With my 1998 Chevy I replaced the OEM rotors and calipers and pads with the best aftermarket parts I could find on the internet. I did this at 28,000 miles and put another 150,000 miles on the truck with only new pads at 80,000 miles. Labor cost was the same and the parts were no more expensive than the GM junk from the dealer.
Made no sense to replace obviously poor performing GM parts with new GM parts. Lots of aftermarket brake components for the Chevy trucks of this era as it is a common defect.
I did the research as to the best parts and bought them online. The garage mechanic is going to call the local parts store and get whatever the clerk decides to send. It was worth the investment of a couple hours of my time to get the best possible brake components as it paid off over the miles and years I had the truck.
