Put some Temp paint on the rotor's....start at 900*degrees and do 1000*, 1100*, 1200*degrees.....(paint a H on the vent exit holes of the rotor) that will tell you if it is a fluid issue or some sort of piston movement .... I've never used a residual valve.... and you shouldn't have to.....

If the pedal went down.... there's only 2 reasons ....Temp of fluid....or air in lines.... other than piston movement from a rotor or caliper movement..... many times the Heat will cause them to go down but stay hard as a rock.... is so it may be M/C size....It takes heat to make the brakes work like they should.

I wouldn't think that you are using the rear brakes that much.... when we balanced the brakes we would shoot for 1100*-1000* in the front and about 900*degrees in the rear....

Also bring your rear rebound up a couple of more notches.... this will help rotate the car on entry and maintain it in the middle and exit of the corner....... maybe soften bump on front one notch to get it to stick just a bit better...

Hope some of this makes sense and helps
