12-10 BRAKES Brake Fluid W ARNIN G When working with the disc brake, observe the pre- cautions listed below. 1. Never reuse old brake fluid. 2. Do not use fluid from a container that has been left unsealed or that has been open for a long time. 3. Do not mix two types and brands of fluid f or use in the brake.
BRAKES 12-1 1 Brake Fluid Brake Line B leeding The brake flui d has a very low compres sion coefficient so that almost all the movement of the brake lever or pedal is transmitted directly to the caliper for braking action. Air , however , is easily compressed.
12-12 BRAKES Brake Fluid • Bleed the brake line and caliper as follows: ○ Repeat this oper ation until no more air can be seen com- ing out into the clear plastic hose. 1. Pump the brake lever until it beco m es hard, and apply the brake and hold it [ A].
BRAKES 12-13 Caliper Caliper Remov al Front Bra ke • Loosen the brake pad pin [A] before the caliper [B] re- moval if the caliper is to be disassembled.
12-14 BRAKES Caliper Caliper Installation • Install the br ake pad if it was r emoved (see Brake Pad Install ation). Front Brake • Install the caliper and tighten the bolts.
BRAKES 12-15 Caliper Fluid Seal Damage Inspection The fluid seal(s) [A] around the piston maintains the proper pad/disc clearance. If this seal is not in good condi- tion, pad wear will increase, and constant pad drag on the disc will raise brake and brake fluid temperature.
12-16 BRAKES Caliper Caliper Piston and Cylinder Damage I nspection • V isually inspect t he piston(s) [A] and cylinder surfaces. Replace the ca liper if the cyli nder and piston are badly scores or rust y .
BRAKES 12-17 Brake Pad Brake Pad Removal Front Bra ke • Remove the pad pin [A]. • Rem ove the pis ton s ide p ad [B]. • Push the caliper holder toward the pi ston, and then re- move another pad [C]. Rear Brake • Remove: Pad Pin Plug [A] • Remove the pad pin [A].
12-18 BRAKES Brake Pad • T ighten the brake pad pin. T orque - Brake Pa d Pin: 17 N·m (1.7 kgf·m, 13 ft·lb) Rear Brake Pad Pin Plug: 2.4 N·m (0.2 4 kgf·m, 21 in·lb) • Check the brake for good braking power , no brake drag, and no fluid leakage.
BRAKES 12-19 Master Cylinder NOTICE Brake fluid quickly ruins painted or plastic sur- faces; any spilled fluid should be completely washed up imm ediately . Front Mas ter Cylinder Removal • Remove the banjo bolt [A] to disconnect the brake hose upper end [B] from the master cylinder [C].
12-20 BRAKES Master Cylinder • The master cylinder clamp m ust be inst alled w ith the ar- row mark [A] upward. • T ighten the upper clamp bolt [B] first, and then the lower clamp bolt [C]. ○ There will be a gap at the lower mating surface of the clamp after tightening.
BRAKES 12-21 Master Cylinder • Replace the cotter pin w ith a new one. • Install the joint pin, washer and new cotter pin. • Bend the ends [A] of the cotter pin. • Check the brake pedal position (see Brake Lever and Pedal Adjustment in the Periodic Mai ntenance chapter).
12-22 BRAKES Master Cylinder Master Cylinder Inspection (V isual Inspection) • Disassemble the front and rear master cylinders. • Check t hat ther e are n o scratches, rust or pitting on the inner wall of each master cylinder [A] and on the outside of each piston [B].
BRAKES 12-23 Brake Disc Brake D isc Remov al • Remove the wheels (see Front/Rear Wheel Rem oval in the Wheels/T ires chapter). • Remove the mounting bolts, and take off the di sc. Brake Disc Installation • Install the brake disc on the wheel so that the marked side [A] f aces out.

Special T ools - G rip: 570 01-15 91 Rotor Hold er: 57001-17 30 T orque - Flywheel Nut: 78.5 N·m (8.00 kgf·m, 57.9 ft·lb) • Install the magneto cover (see Magneto Cover Inst alla- tion).
ELECTRICAL SYSTEM 16-15 Flywheel Magneto Flywheel Inspection There are three types of m agneto problems: shor t, open (lead burned out), or loss in flywheel magnetism. A short or open in one of the coil leads wil l result in either a low output, or no output at all.
16-16 ELECTRICAL SYSTEM Flywheel Magneto If there is more resist ance than shown in the table, or no hand test er reading (infini t y), the stator has an open lead and must be r eplaced. Much less than this resi stance means the stator is shorted, and must be replaced.
