Which pad would you recommend? I am look at the Heavy duty or LTS Pad from Hawk or the Performance Friction. I have read a lot about both and the Hawks get good reviews but the PF sounds good due to it having no fillers. This is going on a 03 Yukon that does no towing. I live in Florida but could be moving to the mountains within the next year. Any comments are welcome. Factory brakes do last a long time but the performance is not good at all. And they are starting to pulsate so I figured with taxes coming I would just replace everything to pick up some safety and get this done while I can. Vehicle has 73K on factory brakes. I know they can last longer but I want more performance. I let my parents drive this on a trip to Nebraska and my dad said the brakes were terrible coming down mountains, and yes he does know how to drive through mountains.
