Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, brake cleaner, torque wrench, basic hand tools.
Safely lift the vehicle using a jack and secure with jack stands.
Remove the wheel to access the brake components.

2. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor and suspend it using a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Inspection: Check for uneven wear on the brake pads. Measure thickness and replace if worn beyond specification (typically below 3mm).

3. Inspect and Replace Rotors (if necessary)

Check rotors for any signs of warping or scoring. Use a micrometer to measure rotor thickness.
If rotors are below minimum thickness specifications or damaged, replace with new rotors.
Clean the rotor surface with brake cleaner before installation.

4. Check and Service Calipers

Inspect caliper slide pins to ensure they are lubricated and moving freely. Replace if seized or damaged.
Apply brake grease to the caliper slide pins during reassembly.
Reinstall the caliper over the new brake pads and torque the caliper bolts to manufacturer specifications (typically around 25-30 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Torque the lug nuts to manufacturer specifications (usually around 100-150 ft-lbs).
Pump the brake pedal to ensure proper brake pad seating.
