Diagnostic Steps

1
Inspect brake pads for wear and tear using a visual inspection.
2
Check brake rotor surfaces for scoring or uneven wear.
3
Examine brake calipers for proper function and ensure they are not sticking.
4
Verify the condition of the brake fluid and ensure it is at the correct level.
5

Solution

1. Preparation

Gather tools and parts necessary for the repair.
Park the vehicle on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts slightly.
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 brake components.

3. Inspect Brake Components

Remove the caliper bolts using a socket wrench.
Carefully lift the caliper off the rotor without disconnecting the brake line.
Inspect the brake pads for thickness; replace if less than 3mm.
Check the rotors for any grooves or scoring; replace if necessary.

4. Clean and Lubricate

Use brake cleaner to clean the brake pads and rotors to remove any dust or debris.
Apply anti-squeal lubricant on the back of the brake pads and to the contact points where the caliper meets the pads.
Ensure that all clips and shims are properly installed and in good condition.

5. Reassemble and Test

Reinstall the caliper and tighten the caliper bolts to the manufacturer’s specified torque (typically around 25-30 lb-ft).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and fully tighten the lug nuts in a criss-cross pattern.
