Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Step 1: Open the hood and locate the brake master cylinder.
Step 2: Inspect the brake fluid level. If low, add the recommended brake fluid (DOT 3 or DOT 4, depending on specifications).
Step 3: Secure the cap of the master cylinder after refilling.

3. Inspect for Leaks

Step 1: Visually inspect the brake lines and connections for any signs of fluid leaks.
Step 2: If leaks are found, replace the damaged brake lines or fittings as necessary.

4. Bleed the Brake System

Step 1: Starting from the wheel farthest from the master cylinder (usually the right rear), attach a clear hose to the bleeder screw on the brake caliper.
Step 2: Have an assistant press the brake pedal several times and hold it down.
Step 3: Open the bleeder screw to allow air and fluid to escape, then close it before the assistant releases the pedal.
Step 4: Repeat this process until no air bubbles appear in the fluid, then move to the next wheel (left rear, right front, left front) in the same manner.

5. Replace Worn Components

Step 1: If the brake pads or rotors show significant wear, remove the calipers and replace the pads and/or rotors.
Step 2: Reassemble the calipers and ensure all bolts are torqued to manufacturer specifications.
