Solution

1. Preparation

Gather the following tools: jack and jack stands, socket set, brake line wrench, brake fluid, funnel, and a clean cloth.
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Check and Refill Brake Fluid

Sub-step 1: Open the brake fluid reservoir cap and check the fluid level.
Sub-step 2: If low, add the appropriate brake fluid (DOT 4 recommended for Skoda).
Sub-step 3: Re-secure the reservoir cap after refilling.

3. Bleed the Brake System

Sub-step 1: Start at the wheel farthest from the master cylinder (usually the right rear).
Sub-step 2: Attach a clear hose to the bleeder valve on the brake caliper and submerge the other end in a container filled with brake fluid.
Sub-step 3: Have an assistant press the brake pedal several times, then hold it down.
Sub-step 4: Open the bleeder valve to release air and fluid, then close it before your assistant releases the pedal.
Sub-step 5: Repeat this process until no air bubbles are visible in the fluid.
Sub-step 6: Move to the next wheel, following the same procedure (right front, left front, left rear).

4. Inspect and Replace Components

Sub-step 1: If the fluid was leaking, inspect brake lines for damage and replace if necessary.
Sub-step 2: Check the brake master cylinder for leaks; if leaking, replace it.
Sub-step 3: Inspect the brake pads and rotors; replace any worn components as needed.

5. Final Assembly

Sub-step 1: Ensure all bleeder valves are tightened.
Sub-step 2: Recheck the brake fluid level and top off if necessary.
Sub-step 3: Re-secure all components and replace any covers removed during the process.
