Cool, thanks Evan!

I am on the lookout for a complete set of 17" wheels & tires. But I truly love the way the truck rides with the current wheels/tires. The roads around here (Rhode Island) are absolutely terrible, the bumpiest, pothole-filled roads on Earth. My 16" tires have big sidewalls which really absorb the bumps nicely.

Just get 17" wheels and then get tires with the same sidewall height as you have now.

If you 'truly love the way the truck rides with the current wheels/tires.' then you'll just have to learn the love the way it brakes as well I guess.

Only other suggestions is to change the pad/rotor combination to find one that gives you a feel you like.

I still disagree with using police brakes. What I found was that the police brakes "are designed to be quiet" (so they aren't squealing a bunch of vehicles when they pull up to a location). They also have upgraded high temp seals, but do you really need the high temp seals for driving on the roads? Those are designed for a full tank of a high speed police chase.

They are a fleet vehicle pad, meaning they are expected to be inspected frequently. I also THINK that what "designed to be quiet" means is that the pads don't have that metal tab like all other pads, that is specifically there TO squeal when they are getting low to let you know to change them real soon. Without that, and without regularly measuring them, you might some day find yourself trying to stop with metal on metal rotors. Making those rotors junk too.

SOLVED - 'upgrade' rear calipers? '03 1500 with 16" wheels

Postby Chevy-SS [OP] » Jun 28 2021, 4:52pm

SOLVED!!!! Check out the pics.

I looked at the rear brakes, and decided they needed replacing, even if I just had to re-do the single-piston caliper setup. So I looked on Autozone web site and saw dual piston caliper option that was listed for my truck. I said to myself, IT CAN'T POSSIBLY BE THIS EASY.... but it was, LOL. :lol: I bought two calipers initially, then test-fit one. It was perfect. Then I bought the matching rotors and pads, installed everything meticulously, and it works wonderfully. All OEM style parts.

Brakes are a little stronger, not a huge difference, but I can feel a little more stopping power. Absolutely worth doing if you're re-doing the rears. If I had 17" wheels, I would do the upgrade to the fronts as well (from 12" rotors to 13"), where a larger diameter rotor would absolutely give more stopping power. Interestingly, the stock rear brakes already utilize 13" rotors (both in the BEFORE & AFTER versions), but the fronts are only 12".

Well, for anyone still reading, I bought and installed set of brand new Chevy 17" take-off wheels/tires. They were balanced and even included TPMS sensors. Cost was $1,150. They ride beautifully. I prefer softest ride possible, otherwise I would have bought 18" or 20" wheels. But the roads around here are terrible, so bigger wheels not in the picture for me.

Immediately upon making sure the wheels fit, I went to parts store and bought the OEM-style pieces to upgrade the front brakes from 12" rotors to 13" rotors (calipers, rotors & pads). I finally feel like I have adequate and competent brakes, what an amazing difference now. It's wonderful. :D
