Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the ignition is off.
Put on safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Check the master cylinder reservoir for the brake fluid level.
If the fluid is low, fill it to the recommended level with the manufacturer-specified brake fluid (DOT 3 or DOT 4).
Inspect fluid for contamination; if dirty, proceed to flush the system.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, container for old fluid
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder kit to the brake caliper bleeder screw.
Have an assistant press the brake pedal while you open the bleeder screw, allowing air and fluid to escape.
Close the screw before releasing the pedal, then repeat until no air bubbles are present.
Move to the next wheel following the sequence (right front, left front, then left rear).

4. Inspect Brake Components

Tools Required: Socket set, torque wrench, brake cleaner
Remove the wheel to access the brake components.
Inspect the brake pads for thickness; replace if worn below 3mm.
Check the rotors for warping or scoring; machine or replace as necessary.
Examine the brake calipers for sticking or leaks; replace if damaged.

5. Test Drive and Final Inspection

After reassembly, perform a test drive to ensure proper brake function.
Check for any warning lights and ensure the pedal feels firm.
