Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Inspect and Refill Brake Fluid

Open the hood and locate the brake fluid reservoir.
Check the fluid level; if it's low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
Inspect for leaks around the reservoir and brake lines.

3. Bleed the Brake System

Start by bleeding the brakes to remove any air trapped in the lines.
Use a brake bleeder kit or a clear tube attached to the bleeder valve on each brake caliper.
Begin with the brake farthest from the master cylinder (usually the right rear), open the bleeder valve, and have an assistant press the brake pedal until fluid flows without bubbles.
Close the bleeder valve and repeat for each wheel in the order: right rear, left rear, right front, left front.
Recheck fluid levels in the reservoir and top off if necessary.

4. Inspect and Replace Brake Components

If the issue persists, remove the wheels to access the brake calipers, pads, and rotors.
Inspect the brake pads for thickness; replace them if they are below manufacturer specifications (typically less than 3mm).
Check the rotors for grooves or warping; replace if necessary.
Inspect the brake calipers for proper function; replace if leaking or sticking.

5. Check Master Cylinder

If the pedal still feels soft after bleeding, inspect the brake master cylinder.
Remove the master cylinder from its mounting bracket, taking care to note the orientation and connection points.
Inspect for leaks and internal failure; replace if damaged.
