Brake Systems
ATTENTION!
Please remember that the stopped engine and the
disabled vacuum booster considerably increase the effort necessary
for pushing the brake pedal to stop the vehicle.
ATTENTION!
If one of the brake circuits is broken, the pedal
travel is increased and breaking efficiency is decreased. In this case do
not do short-time multiple pedal pushes, instead push the pedal until
the maximum breaking.
If the brake system does not work properly, it is forbidden to drive
the vehicle or to tow it with a tow-rope. In this case use two wheel
towing or tow truck service.
ATTENTION!
Brake fluid is poisonous. Keep it in a tightly closed
container. While working with it follow these rules:
-
avoid any mouth contact with the fluid;
-
do not let the fluid dry out on the skin; wash it off with soap and
warm water immediately;
-
flush the spilled fluid with water, ventilate the room;
