4 Piston Big Brake Upgrade from 2019-20

[Kermode]

Resurrecting this to ask a question - has anyone measured how far these calipers "stick out" from the hub face? 65 pages of thread and I couldn't find it. Marked in red from someone else's very good photo of the install. If we knew this distance it would probably help with the "will my wheels fit?" questions, as you could just stick a tape measure in there and see if you have enough clearance.

Ok...Finally got a chance to get out there and take some pics, but I apologise for the delay as my back has been, I'll just say, less than cooperative. I had a straight edge and checked measurements but couldn't take a pic holding both by myself but these are the measurements. If you were to shave the hump off, it's 1 1/4 minimum to clear....If you don't shave the hump off it's 1 5/8 minimum to clear. Rotor to spoke varies on my wheels as the have more clearance as they go out. And for reference cause it was asked...my wheels are 22"x 9" with 31 offset. Hope this helps!

does it need the SS brake lines I’m trying to set this up on my 01 with serious lack of brake power

You don't NEED stainless brake lines, but they won't hurt and will help with peddle feel as it will be more solid. I had already replaced all mine with stock lines as the old ones were not looking so hot. When I did this swap, I kept the rubber lines so I could do a straight comparison from nnbs to 4 pot calipers as far as braking and feel. I now have all stainless lines and the peddle feel is definitely more solid.

can I copy and paste those brake lines onto these calipers and my 01 Yukon xl , is this all I need besides washers?

I think you still need 1 more item. The bracket that holds the caliper on. In this tread there is a complete parts list.

This is majorly helpful!

Nope!!! there isn't a bracket as these are not floating calipers. They bolt directly to your hub/spindle! YAY!! cost savings!!! lol!

You are correct. I must have been thinking nbs to nnbs.

Got a set of take-off calipers and rotors and just did my test-fit. I can say for certain that the 20" Denali wheels clear all of this without the slightest issue! No wheel spacer, no caliper shaving. There's at least a half-inch clearance between the spoke and the "hump" with the caliper properly centered on the rotor.










I think I'll paint these calipers glossy black with a DENALI logo before I do the full install. Booya.

Would it be possible to confirm that these are the OEM 20" snowflakes, correct? GM PN: 22977696 20x9 +27 offset

This are not the snowflakes
