my Skoda Octavia's brakes feel spongy what should I do

Solution

1. Preparation

• Tools Required: Brake fluid, container for old fluid, wrench set, vacuum bleeder (if available).
• Safely lift the vehicle using a jack and secure with jack stands. Ensure the engine is off and the vehicle is in gear or park.

2. Inspect and Replace Brake Fluid

• Remove the brake fluid reservoir cap and inspect the fluid level.
• If the fluid is low, top it off with the appropriate brake fluid type (DOT 4 or as specified in the owner's manual).
• If the fluid appears dirty or contaminated, proceed to replace it.

3. Bleed the Brake System

• Connect a vacuum bleeder to the brake bleeder valve on the farthest brake caliper (usually the rear passenger side).
• Open the bleeder valve slightly and allow the old fluid to flow into the container until clear fluid comes out.
• Close the bleeder valve and repeat the process on the remaining calipers in the following order: rear passenger, rear driver, front passenger, front driver.
• Ensure to keep the brake fluid reservoir topped up during this process to prevent air from entering the system.

4. Inspect and Replace Brake Components (if necessary)

• If sponginess persists, inspect the brake pads and rotors for wear. Replace them if they are below the manufacturer's specifications.
• Check the master cylinder for leaks and replace if necessary.
