A way to check brake fluid level

I don't like to unscrew the brake mastet cylinder cap to check the brake fluid level. This is something that has to be done as offen as possible and it takes time, rises the risc of brake fluid contamination and harms the color. So I drilled the brake master cylinder cap, put a flexible line and an aluminium gasket. Then I took the line to a transparent fluid box mounted at the highest possible place. I can asure you that it works fine for more than a year. lIf you find the engine unknown it is because it is a 130Hp Steyr diesel.
