In regards to the break fluid, I did not do anything. If you think about it, everytime you step on the break, the two little cylinders inside the caliper move in and out. Do you bleed your breaks everytime you step on the breaks? No. I took a "C" clamp and used the old break pad to push the two cylinders in just enough to get the new pads on. It worked perfectly. A few of the bolts around the caliper where a "B@*#H" to get off. I had to make a breaker bar to put on the wrench. I did not service the calipers. Just remember to use something to hold the calipers once you take them off. You will see that I used a bungee cord in one of the pics. I used Hawk break pads. I will say that the Hawk break pads cause more dust then the ones Chevy uses. (Sorry Hawk!) They have great stopping power but unless you like to clean your wheels everyday, use something else. Let me know if you have any other questions. Good luck!
