Solution

1. Preparation

Tools Required: Jack stands, lug wrench, brake cleaner, caliper tool, torque wrench, socket set, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Wear safety goggles and gloves.

2. Lift the Vehicle

Loosen the lug nuts on the wheel that requires brake inspection.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel.

3. Inspect Brake Components

Inspect Brake Pads: Remove the caliper bolts and slide the caliper off the rotor. Check the brake pads for uneven wear.
Check Caliper Condition: Ensure the caliper slides freely. If it’s sticking, clean or replace the caliper slides and lubricate them with brake grease.
Examine Rotors: Measure rotor thickness using a micrometer. If warped, they may need resurfacing or replacement.

4. Replace Brake Pads (If Necessary)

Remove the old brake pads by sliding them out of the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads ensuring they match the caliper and are oriented correctly.
Compress the caliper piston using a caliper tool to fit over the new pads.

5. Reassemble and Torque

Reposition the caliper over the new pads and secure it with the caliper bolts. Torque the bolts to the manufacturer's specifications (usually around 23-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test

Lower the vehicle from the jack stands and tighten the lug nuts in a star pattern.
Start the vehicle and pump the brakes a few times to ensure proper contact with the pads.
Test drive the vehicle to assess braking performance.
