Brake drag

I am getting ready to order the discs for my car front and back. I have Wilwoods on the front of Falcon and I get them shimmed so theres no drag but by the end of the night there is some brake drag.
I have heard some guys say they never have any drag. Are some brakes prone to more brake drag than others?? Lets hear it.

Thanks Tore

Something like that help?

Never seen that before, Might work, Tks Tore

no experience with that part but I could imagine if it pushes the Pistons back, you won´t have any brake at first and second attempt..

I think it doesnt push the piston back, just pushes the pad to the piston. pistons are pretty tough to get to slide in relatively speaking. We use a special spring kit on our rear pistons at work that holds them to the pistons, the seal inside the caliper pulls the piston back, but if the pad doesn't want to slide back it still drags, so the springs we have attach the pad to piston. I would assume that would be similar as giving sligh pressure back, make require a slight bit more take up on pedal, but im assuming you'll feel the it engage maybe and inch or 2 lower. Nascar uses this little trick of safety wiring the pads back to the caliper for qualifying runs, that's why they now need to pull up and stop before they start qualifying

When the brakes are hot and dragging I would see which way they need to be shimmed and try to correct it... Might be able to shim it enough to fix it.

My 4 piston Strange setup front and rear has been great though

Thanks guys
