Solution

1. Preparation

Gather necessary tools and safety equipment.
Ensure vehicle is parked on a level surface and engage the parking brake.

2. Wheel Removal

Tools Required: Socket set, torque wrench, jack, jack stands.
Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts from the wheel using a socket wrench.
Take off the wheel to access the brake components.

3. Brake Pad Inspection

Visually inspect the brake pads for wear indicators.
Measure the thickness of the brake pads using a caliper.
- Desired Thickness: Replace if less than 1/8 inch.
Check for any uneven wear or damage to the pads.

4. Brake Pad Replacement (if necessary)

Tools Required: Brake caliper tool, socket set, anti-squeal lubricant.
Remove the caliper bolts and carefully lift the caliper away from the rotor.
Support the caliper with a bungee cord or similar to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply anti-squeal lubricant to contact points.
Install new brake pads, ensuring they are positioned correctly.
Compress the caliper piston using a brake caliper tool to accommodate the new pads.
Reattach the caliper and torque the caliper bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the manufacturer’s torque specifications.
Repeat for the other side if necessary.
