99 suburban k1500 6 lug drums

Both sides the shoe with the less coverage faces towards the front.

As they should.

These shoes release alot of dust, would the ac delcos not be any better?

I don’t know if they might be better.

I’m accustomed to seeing a lot of dust in drum brakes, and I routinely pull the drums and clean them when rotating the tires. Maybe that’s just me…

I did not measure the pistons when I replaced JN3 calipers with JB5/6 calipers. I do not expect that they "neck down" to any significant degree, though. Some, not a quarter-inch.

My concern is that with the smallest part of the piston being less than 2 3/4", he's got the tiny-piston JN3 calipers.

Again, Raysbestos is Acdelco supplier, so they are the same.

Rear brakes cleaned up, ac delcos shoes are in, drums are painted and drying atm.. tomorrow will install and adjust.

This is the passenger side.

Is this normal for the axle shaft?

This was covered very recently in another thread, now where is it...

oh yeah, here, with very recent posts...

Play In Rear Axle Shaft

About 8 months ago, I noticed a little of in and out play in my rear passenger side axle shaft. It has just enough play to blow the axle seal allowing gear oil into the brake drum, ultimately making my rear brakes stick. The left (Driver) side doesnt have as much play and doesn't break seals...

Nice! Well my seal hasn't popped so thats good. I just put in $200 on the rear brakes so I will ride that bit of play until i can’t. I have the 10 bolt diff so my plan would be to upgrade it to the 14 bolt diff axle in the near future.

Rear brakes are done

I get new rotors on Friday, going to start prepping the wheel well area for cleaning and painting on Thursday.

I ended up going with Detroit Axle rotors, slotted and drilled for $95 shipped. They have a 10 year warranty , if anything happens with them in the first few, ill go with the EBC ROTORS. They weren’t available until April 5th, so i had to make a decision

With this being said, what are some recommendations for calipers? I get my rotors on friday and want to purchase a new set of calipers tonight so they’ll be here by then

RockAuto.com, check your year and look for calipers for JB5/JB6 brakes. If you click to look on the calipers' specs, you ought to see either "3in" or "76mm" in the specs (if the spec is listed, sometimes it is, sometimes it isn't).

(edit: After looking myself, it appears the distinguishing factor for the front calipers on RockAuto's site is whether the vehicle has "13in Rear Drum, 8 Lug Wheel" or "11in rear drum"... the 11" rear drum was used on 6-lug Suburbans and employed the 3in / 76mm "low-drag calipers" up front on 11.6" rotors, while the "13in Rear Drum, 8 Lug Wheel" Suburbans employed a larger-bore non-low-drag calipers on 12.5" rotors)

You can buy them where you choose, but RockAuto is a handy place to browse and compare.

I usually buy Raybestos, and reportedly ACDelco is rebranded Raybestos. Barring those, I try to stick with the "name" brands... Bendix, others.

Take a look at the Raysbestos Element3 calipers.
