I just put on new front brake pads and they are draging enough to slow the front wheel down when spun on a stand. The old pads were worn evenly and did not drag at all, the rotor and wheel appear to be true. I have not bleed the line yet as I am waiting to borrow a friend's pump. Will bleeding the line help? I was going to remove the pistons and clean them in some brake fluid. The manual states to replace the dust seals. Is this nessary if carefully removed and they are in good shape? I can push them in with my thumb with some moderate force.
