A skateboard brake pedal adapter is provided for conversion of a string pull-type hand activation method to a pedal-type foot activation method for a skateboard with a pull-type brake. The pedal adapter comprises a lever pivotally connected to a fulcrum pedestal with a foot pedal at the lever front, a fulcrum interface at the lever center and a tether attachment point at the lever rear. The fulcrum interface connects the lever to the fulcrum pedestal by way of a spring-loaded resilient linkage that returns the lever to its deactivated at-rest position.
