Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Check and Top Off Brake Fluid

Tools Required: Brake fluid (DOT 3 or DOT 4), clean cloth.
Remove the master cylinder cap and check the brake fluid level.
If low, add the appropriate brake fluid until it reaches the recommended level.
Replace the cap securely.

3. Inspect Brake Lines and Components

Tools Required: Wrench set, socket set.
Visually inspect all brake lines and connections for leaks or damage.
Tighten any loose connections. Replace any damaged lines or fittings.

4. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench, clear tubing.
Start with the wheel farthest from the master cylinder (usually the right rear).
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve on the brake caliper to release air and fluid until the pedal sinks to the floor.
Close the valve, and have the assistant release the pedal.
Repeat this process until no air bubbles are visible in the fluid.
Move to the next wheel in the sequence: left rear, right front, left front.

5. Inspect and Replace Brake Pads if Necessary

Tools Required: Jack and jack stands, socket set, torque wrench.
Remove the wheel and inspect brake pads for wear.
If pads are worn below the minimum thickness, replace them with new pads as per manufacturer specifications.
Reassemble the wheel and torque the lug nuts to the manufacturer's specifications.
