Solution

1. Preparation

Gather necessary tools and components.
Ensure the vehicle is parked on a level surface and turn off the ignition.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the brake fluid reservoir cap and check fluid level; add manufacturer-recommended brake fluid if low.
2. If fluid is contaminated, proceed to flush the brake system.
3. To flush, connect a brake bleeder kit to the brake calipers.
4. Pump the brake pedal to expel old fluid until it runs clear, ensuring to maintain the fluid level in the reservoir.
Tools Required: Brake bleeder kit, wrench set
Safety Warnings: Do not let brake fluid come into contact with painted surfaces, as it can cause damage.

3. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake calipers and rotors.
2. Inspect the brake pads for wear; replace if thickness is below 3mm.
3. Inspect the rotors for scoring or warping; replace if necessary.
4. Reassemble with new components, ensuring proper torque specifications (typically around 85-90 Nm for caliper bolts).
Tools Required: Socket set, torque wrench
Safety Warnings: Ensure the vehicle is securely supported on jack stands before working underneath.

4. Check Brake Booster and Vacuum System

Sub-steps:
1. Inspect the brake booster for any visible damage or leaks.
2. Check the vacuum line connected to the booster for cracks or disconnections.
3. If the brake booster is faulty, remove it and replace it with a new unit, following manufacturer specifications.
Tools Required: Wrench set, vacuum gauge
Safety Warnings: Disconnect the battery before working on electrical components.
