Excaliber Ernie Mr Mustang has it right with killing a battery in 8-10 hours. I don't think you want to see the cobra rolling down the street empty. You should not need to keep adjusting you parking brake unless you are pulling YOUR HANDLE too tight or hard. All you need is enough to hold the car in position. Leave the trans in gear too. If on a hill, back in and turn the right tire to hit the curb. Line lock will bleed off pressure over an hour or so. It gets low pressure and the car rolls. Other thing is if the rotors are hot, pads will get burnt and glaze. May effect the rear brakes over time with material bonded to the surface of the rotors.

It sounds like you are stretching out the cable or bented the arms on the parking brake levers. Either way too much muscle. Try this test, car on flat ground. Have the parking brake adjusted. Pull up on the lever until the car will not move with you pushing it. 1 more click on the hand brake arm. that's it.The other thing is how much material is left on the brake pads for parking??If less than 1/2, get new pads and retry.

Currie ent. sells a parking brake assembly that goes to the yoke of the differential with a motor cycle size caliper and brackets. I just don't think there is enough room to fit this inside the tunnel and clear the rearend frame.It might be modified to work with some engineering. Rick L.
