Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Wear appropriate safety gear (gloves and goggles).

2. Inspect and Replace Brake Fluid

Step 1: Locate the master cylinder reservoir. Remove the cap.
Step 2: If the fluid is dirty or moisture-laden, drain the old fluid by opening the bleeder screws on the brake calipers, starting with the wheel farthest from the master cylinder.
Step 3: Replace with fresh brake fluid as specified by the manufacturer (DOT 3 or DOT 4).
Tools Required: Brake fluid, wrench for bleeder screws, container for old fluid.

3. Bleed Brakes

Step 1: Have an assistant pump the brake pedal several times and hold it down.
Step 2: Open the bleeder screw on the farthest caliper to allow air and old fluid to escape. Close the screw before the pedal is released.
Step 3: Repeat the process on each wheel in the following order: right rear, left rear, right front, left front.
Step 4: Check the fluid level in the master cylinder frequently and top off as needed.
Tools Required: Brake bleeder kit or clear tubing and a container.

4. Inspect Brake Components

Step 1: Remove the wheel to access the brake caliper.
Step 2: Inspect brake pads for thickness; replace if they are worn down.
Step 3: Check rotors for warping or excessive wear; replace if necessary.
Tools Required: Jack and jack stands, lug wrench, caliper tool.

5. Reassemble and Test

Step 1: Reinstall the wheel and lower the vehicle.
Step 2: Start the vehicle and pump the brake pedal to ensure a firm feel.
Step 3: Perform a test drive to confirm proper brake function.
