PROBLEM
POSSIBLE CAUSE
PROCEDURE OR ACTION
The parking brake does not
release.
The hydraulic pressure is too low.
Check for low fluid level, air in sys-
tem, restricted lines, fluid leaks,
damaged seals or seals installed
backward.
The piston is cocked in the bore.
Replace piston if large end diameter
is less than 101.47 mm (3.995 in.) or
the small end is less than 63.37 mm
(2.495 in.).
Replace housing if the
large end of bore exceeds 101.68 mm
(4.003 in.) or the small end of the
bore exceeds 63.63 mm (2.505 in.).
