Probably quite a few of those in the Upull yards.

Hope everyone had a great Christmas! Been kinda busy and haven't posted much, but have done a lot to the Tahoe. Finally bit the bullet and purchased a Blackbear tune, front and rear pads and rotors, steering box (didn't fix the inch of play in steering wheel). Along with a t-stat and coolant temp sensor yesterday. It was weird timing that the fans seem to all of the sudden be blasting away after the tune. But once I sent them a follow up log (all data was good). They suggested it could be a t-stat. Then I thought, since I am already working in the area, let's do the valve cover gaskets since they were failing. Of course, my wife's Tahoe didn't have the petcock valve, so I had to remove bottom hose. Fans aren't running now, yes! Even have cold and heat coming from passenger side vents for now. Another item on the list is the blend motor behind vent...

Did my first oil change on the 02 Yukon, surprised to see it uses only 6 qts.. given that the newer year models use 8 qts.
Prior oil change had been done at 87K miles, I was at 91.5K. Refreshed to see no oil usage at all (I pour a quart or 2 between changes on one of my other trucks with a rear main seal leak, haha), oil color looked about the same or slightly better than Wife's 2024 after 4K miles (GDI and short trips
)

I still haven't had time to look any further into the brake situation. What else would cause a soft pedal that goes almost to the floor?

New head gaskets and extracted broken exhaust bolts

I’m no expert but would have to think there’s either air, or a leak, in the system.

It does have a leak in a rear line, but I'm not completely sure that's the sole reason.

Yeah you gotta fix that first, it doesn't make sense to me to troubleshoot further until that is fixed and then test the brakes to see what you have
If this is on your 2003 and you have all the original steel brake lines, they need to be replaced unless you possibly live in the SW US where it never rains or snows.
Most of the original steel brake lines do not last much beyond 10 years on anything up to about 2006 when they went back to plating/painting the steel brake lines.
