03 Chevy One Ton Park Brake Adjustment?

How is the parking brake adjusted. I see no in cable tightener that I’m familiar with on my other prehistoric autos. My mechanic says that it is near impossible to do. I haven’t talked to the dealer yet. It must be possible. I need it because I pull trailers up to 10 ton. Anyone know how it is done?

The parking brake system on your vehicle has an automatic adjust feature. That’s why you can’t find any provision to adjust the parking brake manually.

The instructions would probably tell you how to use three special tools to get the axle out so you can even see the brakes. You will have to look in the real manual unless the Haynes one has it.
