Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is on a level surface and park it securely.
Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench, brake caliper tool, brake cleaner, and safety glasses.
Safety Warnings: Always wear safety glasses when working on brakes and ensure the vehicle is securely lifted before working underneath.

2. Remove Wheel

Loosen lug nuts slightly while the wheel is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Check the brake pads and rotors for wear patterns.
If pads are worn unevenly, check caliper movement by removing the caliper.
Inspect the caliper slides and ensure they are clean and lubricated. If they are seized, they should be replaced.

4. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket wrench and lift the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Apply brake grease to the back of the new pads and install them.
Compress the caliper piston using a brake caliper tool to fit over the new pads.

5. Reassemble Components

Reattach the caliper over the new pads and secure it with the caliper bolts, torquing them to the manufacturer specifications (usually around 20-25 ft-lbs).
Replace the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer's specifications (around 150-175 ft-lbs).
Pump the brake pedal several times to ensure proper caliper function and pad seating.
