my Honda Civic 9th Generation (2012-2015) brakes feel soft, what should I check?

Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Wear safety glasses and gloves for protection.

2. Brake Fluid Inspection

• Open the hood and locate the master cylinder reservoir.
• Check the brake fluid level; it should be between the minimum and maximum marks.
• If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).

3. Brake Line Inspection

• Visually inspect the brake lines for any signs of leaks, corrosion, or damage.
• If a leak is detected, replace the damaged section of the brake line.
• Tighten any loose fittings to ensure proper sealing.

4. Brake Pad and Rotor Inspection

• Remove the wheel to access the brake components.
• Inspect brake pads for thickness; replace if they are worn down to the minimum thickness (usually 3mm).
• Check rotors for warping or scoring; machine or replace as necessary.

5. Brake Booster Testing

• With the engine off, pump the brake pedal several times to deplete any vacuum.
• Hold the pedal down and start the engine; the pedal should move slightly downward if the booster is functioning properly.
• If the pedal does not move or feels hard, the brake booster may need replacement.
