Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and a brake pad spreader tool.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported with jack stands. Always wear protective gloves and eyewear.

2. Remove Wheel

Loosen the lug nuts slightly while the wheel is still 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. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper mounting bolts using the socket set.
Carefully slide the caliper off the rotor without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and rotor with brake cleaner to remove dust and debris.
Install new brake pads into the caliper bracket, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or uneven wear. If damaged, remove the rotor by unscrewing the rotor retaining screws (if applicable).
Install new rotors by aligning them with the hub and securing them with screws.
Ensure the rotor surface is clean before installing the caliper.

5. Reassemble and Torque

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to the manufacturer's specifications using a torque wrench.
Reattach the wheel, hand-tightening the lug nuts initially.

6. Lower Vehicle and Finalize

Lower the vehicle to the ground and remove the jack stands.
Tighten the lug nuts in a criss-cross pattern to the specified torque.
Pump the brake pedal a few times to seat the pads against the rotor.
