This group was founded in September 2000 for the purpose of providing information and technical support to the burgeoning ranks of Hayes disc brake users. A THUG member must be loyal to his fellow THUGs. A THUG member must continually contribute to the bicycling community in some way. Membership is open to anyone who can follow the above rules.
Hayes have one of the most impressive and informative websites around.
It includes online manuals, adaptors, FAQ's and some pretty swanky graphics too. Click on the tech logo above to be teleported now. Using mineral oil intended for shimano or magura brakes will ruin all the plastic and rubber parts inside your brakes. DOT 5.1 fuild also works, it has the same chemistry as DOT 4 but a higher boiling point. Remove the pads from the calipers before any attempt to bleed the brakes.
