What can fail
Cracks can form in the mounting surface of Aeroquip Maxi II 30/36 spring parking brake chambers, causing the chamber housing to fracture near the studs. If the push rod clevis separates from the slack adjuster and air hose fittings break, the chamber could detach from the vehicle.
What the fix does
Brake chambers will be replaced with a redesigned chamber model.
