Question on brake noise
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?

Make sure you have no
Make sure you have no excessive drag on the rear wheel, rotor to pad, after pedal adjustment....Heat warps rotors...Harley one piece rotors are junk...As is most of their parts....Should you have a two piece rotor your a little better off
The new composite that they
The new composite that they are using for Harley brake pads is more metallic than the old. I've heard that they are coming out with what is called an anti rattle pad. It's a thin membrane that is put between the pad and the piston to stop that kind of noise... Until they do we have to live with the sound. It doesn't hurt anything and it lets you know you have the longer lasting pads.
My 2 cents. Ok weight impacts
My 2 cents. Ok weight impacts the problem. My thoughts, rear axle, seals, bearings or even suspension, as all of this things are impacted by weight. With the extra weight it seems the tire goes side to side impacting the braking/ pressure. It could even have something to do with the caliber. Any more specifics would help narrowing it down.
