Having rec'd. many fine suggestions from Stan on his site and from emails to him, along with reading all the brake related posts here, I just want to ask if any others have experienced this on their Tanks (or similar body scooters), and if they spin the front wheel while up in the air, does it move freely. I'm hoping more miles willl solve this, but I am noticing a worn looking spot on the left side of rotor, and the dragging is more of a spin-freely then drag situation. The rotor looks too thin to turn, but I guess that is possible. With about 500cm on it, I had hoped it would turn free by now. if I loosen up the 2 caliper bolts a bit, it turns freely, so I am thinking the caliper is out of line with the rotor. If you have had this situation on your scoot, please let me know at what miles it got better. Thanks!

Loosen the front axle bolt. Tighten it to just snug. See if that helps.

I'll give that a try. Maybe the 3 foot pipe I put on the wrench was too much torque? :~) But, as I said, when I loosen the caliper bolts a bit, the wheel spins nicely. If the big nut (no, not me) on the wheel was over tight, then wouldn't the wheel be binding even with caliper off ?

First, I would make certain there is some anti-seize lube on the pad retaining pins so they can move freely. But-
I'm actually working on a permanent fix to sqeaking brakes for those of us that have two pins holding in the pads. I put new pads on my scoot just two weeks ago and I've had much more squeaking than before with the old set.
I bought some coil springs that fit the diameter of the pins. The plan is to install the springs between the inner & outer pad, with the pins going through the springs and into the caliper like always.
A. This will increase the lever pressure somewhat, since the springs will have to be compressed each time the brake is activated.
B. Its obvious this will be a PITA to fit together. There's not much room to work between the 2 pads to negotiate a coil spring.
C. The springs should push the stationary pad back away from the disc and reduce or halt the dragging.
It might take me a few days to get it figured out and photographed.

nate;
Interesting idea but be careful. You certainly don't want stiff springs or ones that wouldn't compress enough, blocking the pad travel.

Update on Front Brake Still Dragging;
Removed caliper and took it apart. Sanded pads to remove glazing. Looked at slide pins and they looked DRY! Applied thin coat of high temp grease and re-assembled. Installed caliper. Tightened all bolts. Spun the wheel. Finally...spinning almost as freely as without caliper on. What an ordeal! I guess the grease or whatever from factory either dried up or was not applied in sufficient amount. Anyway, easier scootin' now!

I lubricated the the pins and the retaining spring with hi temp nickel never seize and now no more squeeeling brakes. I also applied a little to the rim of the piston |
