[. . . ] 45-14573B Caliper Repair To repair the caliper, it must be removed from the bike and disassembled. [. . . ] Note: Take extra care to get the square seal grooves free of any hair, dirt, scratches, etc. Begin re-assembly of the caliper by lightly lubricating the new square seals with DOT 4 or DOT 3 brake fluid and installing the new seals in the caliper halves. With your fingers, rub DOT 4 or DOT 3 brake fluid all around the seal. Carefully push the square seal into its seal groove ­ making sure that the seal is worked into the groove all of the way around - and that it is pushed all of the way to the back of the seal groove. Put a coating of DOT 4 or DOT 3 brake fluid all around the piston as a lubricant, and carefully push the piston into the bore, past the seal, until it seats at the bottom of the bore. Note: The piston should push in easily, if it doesn't, take the piston out and again push the square seal all of the way to the back of the groove and then try again. Warning: The O-ring is a special material and should be purchased through the Hayes caliper service kit. These O-rings are a special material that will not react with DOT 4 or DOT 3 brake fluid.
