When this is happening, pull over and feel your wheel to see if it's hot. You could have a sticking caliper or restricted brake hose causing the problem.
This I don't understand. Are you talking about the three prong clip that goes into the piston cavity? Replaced it with what, another pad? Can you provide a picture of that pad? There are two systems used on the Generation 4s (TRW and Teves), Teves if you have rear disks. Are there rights and lefts to your pads. My Jeep, for example, has a left set set and a right set for the front, a two prong connection at the bottom and one prong at the top.the inner brake pad clip the it fits into missing on the top. I went down and got another one and installed it. Looked everything else over, and reassembled.
