no most floor jacks use an ISO 32 hydraulic oil using brake fluid, tranny fluid, or motor oil will screw up the seals.
In fact, hydraulic fluid and hydraulic oil are terms that are at times used interchangeably. There are many applications of hydraulic oil, and one of them is hydraulic brake fluid. Hydraulic brake fluid is produced using water or refined mineral oils depending on the brand.
Under NO circumstances put brake fluid or engine/gearcase/olive/sunflower oils in with the mineral fluid. Vegetable oil and LHM are both examples of mineral oil. At a push, vegetable oil will work fine. I've used it in Magura HS33 brakes (also take mineral oil).
Shimano use mineral oil in all their brakes. The proper stuff is pretty thin, and specially formulated (so Shimano claim anyway) to have a quite high boiling point. Baby oil could be used in an emergency, but its higher viscosity could affect performance, and may have a lower boiling point than the proper stuff.
Alternatives for mineral brake fluid / oil (in a pinch)
- Fork cartridge oil (the lighter (more viscous) variant)
- Total / Castrol LHM Plus Fluid ( I believe it's power steering fluid)
Wrehch. Most PS fluids are nothing but a form of hydraulic fluid. It should work just fine. If you still don't feel safe using it, most auto parts stores sell hydraulic jack oil in quarts.
Yes. Both reverb oil and Shimano oil are mineral and similar viscosity. I wouldn't use reverb oil in Shimano brakes as it looks like it's made by Maxima and they do use seal swellers which I would test on Shimano seals before committing it to a bleed.
DOT fluid will knacker the seals on a mineral oil-based system, and the brakes will fail. It's true that many colours and types of mineral oil exist, but that doesn't neccesarily mean it's OK to put in your brakes.
It is perfectly safe to use it, just not to mix it with the old mineral oil. You must do 2 or 3 bleeds till you are sure that the system contains only chf 11s. After that it is totally ok to use it. Been using it since the second bleed of my zees, and the brake levers actually feel better.
The seals in the brake are likely to fail with you using DOT fluid, as they are designed to work with mineral oil. DOT fluid will cause premature wear/swelling of the seals in the lever and caliper, neither is a good place.
Q: Can I use any mineral oil in my Tektro disc brakes? No, Tektro disc brakes are designed to be used with only Tektro brand mineral oil. Tektro uses a special additive to increase the temperature range and red color for ease of identification.
Here's what Shimano have to say: "We actually see this as a major advantage of using Mineral Oil. We don't have to trust anyone else's testing standards for the fluid they make. Since every Shimano brake uses Shimano brake fluid, we have complete control over the process and can assure consistent performance."
No, mineral oil and DOT brake fluid are different and are NOT compatible.
There are two types of brake fluid used in hydraulic bicycle bike brakes today: DOT Fluid and; Mineral Oil.
As a lubricant, it reduces friction and protects component surfaces that undergo metal-to-metal contact that can result in wear. It also helps keep components cool by conducting heat away. Hydraulic fluid also protects metal surfaces from corrosion, provides a viscous seal, and resists water.
A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed.
When you have low brake fluid it can affect your brake pads. Brake pads are essential to your car's braking system, so having low brake fluid can cause brake pads to not work like they should.
The three main types of brake fluid now available are DOT3, DOT4 and DOT5. DOT3 and DOT4 are glycol-based fluids, and DOT5 is silicon-based. The main difference is that DOT3 and DOT4 absorb water, while DOT5 doesn't. One of the important characteristics of brake fluid is its boiling point.

Brake fluid is a type of hydraulic fluid used in hydraulic brake and hydraulic clutch applications in automobiles, motorcycles, light trucks, and some bicycles. It is used to transfer force into pressure, and to amplify braking force. It works because liquids are not appreciably compressible.
The main requirements for brake fluids are high operation temperatures, good low-temperature and viscosity-temperature properties, physical and chemical stability, protection of metals from corrosion, inactivity with respect to mechanical rubber articles, and lubricating effect [6].
Yes, DOT 3 brake fluid is compatible with DOT 4 brake fluid. However, DOT 4 offers a higher boiling point. It's not compatible with the other brake fluids and is used mostly in classic cars that remain in storage for long periods and need a brake fluid that doesn't absorb water.
Blending brake fluids is generally a bad idea! DOT 3: Usually formulated with a glycol-ether base. The minimum dry boiling point (pure brake fluid) is 401 F, and wet (measured with about 4 percent water mixed in the fluid) is 205 F. It's appropriate for regular vehicles used for typical purposes, like commuting.
DOT3 is the most common type of brake fluid used by daily drivers. You can expect to find that most cars and trucks use this type. Essentially it's for vehicles that don't use their braking system aggressively, ie don't turn the kinetic energy into heat that DOT 3 can't handle.
Examine the color of the brake fluid.Like we said above, fresh brake fluid should be almost clear with a hint of yellow coloring. If your brake fluid resembles oil, and is a dark brown or black color, then you need a brake fluid flush and replacement.
