2021 PPV Front Brakes on 2013 Escalade ESV, and rear brake overhaul

[Davidj281]

Seth, wanted to offer my appreciation for this thread on how to do this awesome upgrade. Your work is impeccable. It is quite a step up from stock and well worth the upgrade. Thought I would also discuss what I did/used for this job. Calipers/rotors/stud/lug nuts from Rock Auto.

1. R1 Concepts Drilled/slotted Rotors: 631-47091L, 631-47091R
2. Pads: BENDIX PBD2407 Police
3. Studs: Dorman 610-530.1, I didn't push the old ones out like you did, I just whacked them with a 3lb hammer. They came out pretty easy. Installing did require an some heavy nuts as washers and an impact gun.
4. Banjo Bolt: I ordered qty of 2 of M10x1.0mm x 24 mm Metric SS Single Banjo Bot w/washers, used this instead of cutting GM banjo bolt like you did. I have SS Brake lines too.
5. McMaster Carr Washers (18-8 SS Mil Spec Washer, 5/8" Screw Size, NAS 1149-C1063R 98017A215: Used 4 of these washers, 2 on each bolt of caliper to line them up over rotors. Thanks n8in8or via thread #42!
6. Used the same wheel spacers; mine rubs a bit on a hard turn in because of my mud flaps but i can live with that.
7. This upgrade makes you realize that you have very capable brakes!

Thanks Again. Now i'll try to figure out the Aluminum front end parts that Pete did as these rotors are quite heavy. Calipers feel lighter that the stock ones though.

Man, you guys are holding out on me. Didn’t know the Brembo 6 piston 410mm / 16.25” discs were now being manufactured in Drilled, slotted & zinc plated. Now, finally we can get some decent life out of these rotors without all the brake material build up / warping that caused all that pulse in the pedal.

Welcome Gen III 07-14 front brakes and suspension to the Gen V 21+ world, finally, bolt on OEM stopping power with Brembo as a factory option.

I wonder if newer model knuckles will bolt up, eliminating the need for grinding and centering washers. ?

Kinda missed the question put up there. Modification of the Alum knucks for BBK, find out soon. Modify or not, they do fit.

15-20 / Alum / Newer model knucks are used in 09-14 z71 package and a few other oddball configurations like Hybrid and XFE package.

Yes, alum knucks can replace steel as long as the steel upper control arm / UCA is replaced with the matching alum UCA that has a different taper that matches the Alum knuck.

The alum knucks and alum UCA were used on & off during 09-14 and GM put them into play full time on 15-20 full size SUV.

The same goes for the alum lower control arm / LCA however, the Alum LCA fits EVERY 07-14 & 15-20 truck whether it has Alum or Steel knucks.

As stated before, if doing a BBK swap and you’re in the hubs, you can easily swap to Alum UCA, LCA, knuckles as well as the 6 pot Alum Brembo BBK and shave close to 100lb off each front corner of your truck.

I have all the parts to do it but I fubar my back at work and have to wait for the Indi to install this Winter. It’s frustrating literally looking at it but not able to do anything with it yet.

How about '21+ knucks and arms..?

In another thread someone got the wrong lower arm, supposedly a 15-20 tahoe lower arm..

Aluminum / XFE NNBS Front Suspension Rebuild

Got mine today :) I am absolutely amazed at the weight difference between the two. On the hunt for some 09-13 Hybrid or 15+ tie rod ends now.

Good question about fitting the 21-Present knuckles, arms and ball joints to our 07-14 trucks. Good pic you referenced on the 21+ aluminum control arm not fitting a 15-20 aluminum knuckle.

To make it more Kra-Kray you have to remember this is in regard to fitting only 15-20 aluminum suspension parts on 07-14 full size SUV

Well I guess I screwed up and got the wrong lowers. Ball joint are too big to fit into my drop spindles. I guess I can either sell or try and send these back or order some drop spindles that will work.

above pic is a 21+ aluminum control arm that won’t fit in a 15-20 aluminum knuckle that was installed from factory on some 07-14 full size SUV.
