Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Tools Required: Socket set, jack, jack stands.
Loosen lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are below the manufacturer's minimum thickness, replace them.
Tools Required: Torque wrench, brake cleaner, soft brush.
Remove the caliper bolts and carefully slide the caliper off the rotor.
If necessary, compress the caliper piston using a caliper tool.
Remove the old brake pads and clean the caliper bracket with brake cleaner.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if needed)

Visually inspect rotors for grooves or warping; replace if necessary.
Tools Required: Rotor puller (if needed).
Remove the rotor by removing any retaining screws or bolts.
Install the new rotor, ensuring it is seated properly.

5. Reassemble Braking System

Slide the caliper back over the new brake pads.
Reinstall the caliper bolts and tighten them to the specified torque value (consult manufacturer specs).
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 battery.
Pump the brake pedal to ensure proper pressure before driving.
