Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety glasses and gloves to protect from brake dust and fluids.

2. Inspect and Refill Brake Fluid

Remove the master cylinder reservoir cap.
Check brake fluid level; if low, fill it with the recommended brake fluid (DOT 3 or DOT 4).
Replace the cap securely after refilling.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, clear tubing, container for old brake fluid.
Start at the wheel farthest from the master cylinder (usually passenger rear).
Attach the clear tubing to the bleeder screw on the brake caliper.
Open the bleeder screw and have an assistant slowly press the brake pedal several times, then hold it down.
Close the bleeder screw before the assistant releases the pedal to prevent air from entering.
Repeat this process until no air bubbles are seen in the fluid being bled.
Move to the next wheel (driver rear, passenger front, driver front) and repeat until all brakes are bled.
Check fluid level in the master cylinder frequently during bleeding to avoid running low.

4. Inspect Brake Components

Remove the wheel to access brake components.
Inspect brake pads for wear; replace if they are below the manufacturer’s minimum thickness.
Check rotors for grooves or warping; replace if necessary.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle if raised.
Test the brake pedal feel and ensure it feels firm.
Take the vehicle for a short test drive to verify brake performance.
