Solution

1. Preparation

Gather Tools: Collect necessary tools including a brake bleeder kit, socket set, and a torque wrench.
Safety Precautions: Park the vehicle on a level surface, engage the parking brake, and wear safety glasses.

2. Brake Fluid Inspection

Check Fluid Level: Remove the cap from the brake fluid reservoir and check the fluid level. If low, top off with the recommended brake fluid (DOT 3 or DOT 4).
Inspect for Contaminants: Look for signs of contamination (dark or dirty fluid) and replace if necessary.

3. Brake Component Inspection

Remove Wheel: Use a jack to lift the vehicle and remove the wheel using a socket set.
Inspect Brake Pads and Rotors: Check brake pads for thickness and ensure rotors are not warped or excessively worn. Replace if necessary.

4. Brake Bleeding Procedure

Locate Bleed Screws: Identify the bleed screws on each brake caliper.
Bleed Brakes: Follow these sub-steps:
1. Attach a clear tube to the bleed screw and place the other end in a container.
2. Have an assistant press the brake pedal several times and hold it down.
3. Open the bleed screw to release fluid and air, then close it while the pedal is still pressed.
4. Repeat until clear fluid is seen without air bubbles, then move to the next caliper.

5. Reassemble and Test

Reinstall Wheels: Replace the wheels and lower the vehicle.
Test Brakes: Start the engine and press the brake pedal to ensure it feels firm and responsive.
