Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Tools Required: Jack stands, wrench set, brake fluid, brake line pressure gauge, and safety goggles.
Safety Warnings: Always wear safety goggles when working on brakes. Ensure the vehicle is secured on jack stands before working underneath.

2. Check Brake Fluid Level

Remove the cap from the master cylinder reservoir.
Inspect the brake fluid level; it should be between the "MIN" and "MAX" indicators.
If low, top off with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).

3. Inspect Brake Lines and Hoses

Visually inspect all brake lines and hoses for signs of wear, cracks, or leaks.
Pay particular attention to connections at the master cylinder, calipers, and wheel cylinders.
If leaks are found, replace the affected line or hose as necessary.

4. Bleed the Brake System

Start at the wheel farthest from the master cylinder (typically the right rear).
Attach a clear hose to the bleeder screw on the brake caliper and place the other end into a container with brake fluid.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder screw slightly to release air and fluid, then close it before your assistant releases the pedal.
Repeat this process until no air bubbles are observed in the fluid, then proceed to the next wheel (left rear, right front, left front).
Ensure to maintain the fluid level in the master cylinder during bleeding.

5. Inspect and Replace Brake Components (if necessary)

If the brake pads or rotors show excessive wear, replace them.
Use a torque wrench to tighten caliper bolts to the manufacturer’s specifications when reassembling.
