Abstract
A brake is disposed in a window frame. The brake includes a cam that causes the brake to engage the frame to resist movement of the brake. The cam is operated by a pivot assembly mounted in a sash of the window. A body of the pivot assembly slides into a notch in the sash and is retained by a detent. The pivot assembly includes an eccentric pivot bar that is received in an eccentric passage of the cam. The pivot bar engages a stop in the body and has a detent that engages a lip in the body.
