This method worked well for me to engage rear adjusters. Give it a try.

Depress emergency brake pedal until you feel resistance. Back up truck and get on the brakes with strong/firm braking action. Release E-brake and drive forward a few feet. Repeat the process until you have max benefit.

As I see it, the master cylinder piston stops due to front brake pressure before the rear cylinders have enough fluid pressure to properly engage rear shoes. Results, no rear self-adjusting action. Depressing the E-brake corrects this and provides the needed fluid pressure action to rear cylinders/drums.

Good info...thanks. And I thought they flat didn't work..

Thanks I'll have to try that.

I'll have to try that on my Mom's truck... Neat Idea!

would applying the parking brake until the truck stops while going in reverse acomplish the same thing?

It's supposed too, but never has for me.

Sorry guys but the emergency pedal does nothing for the fluid movement of the brake system, The only correct way to adjust the rears is to jack her up and get after it. Goodluck,,Rick

Yep.. cable operated..

I prefer to hear the sound of the linings as they scuff the drum when I adjust them occasionally - that way I can tell if the shoes are wearing out-of-round or if drums are starting to have issues. Kinda hard to hear the rear brakes inside the cab with the motor rattling.

Not that this idea doesn't work, I just prefer to tinker on her occasionally and that is one excuse I have to boot the Porsche out of the shop and get the CTD inside for a couple of hours. Makes her feel a little more appreciated, and we all now how women like to be treated special

When I changed my wheel cylinders I just did a ballpark adjustment then went down the driveway pretty fast in reverse locking up all tires. After doing this a few times the rear brakes were grabbing nicely. Actually though I'm starting to wonder if they are doing to good, I just moved my truck in the driveway and the rears are pretty grabby (I could have the rears about lock up before the fronts will even start to kick in). I'm thinking it is from setting a little bit in high humidity? It doesn't seem to do it after being on the road.

Only sure way to adjust is by doing it manually, to ensure both drums are braking equally. Adjusters are notorious for so-so equalization(from side to side), and not getting tight enough braking action. I usually check and adjust every time I rotate tires, usually every 10,000miles.

I do it manually when my parking brake becomes worthless. I have never seen a well functioning set of self adjusters.
