First drive after brake upgrade, then - BANG!

Give the OP a break. He is obviously discouraged and the more he probes the more he finds and is now frustrated. I’ve been in that situation and it can be a bit overwhelming. To the OP, just step back and take a deep breath. After reading the advice given try to respond to the post as quickly as you can with as much info as you can. These guys are truly trying to help and are very knowledgeable and they get frustrated too because they want to help but they are not there
