Description
Creating a brake with power and with the right feel, that was the challenge. Hayes did this by creating a whole new system. The Hayes Dominion A4 brake is factory set for the shortest possible backstop and a clean point of contact. The Dominion A4 brake caliper uses four pistons in the stiffest possible design. It features a cold forged caliper and KingPin pad retaining screw that increases stiffness. With a motorsport-inspired two-port bleed system, DOT 5.1 fluid and Kevlar hose, the hydraulic system is designed for peak performance in all temperatures and for easy and efficient maintenance.
The + products:
- High performance 4 piston hydraulic disc brake for use on trail, enduro, downhill and E-MTB bikes
- Hayes Peacemaker compatible
- CrossHair Alignment: alignment tool to perfectly adjust the brake caliper
- Ball bearing brake lever for better hand feel
- LoFi Technology: ?LoFi? stands for ?Low Input Force and High Fidelity Output Force? and results in a very high braking force due to low manual effort.
- King Pin Technology: The pad safety bolt also acts as a third screw to stiffen the caliper.
- 2-Stroke Dual Port Bleed System: two independent bleed ports on the caliper for absolutely safe bleeding
