Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Brake Fluid

Step 1: Remove the brake fluid reservoir cap.
Step 2: Check the fluid condition; if dark or contaminated, proceed to flush and replace.
Step 3: Use a brake fluid bleeder kit to remove old fluid from the system.
Step 4: Refill the reservoir with fresh brake fluid (DOT 4 or as specified by manufacturer).
Step 5: Reconnect the reservoir cap securely.

3. Check and Replace Brake Components

Step 1: Remove the wheel to access the brake components.
Step 2: Inspect the brake pads for wear; replace if thickness is below the manufacturer's specification.
Step 3: Inspect the brake rotors for scoring or warping; replace if necessary.
Step 4: Check the brake caliper for proper operation; replace if sticky or leaking.
Step 5: Reassemble the wheel and lower the vehicle.

4. Brake Booster Test and Replacement

Step 1: If the brake booster is suspected, check for vacuum leaks in the hose.
Step 2: To test, depress the brake pedal several times to expel air, then start the engine; the pedal should drop slightly.
Step 3: If it does not drop, the brake booster may require replacement.
Step 4: Remove the brake booster by disconnecting the vacuum line and unbolting it from the mounting points.
Step 5: Install the new brake booster and connect the vacuum line.
