Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted with jack stands.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Remove the master cylinder cap and inspect the fluid level. If low, top up with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
2. If fluid is dark or contaminated, perform a brake fluid flush.
3. Bleed the brake system to remove air bubbles.
Tools Required: Brake fluid, funnel, brake bleeder kit.

3. Check and Replace Brake Booster

Sub-steps:
1. Inspect the brake booster for physical damage and listen for vacuum leaks.
2. Disconnect the vacuum hose and check for blockages.
3. If defective, remove the brake booster by unbolting it from the firewall and disconnecting the master cylinder.
4. Install the new brake booster, ensuring all connections are secure and reattach the master cylinder.
Tools Required: Socket set, screwdrivers.

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake caliper and pads.
2. Inspect brake pads for thickness; replace if worn below 3mm.
3. Check rotors for warping or grooves; resurface or replace if necessary.
4. Reassemble the brake components and wheel.
Tools Required: Jack, jack stands, socket set, torque wrench.
