Working great installed on my 2004 Trailblazer LT. All "hard parts" for the brake job came from Amazon:
A word about OEM parts: AC Delco is a GM subsidiary. These guys make many of the parts being put on your vehicle on the assembly line...
Fitted these to my '03 trailblazer this spring ('14) No issues with the arrival of the order or the goods in question. They were a straight fit to my trailblazer and went on smooth. Also ordered rear rotors and brake pads ... all good. Some issues with fitting the rears (not related to the product but the truck)
The rotors are not treated in any way for after fitting rust prevention so after 3-4 mo's some rust started to show on the new rotors, but then again we're talking brake rotors here so that's just expected. From the box there is a light coat of oil that you'll want to clean off with some brake parts cleaner before fitting.
Should you really desire to keep your rotors looking new you'd possibly want to paint them, personally a rotor is a rotor so I never bothered.
Performance wise, they do exactly what they are supposed to, stop the truck. Since I changed all 4 rotors and pads at the same time its hard to judge the improvement from any two...
Purchased from Amazon Deals so I got a nice discount because the box they were in had a tear...Amazing deal as I couldn't get an aftermarket part at a price near Amazons. Put them on the next day and it took care of the pulsating brake pedal.. AC Delco seems to last many more miles than others I've gotten at auto parts stores. Very happy with this purchase. Fit 2002 Trailblazer with standard wheelbase perfect.
