Trying to trouble shoot my warped rotors. My dyna seems to drag its pads continually, (not under pressure) and is audible by adjacent fellow riders. I was told this normal for this type of caliper system, but my wifes identical bike does not have this problem. Of course she has stock wheels and I have the aftermarket wheels.

The pads on disk brakes are NOT supposed to have any clearance (although very little squeeze should be on them at rest). If they are only rubbing on one portion of the wheel the rotor could be warped. To check for sure, remove the disk from the wheel and place it on some VERY flat surface (clean granite counter top, or a window) ; gently holding the rotor against the surface tap on various places with your finger. If you the rotor rocking up and down, you then know you have some warp. the most accurate Way to measure warp is to use some feeler gauges (thin calibrated metal strips-super cheap available at any auto store. Try to place gauges between flat surface and disk while gently holding it down. the largest one you can fit under without actually lifting up the whole disk is your warp/out of round/runout etc.

It relies upon on the situation of the rotors. If the rotors are mushy and have not wore skinny then you definately do no longer might desire to substitute them. they want to sell you rotors quite of resurfacing them because of the fact is maximum situations that's extra low fee to replace. while paying for pads, purchase the semi-steel, which will desire to be the middle grade. The decrease grade does not final long and the better grade (steel) has a tendency to placed on the rotors. in case you do no longer replace the rotors, there will be a 'ruin-in era' on your new brakes. they might tend to act humorous until eventually the pads placed directly to the outdoors of the rotor. good good fortune

To check for warped rotors, jack up the bike just enough to get that wheel off the ground.
Hold a pencil (it's soft and won't damage the rotor) up to the rotor and spin the wheel.

Yes, there is supposed to be a clearance.
Brake pads should not drag on the rotor, or be audible. They are wearing out the pads that way.

They do, but you may not be able to see light through that small space. It's measured in millimeters, and should be. You wouldn't want to have to depress the brake all the way, just to have the brakes engage, would you?
