I think this has been asked, but Im gonna give my situation and see if its the same. I want some information on the Volvo brake systems for one. I understand that they are sliding caliper, and it looks like they use one caliper per brake, I would think they would use two, but whatever. I have on my car the Power Slot Rotors and pbr brake pads. I also have the Steel braided brake lines, but I need to install those still. I have had them for 2 years now sitting on my workbench, I know its sad. I bought all the stuff on an IPD brake sale, they had all the stuff at a good price. Anyway, my brakes have squealed bad ever since, and as things wear, it seems to get worse. I used to think it was because the pads had to warm up, but I think it gets worse with warmth. It only squeals when at a certain point, its not about brake pressure, it does it from when you first press the pedal to when you are almost stopped. I had that brake squeal goo put on them along with the shims in the rear. I have been assuming its the pads and I need new pads anyway. Anyone know what the problem is? Should I get the PBR pads again, or are others like the EBC pads a better choice? Any suggestions would be appreciated.
