2
Check brake rotors for scoring, warping, or rust buildup.
3
Examine brake calipers for proper operation and any signs of leakage.
4
Inspect brake fluid level and condition in the master cylinder reservoir.
5

Solution

1. Preparation

Gather tools and safety equipment.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheels using a socket set.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using a socket wrench.
- Carefully lift the caliper off the rotor and support it with a bungee cord.
- Inspect brake pads for thickness (minimum thickness should be 3mm).
- If worn, replace with new brake pads.
Brake Rotors:
- Check rotors for any visible scoring or warping.
- If damaged, remove the rotor by unscrewing the rotor retaining screws.
- Replace with new rotors if necessary.

4. Clean and Lubricate

Clean the brake caliper and rotor surfaces with brake cleaner.
Apply brake grease to the back of the brake pads and at the caliper contact points to reduce noise.

5. Reassemble and Test

Reattach the brake caliper and torque the bolts to manufacturer specifications (typically 25-30 Nm).
Reinstall the wheels and lower the vehicle.
Pump the brake pedal several times to seat the brake pads correctly.
