Hello guys, I’ve probably made bullshit with my brake system. The ABS block and the brakes have to be ventilated. I’ve heard that GM Tech 2 should be used for many years. I’ve seen it before. it’s balanced with gold. Now I’d have some questions about it. What do you need to do about GM Tech 2? I’ve also heard about a clone. Can it be the same as the original device? Are there any other devices? I got an offer. 99 Euro. For a 2-3 times application too expensive. Thank you in advance for your ideas.
