Sorry indiemo, but during my time in Denver, I found ALL of them to be horrible. Downtown, Parkway Auto did some brake work for me, and didn't bolt my master cylinder back on. I almost died driving thru an intersection in Littleton with my buddy Steve. It seems the threads of the bolts were giving just enough grip to hold on to the cylinder, allowing me to drive 20 miles (by freeway) to Littleton. Then all of a sudden...no brakes!!
I'm lucky it didn't give out on I-25!
Never go to Parkway Auto on 21st and Larimer.
