E-brake adjustment, rear drums
I recently replaced the front discs, rotors, and calipers, and bled the fronts.
When the rear tires are up, wheels are spun, and brakes applied, the wheels stop.
The drums have 7mm walls, and the riveted shoes have 4mm friction material.
The e-brake handle comes WAY up. Both sides have the arm moving, but clearly not enough to engage the brakes.
Do I need to bleed the drums? Do I need to adjust them (either drive and slam in reverse or use a screwdriver?
How else would I adjust the parking brake when we know the cables are intact?
Thanks!

Re: E-brake adjustment, rear drums
Take off the drums, and adjust the shoes up to the point that it's HARD to get the drums back on, but not impossible. Drive the car around a few miles. Check the parking brake (there's no "e brake") and see how many clicks it takes to engage. Should be around 12, preferably more like 10, before the handle is maxed out. Get up under it and adjust the nut behind the plate where the front cable meets the 2 rear cables to make it like that, if necessary. Most likely, once you get the shoes adjusted properly, the parking brake will be OK. Then, EVERY SINGLE TIME you back the car up, make a point of backing it up kinda quick and using the brakes HARD. The act of using the brakes in reverse adjusts them, so do that, to keep them in adjustment. You may even hear them working when you do what I describe.
