I did have one issue when I installed them and one caliper was missing the two anti squeal/rattle clips on both ends of the pad ,
look to see if you might be missing them,
also call summit the will have alot better customer service and can answer questions or problems about Wilwood since they so sell them,
sorry you are having problems , they are a lower brand as far as costs ,but I have had no issues with them,bummer for ya missing those shows
