Disc brake drag....

How much brake drag is acceptable for disc brakes? I know there has to be some,but how much?

Ever since I converted to discs it seems as if I get excessive brake dust. I even tried ceramic pads to help with the dust problem. This did help,but it still seems like I get too much.

Re: Disc brake drag....

clean your calipers maybe. If you have too much junk the pistons wont retract enough.

but if I spin the rotor it wont make a full turn before it stops.

Mine will make at least a turn so maybe they're ok?

Re: Disc brake drag....

disc brakes do not require the same amount of "drag" as a drum system due to the caliper having more hydraulic cylinder "travel" versus the smaller wheel cylinders on a drum system.

Re: Disc brake drag....

Hey Royo, when you say 2 lbs on disk and 10 or more on drums are you referring to foot pounds? What is the best way to measure that?

I think he is referring to residual line pressure.

oh ok. I thought he was talking about the amount of drag you should have when adjusting brakes.
