my hand brake on the 40 was working fine until recently.
since the bed is removed it makes it easier and an good time to investigate why they wouldn't release.
to get to the brakes on this timkin rear you must pull the axle, bearings and hubs off to get to the inner workings.
i removed the driver side cable first. it was stiff sliding but with some work and some silicone it glides easily in the sheath. i hooked it back up and tested for operation and works as designed. the passenger side spring came out in about five pieces but the cable is now free like the other one.
there isnt a part # in the GMC MPB for just the spring.
[editor assumption: GMC master parts book]
the whole cable is item # 4.7050 on page 70. it would be the same spring from a chevy.
everything else is good concerning the parking brake.
anyone know where i can get replacement springs or a dorman part # ?
