Why the stock exhaust, you may ask? Well because the old SuperTrapp IDS2 my bike came with sounded like a Cessna in a tin can and was probably too rusty and corroded to be repacked without disintegrating. Had a stock one come up near me for free and figured I'd try it out. I'll miss how light the SuperTrapp was though, got it weighing in at 4.4lbs which is epically light.

Either way, I gave it a go and was sad to return from a short ride and see some big fat melty burn marks on my rear brake line. It wasn't even an offroad ride, I hit the smallest little mound of dirt at a local parking lot and next think you know, boom, melted brake line. I'm going back out there now to set my preload to the stiffest it can be, which is 9.4 inches of spring length. Anything else I should look into?

Pretty sure the brake line is sitting in it's natural resting position, it's in the little bracket that prevents it from going any higher, but it's all the way up there, quite close to the exhaust. I used to be paranoid and had gently zip tied it to the bottom of the bracket, as well as wrapped it with a bunch of silicone tape. Guess I should have stuck with the paranoid approach.

Pedal's got free play and the piston pushes back in just fine after the rebuild, so I don't think it's a problem with the return port on the MC.

Rotor's a tiny bit out of spec at 0.014 inches of runout (limit is .012), could that be it? Pads are also worn a bit unevenly due to how the caliper was before the rebuild, nothing crazy though. Perhaps both of those things in combination is causing the friction? Any other ideas?
