I swapped my car to the big front brakes. #755

The caliper mounting bracket is different from the GM caliper to the Sierra. ERA supplied the new bracket. My knuckles are the ERA built units that are similar to GM units. I simply unbolted the GM style bracket and bolted on the newly supplied ERA bracket.

I am not sure how you would mount the Sierra's to a GM steering knuckle.
