Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety glasses and gloves.

2. Check Brake Fluid Level

Open the hood and locate the brake fluid reservoir.
Inspect the fluid level; if low, top it off with the recommended brake fluid type (DOT 3 or DOT 4 for most Honda Civics).
Check for leaks if fluid was low.

3. Inspect Brake Lines and Calipers

Visually inspect all brake lines for cracks, corrosion, or wet spots indicating leaks.
Check the brake calipers for fluid seepage or damage.
Replace any damaged lines or calipers as necessary.

4. Replace Worn Brake Pads

Lift the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads; if worn below the manufacturer’s specifications, remove and replace them.
Ensure to replace both pads on the axle for even wear.

5. Test Brake Booster

With the vehicle off, press the brake pedal several times to deplete vacuum.
Start the engine; the pedal should drop slightly indicating the brake booster is functioning correctly.
If not, consider replacing the brake booster.
