No, this mineral oil is not compatible with DOT fluid brake systems such as SRAM or Avid, since the two fluid types use different seal materials and are not interchangeable. Using mineral oil in a DOT system, or DOT fluid in a mineral-oil system, can damage internal seals, so always confirm your brake's fluid type before topping up or bleeding.

Shimano hydraulic disc brakes use mineral oil, and this is usually noted on the brake lever body or in the owner's manual that came with your bike. If your bike has SRAM, Avid or certain other brands' hydraulic brakes, check the manual specifically, since those commonly use DOT fluid instead.

Using a bleed kit such as our Shimano Brake Bleed Kit, you fill a syringe with this mineral oil and push it through the caliper bleed port while drawing fluid out at the lever, which flushes out any trapped air bubbles from the system. Once the fluid runs clear and bubble-free at both ends, close off the ports and check that your lever feels firm again.

Most riders bleed their brakes once or twice a year, or sooner if the lever starts to feel spongy or the bite point creeps closer to the bar. Heat from long descents, common on hilly Indian roads, can introduce tiny air bubbles into the fluid over time, so keeping a bottle of this oil on hand for periodic bleeds is a good habit.

A 60ml bottle is generally sufficient for bleeding one or two brakes at home, since a bleed uses a small amount of fresh fluid to flush the system rather than filling it from empty. Keeping a spare bottle around means you are ready whenever brake feel starts to soften.
