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 brakes until they fail. Maybe it's time we name this bike...

    There’s no economic rationale for doing this. Oil is a consumable, but it’s not like you’re using a high volume of it. A bottle of the Shimano stuff would probably last a few years.

    There are places that do detailed analyses of motor oils. They might be able to provide data for brake oil and OTL mineral oil. You can get a rough idea of viscosity by doing pour tests at various temperatures.

    When I rode trials, alot of us ran our magura hs33's on water, or water with a drop of anti freeze in winter. It made the breaks less spongy, more responsive, and lighter to pull. You'd get about a year out of the seals, but most trials riders broke a lever or something before then and had to get a new brake anyway! I'd be more than happy to use baby oil in a pinch :)

    I ran drug store mineral oil in my brakes and it worked great until the temps went down. Below freezing, the oil gets thick and it got to the point that applying brakes becomes difficult and the pads barely release at all.

    Dumb idea to use dot brake fluid (okay for downhill bike) bicycles are not going fast enough and brake surfaces are too small. Dot fluid needs to withstand instant, constant, and high temperatures from MOTORCYCLES braking. Shimano went the right route and baby oil seems to be just fine.

  40. gin ngo

    gin ngoПре 25 дана

    Like to see temperature gun reading on the different " brake " fluids after a typical down hill brake use. You can set up & bench bleed loose discs brakes a head of time & then install them & go on the same trail on the same bike. I've always believed when it came to " brake " fluids bike manufacturers were " shady " hence LBS don't usually inventory " brake " fluid for sale. Causing unnecessary expense to consumers for labor. Just use basic DOT car brake fluid. Cheaper, handles high heat temperatures on 2,000+ lbs cars & trucks & on a bike system 100% hydroscopic free.

    For "mineral" oil brake systems: Use engine oil or (better) automatic transmission fluid ATF (Yes, it is oil). Do NOT use brake fluid in those systems. Engine oil and ATF have additives which protect against corrosion, protects gaskets and O rings and more. They also have high boiling point. Synthetic oil is fine if you have it around, but it is an overkill. Baby oil does not have those additives and I doubt if Shimano's oil have them either. BTW: Some heavy equipment use ATF in their hydraulic system. If the manufacturer specifies brake fluid (DOT 4 usually), which is NOT oil, DO NOT use any oil. If you are considering a new brake system, go for "mineral". Brake fluid (mostly DOT4) is hygroscopic and will cause corrosion over time. It also dissolves some paints, so you don't want it spilled on your precious bike.

    Well here we are 9/24/2020 and I've found myself in the "theoretical Apollo 13 situation where you'll die in space without a brake oil substitute." Apparently because of Covid, can't find Shimano Brake fluid at any local shop and the big online retailers like Jenson. So bought some drug store generic 100% mineral oil to bleed, now that I know it's fine for seals (as I suspected) not going to worry about it. Great video.

    I can oneup your baby oil. I once filled up with suntan oil after carrying my bike to the Summit of Helvellyn then realising I had lost most of my brake fluid due to a cracked reservoir. I literally shouted out to a huge group of walkers having lunch at the top 'has anybody got any suntan lotion or I'm going to die!' A nice lady asked if I was serious and I explained about the lost brake fluid. We had already considered water, energy gel and each bodily fluid in turn and I mean every one. The suntan lotion was creamy with the consistency of head and shoulders shampoo. It worked even though I had to pump the lever a lot probably because of air in the system rather than the lotion not working. When I got home I flushed it through several times until there was no more suntan lotion coming through and it was fine. Next time I may try slightly salted butter...
