my Skoda Octavia's brakes feel spongy what could be the issue

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and securely supported with jack stands.
• Wear safety gloves and goggles.

2. Check and Refill Brake Fluid

• Step 1: Remove the cap from the brake fluid reservoir.
• Step 2: Inspect the fluid condition; if it appears contaminated or low, proceed to refill or replace.
• Step 3: Add the appropriate type of brake fluid (DOT 4 recommended for most Skoda Octavia models) until it reaches the recommended level.
• Tools Required: Brake fluid, funnel.

3. Inspect and Bleed Brake Lines

• Step 1: Locate the brake bleeder valves on each brake caliper.
• Step 2: Attach a clear hose to the bleeder valve and place the other end in a container.
• Step 3: Have an assistant pump the brake pedal several times and hold it down.
• Step 4: Open the bleeder valve to release air and fluid; close the valve before the pedal is released.
• Step 5: Repeat until no air bubbles are present in the fluid.
• Tools Required: Brake bleeder kit, wrench for bleeder valves.

4. Inspect and Replace Brake Components

• Step 1: Remove the wheel to access the brake assembly.
• Step 2: Inspect brake pads for wear; if they are worn below the manufacturer's specification, replace them.
• Step 3: Check rotors for grooves or warping; replace if necessary.
• Step 4: Reassemble the brake components, ensuring all bolts are torqued to manufacturer specifications.
• Tools Required: Socket set, torque wrench, brake pads, rotors.
