Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

Step 1: Remove the brake fluid reservoir cap.
Step 2: Use a turkey baster to remove old brake fluid from the reservoir.
Step 3: Refill the reservoir with fresh brake fluid (DOT 4 recommended).
Tools Required: Turkey baster, brake fluid.

3. Bleed Brake System

Step 1: Start at the wheel farthest from the master cylinder (right rear).
Step 2: Have an assistant pump the brake pedal several times and hold it down.
Step 3: Open the bleeder valve on the brake caliper to allow air and old fluid to escape; close the valve once fluid flows.
Step 4: Repeat the process for the left rear, right front, and then left front brakes.
Step 5: Continuously check the fluid level in the reservoir and refill as necessary.
Tools Required: Brake bleeder kit, wrench for bleeder valves.

4. Inspect Brake Components

Step 1: Remove the wheel to access the brake caliper and rotor.
Step 2: Inspect the brake pads for wear; replace if less than 3 mm thickness.
Step 3: Check the condition of the brake rotors; replace if warped or excessively worn.
Tools Required: Socket set, torque wrench.

5. Test Brake Booster

Step 1: With the engine running, depress the brake pedal to check for a firm feel.
Step 2: If the pedal feels soft, the brake booster may need replacement.
Tools Required: Basic hand tools for removal and installation.
