Solution

1. Preparation

Tools Required: Floor jack, jack stands, brake fluid, OBD-II scanner, wrench set, brake bleeder kit
Ensure the vehicle is parked on a level surface and the engine is off. Engage the parking brake.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the cap from the master cylinder reservoir.
2. Check the brake fluid level; if low, add the manufacturer-recommended brake fluid (typically DOT 3 or DOT 4).
3. If the fluid is dark or contaminated, proceed to replace it.
4. Using a brake bleeder kit, connect it to the brake bleeder valve on the caliper.
5. Open the bleeder valve and pump the brake pedal to expel old fluid until it runs clear.
6. Close the bleeder valve and refill the master cylinder reservoir as needed.

3. Inspect Brake Components

Sub-steps:
1. Remove the wheels to access the brake components.
2. Inspect brake pads for thickness; replace if worn below the minimum specification (usually 3mm).
3. Check the rotors for warping or scoring; replace if necessary.
4. Ensure calipers are functioning correctly and not seized.

4. Test and Replace Brake Booster (if necessary)

Sub-steps:
1. Start the engine and listen for any hissing noises that may indicate a vacuum leak in the brake booster.
2. If a leak is suspected, disconnect the vacuum line from the brake booster and inspect for damage.
3. Remove the brake booster by unbolting it from the firewall and disconnecting any electrical connectors.
4. Replace with a new brake booster if damaged.
