Alright, so maybe you already made the mistake. Don’t panic! You’re not the first person to confuse the two. First, drain the brake fluid completely. Most jacks have a small drain plug or a screw at the bottom. Catch the fluid in a container and dispose of it properly (brake fluid is toxic, so no pouring it in the garden).
How to Bleed Your Brakes for Optimal Performance
Next, flush the system with a little fresh hydraulic oil. Pour a small amount in, work the jack up and down a few times (without a load), then drain that out too. This gets rid of the leftover brake fluid residue. Finally, fill it with the correct oil, and you’re golden. Your jack will forgive you—eventually.
Let’s Not Make This a Habit
Look, I’m not here to judge your life choices. If you want to experiment with brake fluid in a jack, you do you. But I’ve seen the aftermath: a sticky mess, a broken jack, and a very sad DIYer. The auto parts store is right there, and the right fluid is cheap. Save your sanity and your safety gear for something fun, like trying to assemble IKEA furniture without losing a screw.
