Parking Brake - NOPE validation request

Dug into my ‘86 K10 and I’m thinking the PO put the parking brake equalizer together using a few spare parts that might not be correct.

The enclosed pic shows the current config (ignore the cut cable, it was frozen) and I don’t see how the equalizer pulls both cables configured this way. From what I can tell only one cable (driver) will be pulled.

I checked LMC and really can’t tell how the equalizer should be configured. I did however order new cables and associated parts (including a new equalizer).

Anyone have experience/pics?

Re: Parking Brake - NOPE validation request

That is correct, other than the zip tie. It just looks odd. There is a limited amount of equalization between the two sides which is why one cable is adjustable. When the pedal is depressed it pulls the lower pass-through cable and triangular bracket toward the front until there is tension on the upper cable. Then it begins to pull the lower cable. This is the adjustment procedure from a manual I have.

Quote:

Adjust brake shoes.

Apply the parking brake 4 notches from the fully released position.

Raise and support the vehicle.

Loosen the jam nut at the equalizer.

Tighten or loosen the adjusting nut until a light drag is felt when the rear wheels are rotated forward.

Tighten the check nut.

Release the parking brake and rotate the rear wheels. No drag should be felt. If even a light drag is felt, readjust the parking brake.

Lower the vehicle.

If a new parking brake cable is being installed, pre-stretch it by applying the parking brake hard about three times before making adjustments.

Thanks a lot for that!

The word “equalizer” threw me off my not so good game!
