2
Examine brake rotors for scoring, warping, or uneven wear.
3
Check brake calipers for proper operation and signs of leakage.
4
Inspect brake fluid levels and quality; look for contamination.
5

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves for protection.

2. Remove Wheel Assembly

Tools Required: Socket set, jack and jack stands.
Loosen the 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.

3. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor; do not disconnect the brake line.
Inspect the brake pads for wear; replace if they are below the minimum thickness (typically 3mm).
Sub-steps:
- If replacing, compress the caliper piston using a caliper tool to allow space for new pads.
- Install new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or uneven wear. If damaged, replace the rotor.
Tools Required: Torque wrench.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and free from grease.
Sub-steps:
- Torque the rotor screws to the manufacturer’s specifications.

5. Reassemble and Bleed Brakes

Reinstall the caliper over the new brake pads and secure it with bolts.
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts fully in a star pattern.
Bleed the brake system to remove any air; ensure brake fluid is topped off to the appropriate level.
