I filled my mountain bike brakes with baby oil for a year and here are the results

A little over a year ago we filled the rear hydraulic brake of my fat tire mountain bike with baby oil, instead of Shimano Brake oil. Now over a year later, we re going to tear apart the brakes and look at all the most vulnerable components under a microscope to see if they degraded or changed in any way. This video is just for entertainment, and I can t recommend that you fill your brakes with baby oil. With that said, this will always be the baby oil fat bike and it will always have baby oil in the brake
