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

My '10 PPV has 13.5 rotors on the back; confirmed that over the weekend while exploring some options

Are they single or dual piston? I know my NBS rears were dual.

Single, that was the reason for my inquiry. I'd like to upgrade the rear calipers

My 2001 rear calipers are dual piston.

My 2012 rear calipers are single piston.

The 2001 calipers are shorter in length then the 2012 caliper though.

How do I check my ethanol % with my Tech 2?

My 1 tank of E85 has dropped my MPG like 30%.

I checked my Ethanol level and it read 60%

 

[1BADI5]

Yeah my ethanol sensor in my truck is stuck........reads 23% at all times

It’s weird to me that the NNBS rears have a bigger rotor than the NBS yet they’re single piston while the NBS are dual piston with smaller rotors. It seems to me the NBS dual piston would actually be better even though they have smaller rotors. Thoughts?

I don't know if they would or not. I do know that on my 2001 I go through rear brake pads quicker than the front pads. I always thought the brake bias should be higher in the front than rear, but it seems to be opposite on it. Maybe that's why they changed the caliper style on the NNBS

She was speechless, figuratively and literally! That was the part of the video right before she was holding her stomach.

This is the part that makes me unable to wait for her to start driving. The thought of paying insurance kills it, though! I'm hoping she'll accompany me under the Tahoe for the oil change coming up in 600 miles. She's such a bookworm- maybe I can slip in some custom car mags for her to read. Maybe we can nerd out on sound waves and calculating enclosure volumes for the Tahoe's sub system.

Tell her you need help with some math. Crunching numbers for the mpg or some assistance getting the tuning dialed in. Kids always like helping when they can teach something new to the older generation.

Not trying to pry, but have any of you guys with kids (in their teens) thought about or looked into building their credit? Credit score, and the fair issac corporation (fico) score weigh heavily in the cost of an insurance premium. Most drivers under 25 don’t good or any credit, but their adjuster never bothers to tell them that they can lower their premium by having a better credit score.

My 02’ was different than your 01’. Mine had dual pistons and the rotors were smaller than my 11’. I never compared the height of the OEM rotors, but I know the aftermarket are thicker and taller.
