Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Wear safety gloves and goggles.

2. Inspect and Top Off Brake Fluid

Locate the master cylinder reservoir under the hood.
Remove the cap and check the brake fluid level.
If low, top off with manufacturer-recommended brake fluid (DOT 3 or DOT 4).
Reinstall the cap securely.

3. Check for Brake Fluid Leaks

Visually inspect all brake lines, calipers, and wheel cylinders for signs of fluid leakage.
Look for wet spots or corrosion on components.
If leaks are found, replace the damaged lines or components.

4. Bleed the Brakes

Start with the wheel farthest from the master cylinder (usually the right rear).
Attach a clear tube to the bleeder valve and place the other end in a container.
Open the bleeder valve and pump the brake pedal until fluid runs clear of air bubbles.
Close the valve and repeat on the left rear, then both front wheels in order.
Keep checking the master cylinder fluid level and top off as necessary.

5. Replace Worn Components

If brake pads or rotors are worn, replace them.
Ensure that all calipers and mounting hardware are in good condition.
Follow torque specifications for caliper bolts (typically around 25-30 lb-ft for Honda vehicles).
