A braking assembly for a vehicle is provided and can include a braking element having an arcuate body. The braking element can include a first lobe extending from the arcuate body and having a first braking surface configured to engage a tread of a wheel, and a first non-braking surface portion adjacent the first lobe configured to not engage the tread of the wheel. The braking element can also include a second lobe extending from the arcuate body that may be spaced and offset from the first lobe, the second lobe having a second braking surface configured to engage the tread of the wheel, and a second non-braking surface portion adjacent the second lobe and diagonal to the first non-braking surface portion, the second non-braking surface portion configured to not engage the tread of the wheel.

For stopping a zip line trolley, a zip line braking system includes an impact device, a non-zip liner parallel cable, a freewheeling pulley, a tether, and at least one spring. The impact device rides on a zip line cable, wherein the impact device is positioned down the zip line cable from a zip line trolley that rides on the zip line cable. The impact device does not ride on the non-zip liner parallel cable. The tether connects the impact device to a first freewheeling pulley. The impact device applies a force to the first freewheeling pulley via the tether in response to a zip line trolley contacting the freewheeling pulley. The at least one spring is disposed on the non-zip liner parallel cable and slows the freewheeling pulley, wherein the freewheeling pulley decelerates the impact device and the zip line trolley via the tether to a stop.
