Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Check Brake Fluid

Open the hood and locate the brake fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, top off with the manufacturer's recommended brake fluid (DOT 3 or DOT 4).

3. Inspect Brake Lines and Components

Visually inspect all brake lines for leaks or damage.
If leaks are found, replace the damaged lines using a flare wrench.
Check the condition of the brake calipers and pads; replace if worn or damaged.

4. Bleed the Brake System

Start with the wheel farthest from the master cylinder (usually the right rear).
Using a brake bleeder kit or a helper, open the bleeder valve on the caliper.
Have the helper press the brake pedal until fluid flows out, then close the valve before they release the pedal.
Repeat until no air bubbles are visible, then move to the next wheel (left rear, right front, left front).
Ensure the brake fluid reservoir does not run dry during the process to prevent air from entering.

5. Inspect and Replace Brake Booster (if necessary)

If the pedal feels spongy after bleeding, check the brake booster for leaks.
Disconnect the vacuum line and inspect for any signs of damage.
If faulty, remove the brake booster by unbolting it from the firewall and disconnecting the master cylinder; replace with a new unit.
