Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is on a level surface and activate the parking brake.
Wear safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Open the master cylinder reservoir cap.
Inspect the brake fluid level; if low, add the recommended brake fluid (DOT 3 or DOT 4 for Honda).
Replace the cap securely.

3. Bleed the Brakes

Tools Required: Brake bleeder kit, wrench, clear tubing
Begin with the wheel furthest from the master cylinder (usually the right rear wheel).
1. Attach the clear tubing to the bleeder screw on the brake caliper.
2. Have an assistant press the brake pedal several times and hold it down.
3. Open the bleeder screw to release air and fluid, then close it before the pedal is released.
4. Repeat until no air bubbles appear in the tubing.
5. Tighten the bleeder screw and repeat for the left rear, right front, and finally the left front.

4. Inspect Brake Components

Tools Required: Socket set, torque wrench
Remove the wheel and inspect brake pads and rotors for wear.
Replace any worn brake pads or damaged rotors according to manufacturer specifications.
Ensure caliper mounting bolts are torqued to the manufacturer’s specifications.

5. Check Brake Booster

Tools Required: None
If the pedal is still soft after bleeding, check the brake booster.
Inspect the vacuum hose for leaks and ensure the booster itself is functioning correctly.
