Solution

1. Preparation

Gather tools and parts needed for the brake fluid change.
Tools Required: Brake fluid tester, funnel, clean rags, socket set, and a container for old fluid.
Safety Warnings: Always wear safety goggles and gloves when handling brake fluid, as it can damage paint and is corrosive.

2. Remove Old Brake Fluid

Locate the brake fluid reservoir under the hood.
Use a turkey baster or similar tool to siphon out the old brake fluid from the reservoir.
Dispose of the old brake fluid according to local regulations.

3. Inspect and Clean

Check the brake fluid reservoir cap and area for dirt or debris; clean if necessary.
Inspect brake lines and calipers visually for any signs of wear or leaks.

4. Add New Brake Fluid

Open a new bottle of brake fluid that meets the specifications for your Skoda Octavia (typically DOT 4).
Using a funnel, carefully pour fresh brake fluid into the reservoir up to the MAX line.
Ensure the reservoir cap is securely fastened after filling.

5. Bleed the Brakes (if necessary)

If air was introduced into the brake lines, bleed the brakes using the following steps:
- Starting with the wheel farthest from the master cylinder, loosen the bleeder screw on the brake caliper.
- Have an assistant press the brake pedal while you open the bleeder screw to release air and fluid.
- Close the screw before your assistant releases the brake pedal. Repeat until no air bubbles are present.
- Move to the next wheel and repeat the process until all brakes are bled.
