Parking Brake Problem

[KyleSeal]

I recently installed a 3/5 drop on my '70 and during the rear drop I went ahead and replaced my rear brakes, about 95% of the hardware was replaced with new original replacement parts.

Before drop, the parking brake worked great, held the truck in place relatively well, but now it doesn't really hold the truck at all. Parking brake all the way to the floor and just about nothing. There is drag in the rear brakes, the wheels can still turn with a good push (on jacks) but have drag, like I'd imagine they should.

Anyone else had this problem? Is it with the new drop that the cable cant get enough tension?

Very possible the drop caused a distance change creating more cable slack. Have you tried tightening the adjustment where the single pedal cable meets the duals?
