the battery.
Test the brakes by pressing the pedal a few times to ensure proper engagement before driving.
