Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface and use wheel chocks for safety.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Check the brake fluid condition and replace if contaminated or low.
Remove the brake fluid reservoir cap, use a funnel to add new brake fluid (DOT 3 or DOT 4 as specified in the owner's manual) until it reaches the maximum level.

3. Bleed Brake Lines

Tools Required: Brake bleeder kit, clear tubing, container for old fluid.
Start with the brake furthest from the master cylinder (usually the passenger rear).
Attach the clear tubing to the bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times, then hold it down.
Open the bleeder valve to release air and old fluid, then close it before the pedal is released.
Repeat until no air bubbles are visible in the fluid. Move to the next wheel in the order: driver rear, passenger front, and finally driver front.
Ensure to keep the brake fluid reservoir topped up during the process to avoid introducing air.

4. Inspect Brake Components

Tools Required: Socket set, torque wrench.
Remove the wheels to access brake components.
Inspect brake pads for wear; replace if they are below the minimum thickness.
Check rotors for warping or excessive wear; replace if necessary.
Reassemble and torque wheel lug nuts to manufacturer specifications.

5. Test Brake System

Reconnect the battery (if disconnected).
Start the vehicle and pump the brakes to ensure a firm pedal.
Conduct a test drive to confirm braking performance.
