Parking Brake Adjustment
I was parking on a slight incline on a buddy's driveway the other day and when i engaged the parking brake after putting the truck in neutral, the truck started to roll back. on a flat surface it seems to be fine so im thinking since the parking brake lever pushes the brake shoes in the back, would adjusting the brake shoes help apply the parking brake better if the shoes were to be slightly out of adjustment? and also, does anyone know is my rear drums and shoes are 2.5 inch or a 3 inch? its a 1993 F-250 7.5L 4x4 with the ZF5 transmission. thanks

When were the park brake cables last replaced? Good chance one of them is seized and you're actually only engaging 1 side when using the park brake. The shoes many not be adjusted the same either, I would think that truck would have 3" shoes with that powertrain.. it's probably a HD model.

Cables could be seizer, brakes out of adjustment, or the equalizer on the brake cables could need adjusting because the brake shoes have worn some.
I adjusted my cable, located under drivers door, a few years ago and have had excellent parking brakes since. I always hold the foot brake down with engine running to make sure I get full braking, especially when parking on a hill. I find it's not unusual to have to push another click into the pedal after the truck shifts rearward a little.

The adjustment is actually in front of the drivers side spring hanger, under the bed. I said under the door area, but was wrong. I either remembered wrong, (no, not me, lol), or that's where my Dodge is. I've adjusted both.

Half ton use the 2.5" shoes with an 8.8. 10.25" SRW get the 3", DRW 3.5"
I would pull the drums and eyeball around. Auto adjusters run about $10/side in my area. Cables are shockingly inexpensive if needed.

I had to change both parking brake cables on my '87. They got to hanging up when the parking brake was applied. The new ones are plastic coated sheaths instead of metal like the originals were. That was probably 20 years ago. New ones are still smooth as glass, and as stated, were quite inexpensive,

Thanks for the info on the drum rotor size. Imma see how much cables are and see how hard they're to replace.

I had to replace the front cable on my 1992 (from actual e-brake pedal) and the long guy from the end of that do the adjuster...maybe spent $30 for both. Reading this, I may as well replace the other two into the drum assemblies while it is all apart for service so all will be fresh. I really expected those cables to be high dollar, nope! Only odd part I recall was trying to find the correct length due to the various cab and bed combinations available. ECSB has the 139" wheel base and the ECLB has the 155", no clue on the CC and RC.
Good thread here.

The one in the cab and to the assend? Maybe an hour. I have owned these body trucks since 1999 I think, so hip with how to tear them down fast and rebuild. Maybe for a new guy I would expect a few hours. I have yet to do the rears into the drums, but those should be easy since the 92 is in the air on jackstands.
This chassis was designed in the 1970s, do not overthink it.
