Park Brake
Hi Folks,
Finishing up on the previous owner's park brake rebuild.
He had all new shoes and internal workings replaced nicely.
But left the old, seized cables in place, which I just replaced with a nice shiny SS set last night.
Not sure how long it's been in between, but what should I expect for a surface finish of the inside of the "drum" surface of the rotors?
It's clear that there hasn't been any shoe-to-drum contact in a long time.
They're not crusty rusty, but their also not shiny smooth like the rotor faces.
Before I go adjusting the tension in the system and burnish the new pads, I want to know if I should get the drum inside surface machined smooth, or that this is not required for a park brake.
I don't want to ruin the new shoes or do some other damage to the system. Or even compromise the gripping of the park brake performance.
Thanks!

You should be able to get a good finish on the inside by taking some 200 grit paper and scuffing it. I really don't think you need to machine the rotors if there is no apparent damage to it.

REALITY CHECK.....those small ebrake drums in back of disc brake vettes are junk....about the only way to pass any fed/state inspection is to tighten the hell outta the cable, then loosen it up after the inspection no was in HELL a ~6" diameter drum going to hold a ~2500 lbs car from moving on much of any hill/incline....fizzicks sez so.....
