disk brakes history question

[Selo]

I just bought (1200 miles so far) a 2019 Silverado 1500 LD Legacy WT with full trailering package. I was installing fender liners and mud guards and noticed to my happy surprise, the truck has 4 wheel disk brakes. I had no clue.  I have not seen one list of features for the model which indicates 4 wheel disks. Could one of you fellows educate me as to when 4 wheel disk brakes became standard equipment on 1500 work trucks? Pretty sure my 2010 1500 Silverado WT with trailering package did not have them. Pictures are prior to liners and mud guards.  Towing mirrors got here today. Is this a sleek looking truck or what!

 

Thanks for any info you may provide. 

 

Cheers, Selo

Congrats on the new truck. In the half tons, 1999-04 had rear discs. They went back to drum in 2005. In the next generation (GMT900 platform), the Max Trailering Package trucks got rear discs. Then, for 2014 through today, they all have 4 wheel disc regardless of packages or trim level.

I'd forgotten about the 'going back' part. 

 

I do recall lots of issues with the rears on the 99-04 generation.

Yes. I was pretty happy that my 2011 came with drums in the rear after seeing how the rear disk brakes were holding up on other truck. I guess time will tell how the do on my 2019...
