• Refer to "Wheels and Tires" in Section 3E.
• Pump the brake pedal several times to make
sure that the pedal is firm. Check the brake fluid
level in the reservoir after pumping the brakes.
SERVICING THE ROTOR
In the manufacturing of the brake rotor, all the
tolerances regarding surface finish,
parallelism and
lateral
runout are held very closely. The maintenance
of these tolerances provide the surface necessary to
assure smooth brake operation.
LATERAL RUNOUT
Lateral runout is the movement of the rotor from side
to side as it rotates on the spindle. This could also be
referred
to as "rotor wobble".
This movement causes the piston to be knocked back
into its bore. This results in
additional pedal travel and
a vibration during braking.

W CAUTION:
~ Replace all components included in repair kits used to service this system. Lubricate rubber parts with
clean, fresh brake fluid to ease assembly. Do not use shop air with in-line lubricators on brake parts,
as
damage to rubber components may result. If any hydraulic component is removed or brake line
disconnected,
it may be necessary to bleed part or all of the brake system.
NOTE:
The use of rubber hoses or parts other than those furnished specifically for the Anti lock Brake System may
lead to functional problems requiring major overhaul.
