Sweet! But the real question is, how do they feel?? Tell me a little more about your setup. New rotors, pads, and of course the calipers?

I just wanted to make sure they fit before I even though about anything else lol,  I actually got these Barley used, and barely I mean the donner truck had 1 mile on the odometer lol, so I got everything, loaded calipers, and both rotors, I’m going to try it in “stock” form and then upgrade pad and rotors as needed, I’m just stupid happy they cleared my wheels

BUMPING this thread up to see if anyone else has feedback.

Hey Bud. Just got done doing the swap on my 2006 Z71. Here are the measurements roughly. 

 

Front face of rotor to outer edge of the caliper is 2-1/2" roughly.

 

From face of hub to outer edge of caliper is 1-1/2". If concerned about clearance add 1/16" to your figure.

 

I have 2015 Sierra 20" oem wheels on the truck. Tons of clearance with these.

 

 

I would love to do this on both my 02 Tahoe and 13 Denali XL. 
Was it straight up plug and play or how big were the spacers you had to use

Having a 6.2 I cannot say my brakes (in their current state) are confidence inspiring. I have an NBS silverado that I converted to hydroboost and it's pedal feel is fantastic. 

 

I'm going to flush my fluid this weekend and that should help my pedal a bit. I'd like to get more feedback on this topic though throwing money at my current setup. 

can you provide more info on your hydroboost setup?

I used the hyrdoboost pump and pressure line from a 2003 2500 van. That's the only 3/4 ton GM vehicle to use a rack and pinion as far as I know. That's important because there's 2 hoses that complete the circuit. One from the power steering pump to the hyrdoboost, then from the hyrdoboost to the rack. It also needed a brake pedal from a 2500 too because the rod coming out of the hydro unit is different than the vacuum unit. At the same time I put a brand new PS pump from a 2500 on it too since it already has return line nipple on it. 

 

Overall brake power is much improved. No more sponginess! With the old booster functioning as designed it took quite a bit of pedal travel for it to even do anything. Now it has about 1" maybe of slack (which is probably because the hydroboost is used from a salvage yard) and then it gets real firm real quick. 

 

All in all, I'd say it was very much worth it but it was quite thorough. That was before I was married and had kids so I had a lot of free time.

I have two stainless steel washers spacing it out right now I’m working on machining a one piece.Im pretty sure I’m the first person in the country to do this so far and I can tell you the calipers more then make up for the lack of rotor size it has a very firm peddle as well best peddle I’ve felt on a GM truck 

Have you made the stainless washer ? 

[evoe46m3]

Can someone measure the piston diameters of the new brakes. I am curious what it is.

[soobie99]

Hey all,

Can someone please confirm that these calipers fit (without modification) a 2017 z71 with oem 18” wheels? Post pictures if you’re able. Thanks!

Hey been looking online and can’t seem to find these calipers anywhere. I was literally on Rock Auto site and tried adding to cart and they disappeared.

Anyone know what length spacers you need? How thick of washers and how many? Everything else has been discussed except that and I’m really wanting to do this upgrade on my nbs Sierra. Also do you reuse your factory caliper bracket bolts or the ones from the 2019 caliper?

I have a 2018 with 20” rims and didn’t use any spacers. Reuse the bolts that came off your truck and I’ll have to check on the washer thickness but it isn’t much. Maybe 1/8”.

So you don’t need a stack of washers to center the caliper over the rotor? Just a regular washer on both bolts and that’s it’s? 

[lucas287]

BUMP - strongly considering this upgrade! there are now quite a few YT videos on the topic and @Gsmith308 that's correct, just one or two washers is needed to center the caliper.
