I've just replaced my factory twin pot discs with wilwoods, i bought used. After bleeding them and lining the calipers up, i noticed they're dragging some, i can turn the front wheels by hand with the wheels off but they are reasonably hard to turn.
What could be the problem ?
Mick

mine did that too after i installed new seals. i ended up polishing the pistons on a compound wheel. there were real fine lines on the pistons. after i had the pistons lookin like chrome, they worked fine after that.

loosen brake line at caliper see if wheel turns easy, if it does you may have a residual valve in your master cylinder which was used for drum brake applications.

Thanks Rick, do you mean a wheel for buffing paintwork ?
Ratpatrol The car came from the factory with discs, it's a Dart GTS but on second thoughts, it has got a newer master cylinder, steel with the plastic pots on top.
Cheers Mick
