Before I reply, please know that I have used my E-brake for parking only about 5 times in over 70K miles of Viper ownership. This problem is likely only encountered by 'habitual' E-brake users.
I DO use it to adjust the rear brakes, however !?!?!
Each time you apply the E-brake, the cable automatically adjusts the rear brake pistons/pads a teensy-tinsy bit closer to the rotors, down to a pre-set limit. I have actully convinced myself that increased rear brake bias has been achieved (especially on worn pads) just by setting the COLD brake 8-10 times before track events. (Could be a placebo ...but I THINK it works! Don't tell the competition.}
A clock-spring like automatic take-up adjuster is inside the console. I dont think a take-up adjustment can be made inside the console itself, but I don't have a service manual open. An allen wrench (7/32) can RELEASE that spring for removal and replacement. That spring can also unwind! I "assume" it can be tightened and certainly replaced.
