Scotty Kilmer, mechanic for the last 49 years, shows how you can use a simple tool to find out if your brake fluid needs changing or not. Why trust someone else to test it when you can do it yourself with a low cost tool?
yep, years later it's still working. they are rather simple design, so if one originally works, it can go pretty much forever as there are no real wearing out parts. But if they dont work from the get go, that's another story.
Hey Scotty, are you still using this same tool? I bought one on-line and it didn't work. It was so cheap that I didn't try to return it, but I am curious if you have upgraded or changed suppliers to a more reliable brand, please let us know.
