(c) Remove the 2 nuts and remove the brake master cylinder sub-assembly.
(d) Remove the O-ring from the brake master cylinder sub-assembly.
NOTICE:
-
The master cylinder requires careful handling. Do not allow the master cylinder to receive any impact, such as from being dropped. Do not
reuse a master cylinder that has been dropped.
-
Do not strike or pinch the master cylinder piston, and do not cause any damage to the master cylinder piston by any other means.
-
Make sure to release the vacuum from the brake booster before removing the master cylinder from the brake booster.
-
When installing the brake master cylinder sub-assembly onto the brake booster, or when removing the brake master cylinder sub-assembly
from the brake booster, make sure that the brake master cylinder sub-assembly is kept horizontal or its tip faces downward (the piston faces
upward) to prevent the master cylinder piston from falling off.
-
Do not allow any foreign objects to contaminate the master cylinder piston. If a foreign object gets on the piston, remove it by using a
piece of cloth and then apply an even layer of lithium soap based glycol grease around the circumference (sliding part) of the piston.
-
Do not use any other type of grease or fluid.
