What did you do to your NNBS GMT900 Tahoe/Yukon Today?

Fless said:

Good question. Came across the same issue while doing some research for the NNBS upgrade on my NBS, and I'm still wondering. Here's what RA shows for a 2010:

EDIT: Most hardware seems to be the solid clip; here's the difference (square hole on bottom pic):

When I put on the GM heavy duty brake calipers/pads last year I believe they came with clips that look like the top pic

Those seem to be the most common, and I'll probably go with them when I get my brake parts later this spring.

When I bought factory pads for my 2012, also top pic clip style..

Fresh out of the spa.

For $10 I would have kept the old if it was still in working order.
Also, is it just the color of the pulleys or does the new one have a larger pulley?

Unsure, sounds like the design and materials changed per Montie's subsequent response

Replaced the 15% front door tints with 5%. Looks 100% better. Flows well with the black paint and 5% tint already on the back windows

Yup.. the pulley on the new one is made of a solid aluminum, so it is thicker, but the diameter is the same ( of course )
The old pulley is steel... ...thinner.

from what I recall I thnk someone mentioned there being some difference with the brake pads in 2007-2008, might only be certain models, that had a different caliper with a smaller pad mount (i think)
and that regular pads would not fit.
it's posted on the forum somewhere probably in this thread but it's been a while since it came up
might not be related at all but that's all I remember about brakes being any different, some kind of one off thing
@swathdiver might know

There are two different pad sets, one without Active Brake Control, JL4, and one for use with JL4.

In 2008 a 2nd design of each type came out with pad spreading finders on the clips. So for 2008, you'll often see all 4 types.

For 2009 and later, you might find another set listed for JL4, 19421276, I think this is the copper free set.

Makes perfect sense.
Thanks.

Installed some LED headlight bulbs, Auxito H11 https://www.amazon.com/dp/B0CMCLYN8S

This photo shows the cutoff, so far I'm very happy with them. They were smaller than I expected, look well made.
One of them wasn't quite clocked right looking at the tabs. It came with a small allen wrench and I adjusted one that looked off.
Barely fit on the driver side, little more space on the passenger side somehow.

About what I expected/hoped, definately brighter, whiter. Easy as changing bulbs! Being un-tested, we'll have to see how long they last..


The edge lines in the photo are representative of the spread/cutoff/pattern. I don't really see the extra bright oval blob as the photo. (Or they aren't that blinding!)
But you do see the two brighter 'rectangles' that the ovals are within.

on street.. adjusted to not beam oncoming hopefully..
