Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Remove the cap from the brake fluid reservoir.
Check the fluid level; if low, top up with the recommended brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Replace the reservoir cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing.
Locate the brake bleeder valves on each brake caliper.
Starting from the furthest brake from the master cylinder (usually the passenger rear), attach the tubing to the bleeder valve.
Open the valve slightly while an assistant presses the brake pedal down and holds it.
Close the valve before the brake pedal is released to avoid air entering the system.
Repeat until no air bubbles are visible in the fluid, and then move to the next brake caliper.
Ensure the brake fluid reservoir remains full during this process.

4. Inspect Brake Components

Remove the wheel to access the brake assembly.
Inspect the brake pads for wear; replace if they are below the manufacturer’s specifications.
Check the rotors for warping or damage; resurface or replace if necessary.
Reassemble the wheel and lower the vehicle.

5. Final Check

Pump the brake pedal several times to restore normal pedal feel.
Test the braking function in a safe area before driving normally.
