ON-VEHICLE SERVICE
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.
