Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the engine is off.
Gather necessary tools and materials.
Wear safety gloves and goggles.

2. Check Brake Fluid

Tools Required: Brake fluid, funnel
Remove the master cylinder cap and inspect the brake fluid level.
If low, fill with the recommended brake fluid type (DOT 3 or DOT 4).
Reinstall the cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clean rags
Sub-steps:
1. Begin with the wheel farthest from the master cylinder (usually the right rear).
2. Attach the bleeder kit to the brake bleeder valve on the caliper.
3. Have an assistant pump the brake pedal several times and hold it down.
4. Open the bleeder valve to release air and fluid. Close the valve before releasing the pedal.
5. Repeat until no air bubbles are visible in the fluid.
6. Move to the next wheel (left rear, right front, left front) and repeat.

4. Inspect and Replace Brake Components

Tools Required: Socket set, torque wrench
If fluid leakage or wear is found:
1. Remove the wheel to access the brake assembly.
2. Inspect brake pads and rotors for damage; replace if necessary.
3. Check brake lines for kinks or damage; replace if needed.
4. Reassemble and torque all components according to the manufacturer’s specifications.

5. Test the Brake System

After bleeding and any necessary replacements, perform a brake test.
Ensure the pedal feels firm and responsive.
Check for leaks and recheck fluid levels.
