E. Brake System Leak Check
Pull for a good firm hand brake and lock parking brake mechanism. Allow system to stand for
approximately 10 minutes; then by gripping parking brake handle, it should not be able to be pulled
aft further than original set. Should handle be able to be pulled towards panel and feel spongy, a
leak is present at some point in system. This leak may appear at any one of the connections
throughout system or internally in master brake cylinder or wheel brake assemblies.

bleeders and extend into container partially filled with hydraulic fluid, MIL-H-5606A. Ends

one-half to two turns.
(b) Fill brake reservoir on firewall with hydraulic fluid, MIL-H-5606A.

cotter pin.
