•Allow the brakes to cool before inspection.

Symptoms

•Squeaking or squealing noise when brakes are applied
•Reduced braking performance
•Brake pedal feels spongy or less responsive
•Vibration or pulsation in the brake pedal
•Visible dust or debris on brake components

Diagnostic Steps

1
Inspect brake pads for wear: Measure the thickness of the pads to determine if they need replacement.
2
Check brake rotors for warping: Use a dial gauge to measure rotor runout or visually inspect for scoring.
3
Examine brake calipers: Look for signs of leakage or stuck caliper pistons.
4
Inspect brake hardware: Check for missing or damaged clips, shims, or anti-rattle springs.
5
Clean brake components: Remove dust, dirt, and debris from pads, rotors, and calipers.

Solution

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench, socket set
Safely lift the vehicle and remove the wheels using the lug wrench.

2. Inspect and Replace Brake Pads

Remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it on a suspension component (do not hang by the brake line).
Remove the old brake pads from the caliper bracket.
Check the caliper slide pins for lubrication; clean and re-grease if necessary.
Install new brake pads into the caliper bracket, ensuring they are oriented correctly.

3. Check and Replace Brake Rotors (if necessary)

If the rotors are worn or warped, remove them from the hub by unscrewing the retaining screws or bolts.
Clean the hub surface to ensure proper contact with the new rotor.
Install new rotors, securing them with the retaining screws or bolts to the manufacturer's torque specifications.

4. Reassemble Brake Components

Reinstall the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer's torque specifications.
Repeat the process for the other side if necessary.

5. Final Inspection and Reinstallation

Recheck all components and ensure everything is properly secured.
Reinstall the wheels and lower the vehicle to the ground.
Tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications.
