Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal.

2. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper mounting bolts using a socket set.
Carefully slide the caliper off the rotor; do not stretch the brake line.
Inspect the brake pads for wear; replace if less than 3mm thick.
- Tools Required: Socket set, Caliper compression tool.
- Safety Warning: Always support the caliper to avoid damaging the brake line.

4. Clean and Prepare Brake Components

Use brake cleaner to remove dust and debris from the brake rotor and caliper.
Apply anti-squeal grease to the back of the new brake pads and install them.
Ensure that any shims are correctly positioned.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the negative battery terminal.
