Solution

1. Preparation

Gather tools and materials required for the brake service.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect Brake Pads

Remove the wheel using a lug wrench.
Inspect brake pads for thickness; replace if they are worn below the manufacturer's specifications (typically 3mm or less).
Tools Required: Lug wrench, socket set, caliper tool.

3. Check Brake Rotors

Measure rotor thickness with a micrometer; replace if below minimum specification.
Inspect for warping using a dial indicator; if warped, resurface or replace the rotors.
Tools Required: Micrometer, dial indicator, rotor cutting tool (if resurfacing).

4. Inspect Brake Fluid

Remove the brake fluid reservoir cap and check fluid level and condition. Replace fluid if dirty or contaminated.
Tools Required: Brake fluid tester, clean cloth.

5. Test Calipers

Inspect caliper operation by checking for sticking or binding. Replace if necessary.
Ensure caliper slides are lubricated and functioning properly.
Tools Required: Brake caliper tool, grease.

6. Reassemble and Reinstall Components

Reinstall any components removed during inspection and repair.
Torque wheel lug nuts to the manufacturer's specifications (usually around 100-150 ft-lbs).
Tools Required: Torque wrench.
