User manual HAYES DISC BRAKES 45-17692ECFULL

[. . . ] You have purchased a Hayes Disc Brake system. This Manual is intended to provide the information necessary for normal maintenance and service of the Hayes Disc Brake system. Although the steps and procedures are relatively simple, they should not be attempted until you are thoroughly familiar with the entire set of procedures. Images have been provided to help you in the steps and procedures. TM SAFETY INFO Warning: As a serious rider you are well aware of the need to practice safety in all aspects of the sport. [. . . ] Warning: DOT 4 and DOT 3 brake fluid can be an irritant when it comes into contact with human tissue. For skin contact, brake fluid should be washed off in flowing water. For eye contact, the eye area should be irrigated with flowing water immediately and continuously for 15 minutes. If effects occur from inhaling brake fluid fumes, move to an area with fresh air. If brake fluid is ingested, induce vomiting and consult medical personnel. Used brake fluid should be disposed of in accordance with local laws. · Bleed Kit Assembly (Figure 4 C) 1. Screw the cap onto the end of the bottle. Push the short section of hose over the cap until it slides past the ridge on the cap 4. Push the long section of hose into the master cylinder bleed fitting. NOTE: There are three fittings with the kit. The black plastic fitting is to be used with the "El Camino". · Bleeding the System 1. Remove the brake pads so that any spilled fluid does not contaminate the pads. (See "Maintenance" instructions for pad removal) 3. Push the caliper pistons all the way into their bores using the box end of a 9mm end wrench. Caution: Don't push on the post in the center of the piston because that will bend the post. Take great care to remove all brake fluid because if the fluid comes into contact with the disc or brake pads, performance will forever be greatly reduced. 17 Clean the disc with isopropyl alcohol if it is contaminated with oil or brake fluid. Replace the caliper's rubber bleeder cap, the brake pads, and the wheel/disc assembly. Pump the brake lever to push the pads to the proper location. Master Cylinder Service (Figure 5) The right hand and left hand master cylinders are identical and will be rebuilt in the same manner. Rebuilding must be done with the master cylinder removed from the bike. NOTE: The Power Adjustment Dial is a non-serviceable item. [. . . ] Now repeat the procedure for the other pad. Piston(s) Pumped Out (Figure 3) If the brake lever is stroked without the disc between the pads (and this is possible when brake pads are being changed), the self-adjusting feature will allow the pads to push out. The caliper pistons will be pumped out of their bore. This would cause excessive drag on the disc when the wheel and disc are reinstalled, or even make it impossible to install the wheel and dsic.
