Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, basic hand tools (socket set, screwdrivers).
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during braking system inspection.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the braking components.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if less than 3mm.
- Check for uneven wear or damage.
Brake Rotors:
- Inspect the rotors for scoring, warping, or excessive wear.
- If damaged, replace or resurface the rotors based on manufacturer specifications.
Calipers:
- Check for proper movement of the caliper piston.
- Ensure caliper slides are lubricated and not seized.

4. Replace Components (if necessary)

If brake pads are worn down:
- Remove old pads and replace them with new ones.
- Use brake lubricant on pad backing and caliper contact points.
If rotors are damaged:
- Remove the rotor and install a new or resurfaced rotor according to specifications.
- Torque rotor bolts to manufacturer-recommended values.

5. Reassemble and Test

Reinstall the caliper over the new pads and secure it with bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to manufacturer specifications.
Reconnect the battery.
