Low Rider

I own a 1998 Harley FXDS-Conv. Recently I have had a brake problem. The bike has approx. 38K, I put 20K on the bike myself, it was under extended warranty for 2 years, when I bought it used in 05 from a Harley Dealer. A little background, obviously I am not mechanically inclined and have almost all my work done by Harley or a Harley certified mechanic with several years experience that has his own shop after working at a couple of dealerships.

Recently, I had a rear brake rotor to warp. I replaced the rotor and pads, the brakes work fine, except for one symptom I encountered previously. Riding by myself, no problems. Riding two up, I cannot apply rear brakes fully, I hear a grinding nose (when rear brakes are applied only). Riding by myself I can lock the tire, no grinding. I had this symptom once before.

Approx. weight with rider + passenger 390 lbs., a little of a load on a Dyna, but it did it for over 2 years without this problem.

This spring I had a rear tire replaced, and had the brake pads replaced, I do this approx. every other tire change while I have the tire off. There was a problem with the brake pedal, two much play (pedal).

I went back and had the pedal height adjusted. The problem started after this. I had it checked out again before the rotor warped, they found nothing. Looked for suspension problems 2 up, or source of the grinding noise.

I suspect this was related to warping the rotor. Could adjustment on the pedal height cause this?
