Resolved Parking Brake Issues

[WTW]

When I bought my 93, the parking brake had no resistance on the handle when engaging. Got underneath and found the parking brake cable bracket was broken allowing one cable to move freely. The bracket in the driveshaft tunnel that connects the cable from the handle to the left and right rear drum cable.
Replaced that bracket and adjusted rear shoes but I have to pull the parking brake handle all the way up before it starts to engage brakes. And it barely bites.
There was no slack in the cables at the bracket so I assume there is no stretch in the cables.
I didn’t see any other adjustment points. Am I missing something?

If you have that much slack you either do not have the shoes in the rear brakes adjusted properly or the cables need to be replaced but my money is on the adjustment.

Shoes are adjusted to a slight drag. Im not a drum guy so not sure if that is the correct way to gauge proper adjustment but seemed logical.

Yup that’s the way you adjust them initially. Did you apply the brakes a couple times and then recheck them?

I did not. Just the initial adjustment. I’ll pull the wheels off and check it again.

My drum brake adjustment procedure: adjust till they drag while turning wheel forward, apply brakes pumping the peddle 2-3 times, check for drag, adjust if needed, drive the car applying the brakes several times, then back up applying the brake peddle several times so the self adjusters can work.
Now test the parking brake operation.

The secret to drum brakes is to adjust them as tight as you can , THEN back them off to adjust them...
Usually count the clicks when backing off then do the same amount of clicks on the other side
By tightening the brakes fully you get the entire shoe to seat before adjustment......

My 83 parking brake has an adjustment nut under the handle in the car?

They stopped using the adjustable cable in 1987. You can install one but between the ratcheting system in the handle and properly adjusting the brakes the system is pretty good. Cable stretch is only solved with new cables.

Thanks for updating me......

The handle will account for some cable stretch as it does have a self-adjuster. That's the racheting teeth part that most folks disable when they swap to rear disk brakes.

I would check to make sure the broken cable hasn't caused it to self adjust all the way up. Reset it down to low end of adjustment range as specified in the thread above and then adjust your drums.

I'll check the handle assembly as well. No broken cables, just the holding bracket. Haven't had time to tinker with it this week. Hoping to get it sorted out this weekend with all the advice above.

If the brake drums are too big (oversize from turning or just worn out)
The E brake will work little if at all even with the adjuster cranked up all the way
If the drums are within spec, replace both rear cables

Finally got around to this issue. Car was out of commission for a few weeks to prep for paint. Cables were bad. New cables pads and shoes and she’s good as new.

I love the feeling of an E brake with all new parts.
If you use it regularly the cables will not freeze up for 20 years IMO
