Ok, so today my AL friend dropped off her 2005 Tahoe LS for the brake pedal upper bushing. There was a severe rattle from the pedal, under dash area, when went over bumps.
No pics from underneath because was just too crowded and there is a few videos at you tube to look at. Here is a link to a good one:

I took the driver's seat out and laid under there and reached up but was still very cramped. Hard to take apart the pivot bolt but all nut and bolts removed, including at seat, were thread chased and was way smoother going back together. The pivot bolt is 18mm at each end. The seat nuts at front take an E18 and the back bolts take an E14.

I also installed a new brake light switch. Everything went to plan and was a 3 hour job.

You can bet it rattles too but you may have tuned it out. When it was all back together it had no movement and pivoted freely. The video tells it all and is a good time for a new brake light switch. The seat removal is your choice but the job would have been a "no go" for me without removing seat. The actual bolt removal and bushing replacement is a cinch. It is the access that makes it a bit rough. The two ears that the pedal pivot fit up in to, are tight enough that with the new bushing width, the pedal can be wedged up in there and will hold itself so that you can slide the bolt in. The bolt has a shoulder at the thread end. That is where the bolt stops when pushing thru. I cannot stress enough to chase all threads for reassembly. Makes the reassembly way easier.
