12-24 BRAKES
Brake Fluid

                        WARNING
 When working with the disc brake, observe the pre-
 cautions listed below.
 • Never reuse old brake fluid.
 • Do not use fluid from a container that has been left
   unsealed or that has been open for a long time.
 • Do not mix two types and brands of fluid for use
   in the brake. This lowers the brake fluid boiling
   point and could cause the brake to be ineffective.
   It may also cause the rubber brake parts to dete-
   riorate.
 • Don’t leave the reservoir cap off for any length of
   time to avoid moisture contamination of the fluid.
 • Don’t change the fluid in the rain or when a strong
   wind is blowing.
 • Except for the disc pads and disc, use only disc
   brake fluid, isopropyl alcohol, or ethyl alcohol for
   cleaning of the brake parts. Do not use any other
   fluid for cleaning these parts. Gasoline, engine
   oil, or any other petroleum distillate will cause de-
   terioration of the rubber parts. Oil spilled on any
   part will be difficult to wash off completely and will
   eventually deteriorate the rubber used in the disc
   brake.
 • When handling the disc pads or disc, be careful
   that no disc brake fluid or any oil gets on them.
   Clean off any fluid or oil that inadvertently gets on
   the pads or disc with a high flash-point solvent.
   Do not use one which will leave an oily residue.
   Replace the pads with new ones if they cannot be
   cleaned satisfactorily.
 • Brake fluid quickly ruins painted surfaces; any
   spilled fluid should be completely wiped up im-
   mediately.
 • If any of the brake line fittings or the bleed valve is
   opened at any time, the AIR MUST BE BLED FROM
   THE BRAKE LINE.
