Diagnostic Steps

1
Inspect brake pads for wear and proper installation.
2
Check brake rotor condition for scoring or warping.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Inspect brake lines for leaks or damage.
5

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a socket set to remove the lug nuts from the wheel.
Carefully take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Inspection:
- Check the thickness of the brake pads; they should be at least 3mm thick.
- Look for uneven wear or glazing.
Replacement:
- If replacement is needed, remove the caliper by unscrewing the caliper bolts.
- Slide the caliper off the rotor and suspend it (do not let it hang by the brake line).
- Remove the old brake pads from the bracket.
- Install new brake pads, ensuring they are properly aligned.
- Reattach the caliper and torque the bolts to manufacturer specifications (typically around 30-40 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are scored or warped, replace them.
Remove the caliper bracket by unscrewing the bolts.
Slide off the rotor from the hub.
Install the new rotor and secure the caliper bracket back on.

5. Lubricate Contact Points

Apply brake grease to the back of the new pads and any sliding surfaces to prevent squeaking.
Ensure no grease gets on the friction surface of the pads or rotors.

6. Reassemble and Test

Reinstall the wheel and tighten the lug nuts in a star pattern to the manufacturer's torque specifications (typically around 76-86 ft-lbs).
Reconnect the negative battery terminal.
Lower the vehicle from the jack stands.
