Solution

1. Preparation

Gather tools and parts needed for brake service.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Repair Brake System

Brake Fluid Check
- Remove the brake fluid reservoir cap.
- If fluid is low, top it off with the manufacturer-recommended brake fluid.
Leak Inspection
- Visually inspect all brake lines and hoses for signs of leaks.
- If leaks are found, replace damaged lines or hoses.
Brake Pad and Rotor Inspection
- Remove the wheel to access the brake assembly.
- Inspect brake pads for wear (less than 1/8 inch remaining is critical).
- Measure rotor thickness; replace rotors if below specification.
Brake Pad Replacement
- If pads are worn, remove the caliper bolts and carefully slide the caliper off the rotor.
- Remove old brake pads and install new ones, ensuring they are properly seated.
- Reinstall the caliper and torque bolts to manufacturer's specifications.

3. Bleed the Brake System

Bleeding Procedure
- Starting from the wheel furthest from the master cylinder, attach a brake bleeder kit or hose.
- Open the bleeder valve while an assistant presses the brake pedal to the floor.
- Close the valve before the pedal is released.
- Repeat until no air bubbles appear in the fluid.
- Check fluid levels and top off as necessary.
