Bike maintenance essential that helps keep hydraulic brakes performing predictably, introduced as SHIMANO Disc Brake Mineral Oil. Confidence on steep descents comes from brake feel that remains consistent after bleeding and seal care. Is one 100 ml bottle sufficient for a full front and rear bleed on most setups?
⚡ At a Glance
- • Brake Performance: Genuine mineral oil formulation maintains steady hydraulic response and compatibility with Shimano systems
- • Best for: Cyclists using Shimano hydraulic disc brakes who want reliable maintenance fluids
- • Not ideal for: Riders who require DOT-spec brake fluids for non-mineral hydraulic systems
Genuine SHIMANO mineral oil supplied in a 100 ml bottle, intended for hydraulic disc brake maintenance. Useful for bleeding and cleaning around caliper seals to restore consistent braking.
Consistent braking feel - thanks to mineral oil formulation
Mineral oil is chemically compatible with Shimano seal materials and hydraulic components, avoiding the corrosive effects associated with some other fluids. The stable fluid composition supports consistent viscosity under normal riding temperatures.
Predictable lever feel and modulation after a proper bleed, so braking remains reliable during long descents and repeated stops.
Clears sticky calipers - with cleaning action around seals
Flushing mineral oil through caliper seals helps remove trapped grime and old fluid residues, allowing pistons and seals to move freely again. User reports note effective cleaning around caliper seals when performing routine maintenance.
Sticky or lagging calipers can return to smooth operation after a careful bleed and seal flush, improving pad alignment and brake response.
Enough volume for a complete service - with 100 ml bottle capacity
A single 100 ml container provides a measured quantity suitable for typical front and rear brake bleeds on many bikes, according to user experience. The bottle size also suits workshop or home maintenance without large storage needs.
One bottle commonly suffices to bleed both front and rear systems, reducing the need to buy multiple small containers for a single service.
