Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the brake fluid reservoir cap and inspect fluid level.
2. If fluid is low or contaminated, use a turkey baster to remove old fluid.
3. Refill with fresh brake fluid that meets manufacturer specifications (DOT 3 or DOT 4).
4. Reinstall the cap securely.

3. Inspect Brake Pads and Rotors

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the wheel to access the brake assembly.
3. Inspect brake pads for thickness; replace if less than 3mm.
4. Measure rotor thickness with a micrometer; replace if below minimum specifications.
5. Check for rotor warping or scoring; replace rotors if necessary.

4. Brake Booster Inspection

Sub-steps:
1. Visually inspect the brake booster for any damage or vacuum leaks.
2. Test the brake booster by pressing the brake pedal while the engine is off; it should feel firm.
3. Start the engine and press the pedal; the pedal should drop slightly if the booster is functioning properly.
4. If defective, replace the brake booster following manufacturer guidelines.

5. Final Assembly

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Pump the brake pedal several times to ensure proper pressure.
3. Perform a brake fluid bleed if air has been introduced into the system.
4. Dispose of old brake fluid and any replaced parts responsibly.
