Premature Brake Releaseby BASEwiki
A premature brake release occcurs when the stowed toggle comes undone before you intend it to. This can happen if you donít stow your toggles properly and the opening shock applies sufficient force to bump them off. Alternatively, you might bump them off yourself as you reach up for risers (to correct heading for example). This is more likely to happen when you use stiffened toggles.
