3. Check diaphragm piston travel by running
engine and moving transmission selector lever
from drive to neutral. The manual release lever
should move up and down as vacuum is applied and
released. If no movement is observed, or if move-
ment is slow, (more than one or two seconds to
complete the full stroke) diaphragm is leaking.
Replace diaphragm as described in Note 14.
4. Check brake release with vacuum applied.
If diaphragm piston completes full stroke but does
not release brake, a malfunction of the pedal

brake assembly as described in Note 13.

off. Parking brake should remain engaged regard-
less of transmission selector lever position. If
not, replace parking brake assembly.
