Solution

1. Preparation

Gather tools and parts needed for brake inspection and replacement.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Remove Wheel

Use a jack to lift the vehicle and secure with jack stands.
Remove the wheel lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect: Check the thickness of the brake pads; replace if less than 3mm.
Remove: Unbolt the caliper using a socket wrench; suspend it with a bungee cord to avoid straining the brake line.
Replace: Remove old brake pads from the caliper bracket. Install new pads, ensuring they are oriented correctly.

4. Inspect and Replace Brake Rotors (if necessary)

Remove: Unbolt the rotor from the hub; if stuck, gently tap with a rubber mallet.
Replace: Install new rotors, ensuring they are clean and free of debris. Torque the rotor bolts to manufacturer specifications (typically 90-100 lb-ft).

5. Reassemble Components

Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern to ensure even seating.

6. Final Checks

Lower the vehicle and pump the brake pedal to seat the new pads.
Check brake fluid level and top off if necessary.
