Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles for protection.

2. Check Brake Fluid Level

Open the hood and locate the brake master cylinder.
Inspect the fluid level; if it’s below the recommended level, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Inspect for Leaks

Visually inspect the brake lines from the master cylinder to the calipers for any signs of leakage.
If leaks are found, replace the damaged brake lines or calipers as necessary.

4. Bleed the Brake System

Use a brake bleeder kit and a helper, if available.
Start at the wheel farthest from the master cylinder (typically the right rear wheel).

Attach the bleeder hose to the bleeder valve on the brake caliper.
Have your helper press the brake pedal several times and hold it down.
Open the bleeder valve to release air and fluid, then close it before your helper releases the pedal.
Repeat until no air bubbles are visible in the fluid, then move to the next wheel (left rear, right front, left front).

5. Inspect and Replace Brake Pads/Rotors (if necessary)

Remove the wheel and inspect the brake pads and rotors.
If the pads are worn below the minimum thickness, replace them.
Replace rotors if they are scored or below the minimum thickness specifications.

6. Test Brake Booster

With the vehicle off, pump the brake pedal several times to deplete vacuum.
Start the engine and press the brake pedal; it should feel firmer. If not, replace the brake booster.
