How do you adjust the parking brake on a 1992 Chevy Lumina after installing new calipers?

Answer 1

I replaced the rear calipers on my 91 lumina and I recall wanting to do this too. I think if you follow the cables and look for a grommet that's about 6 inches long. But I don't recall if that adjusted the length of the "throw" or if it merely adjusted the right vs left rear brake so as they could both work together. Anyway, this grommet is a thing that you spin. It has threads on both ends where the cables go in. As you turn it one way, it shortens on both ends and "shortens" the cable. Turn it the other way and it lengthens the cable. I'm not positive of this. I recall seeing this grommet but don't think I actually turned it. If I recall, I believe I ended up doing nothing because the parking brake pedal is a "pumping" type...meaning you push it to the floor and if it isn't tight enough yet, you release your foot and then push it in again. You continue "pumping" it until it's tight...like a ratcheting effect. Now that I think about it, I'm pretty sure you don't adjust the "length" of the cable...you simply pump the pedal to take out any slack. And I'm pretty sure the grommet was an adjustment to make both back brakes hit at the same time.
