Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and set the parking brake.
Wear safety goggles and gloves.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the hood and locate the brake fluid reservoir.
2. Remove the cap and check the fluid level; add high-quality brake fluid (DOT 3 or DOT 4) if low.
3. If the fluid appears dark or contaminated, proceed to replace it.

3. Bleed the Brake System

Sub-steps:
1. Start with the wheel furthest from the master cylinder (usually the right rear).
2. Attach a clear hose to the bleeder valve on the brake caliper and place the other end in a container.
3. Have an assistant pump the brake pedal several times, then hold it down.
4. Open the bleeder valve to release air and old fluid, then close it before the pedal is released.
5. Repeat this process until clear, bubble-free fluid flows out.
6. Move to the next wheel in the order: right rear, left rear, right front, left front.

4. Inspect Brake Components

Sub-steps:
1. Remove the wheel to access the brake calipers and pads.
2. Check pads for wear; replace if worn below the manufacturer’s specifications (usually 3mm).
3. Inspect rotors for scoring or warping; replace if necessary.

5. Check and Replace Master Cylinder (if needed)

Sub-steps:
1. If sponginess persists after bleeding, check the master cylinder for leaks or internal failure.
2. Disconnect the brake lines and remove the master cylinder from the brake booster.
3. Install the new master cylinder and bleed the brake system again to remove any trapped air.
