Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a flat surface and securely lifted using jack stands.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Using a socket set, loosen the lug nuts while the vehicle is on the ground.
Lift the vehicle with a jack and securely place it on jack stands.
Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
If necessary, hang the caliper using a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Compare new brake pads with old ones to ensure they are the correct size.

4. Clean and Lubricate

Clean the caliper bracket and rotor surface using brake cleaner to remove dust and debris.
Lubricate caliper slide pins and the back of the new brake pads with anti-squeal lubricant.

5. Reassemble Components

Insert the new brake pads into the caliper bracket.
Reposition the caliper over the new pads and secure it by tightening the caliper bolts to the manufacturer's specified torque (typically 20-30 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (usually 100-120 ft-lbs).
Reconnect the battery and pump the brake pedal to ensure proper brake function.
