how to fix spongy brake pedal on Honda Accord 8th Generation (2008-2012)?

Solution

1. Preparation

• Gather all necessary tools and parts.
• Park the vehicle on a level surface and engage the parking brake.
• Wear safety gloves and goggles for protection.

2. Inspect and Replace Brake Fluid

1. Locate Master Cylinder: Open the hood and find the brake master cylinder.
2. Check Fluid Level: If the fluid is low, top it up with the recommended brake fluid (DOT 3 or DOT 4, depending on vehicle specifications).
3. Replace Fluid: If fluid is contaminated:
   • Use a turkey baster to remove old fluid from the reservoir.
   • Fill with fresh brake fluid.

3. Bleed the Brake System

1. Connect Bleeder Kit: Attach a brake bleeder kit or a clear plastic hose to the bleeder valve on the farthest brake caliper from the master cylinder.
2. Open Bleeder Valve: Have an assistant press the brake pedal while you open the valve to release air and fluid. Close the valve before the pedal is released.
3. Repeat Process: Move to the next caliper (in order: rear passenger, rear driver, front passenger, front driver) and repeat until no air bubbles are visible in the fluid.
4. Check Master Cylinder: Keep the master cylinder filled with fluid during the bleeding process to avoid introducing more air.

4. Inspect Components

1. Brake Pads and Rotors: Remove the wheel and inspect the brake pads and rotors for wear. Replace if necessary.
   • Use a torque wrench to tighten the wheel lug nuts to the manufacturer’s specifications after reinstallation.
