I have a 2006 1500 LT Ext Cab 4x4 with rear drum brakes. I replaced the shoes yesterday and all is well except the parking brake lever seems to have much more travel than it did before. Rear brakes are adjusted fine, parking brake seems to work fine, pedal just goes almost all the way to the floor which is didnt do before. I jacked up the rear of the truck and engaged the parking brake to make sure the cable was connected at both rear wheels and it they were both engaged. I would like to have the same resistance on the parking brake pedal as I did before so I know if I am on a really steep incline or something I am fully enagaged. I checked my manual and it said the parking brake is self adjusting and a search on here seemed limited to disc brakes in the rear. Any ideas?
