Best suited for use with Dot 5 Fluid
Frequently Asked Brake Fluid Questions:
DOT 4 and DOT 5 are NOT compatible, never mix them! If your master cylinder specifies using DOT 4, please continue using DOT 4. MID-USA brake calipers are designed to work with both fluid types.
DOT 4 and DOT 5 brake fluids are not compatible and react to each other resulting in a build-up of viscous materials that can interfere with metering orifices within the brake system.
DOT 5 is not compatible with ABS systems
*The general rule of thumb for brake caliper and master cylinder compatibility:
A smaller bore master cylinder will increase line pressure and therefore will generally increase braking power. However, keep in mind the volume of fluid your master cylinder is capable of moving needs to be enough to fully actuate the pistons in your brake caliper. If you have a small master cylinder trying to move multiple pistons in a large 4 piston caliper braking power could be compromised or lost. Brake compatibility, fitment, fluid choice, and bleeding are best left to professional motorcycle mechanics.
