Oh my goodness, there is no worse feeling than sinking a putt, celebrating with jubilation among your friends, only to turn around and see your Yamaha rolling down the cart bath backward towards the drink girl. We don't know about you, but we would do anything to prevent that from happening. That being said, the first time you have to try more than once to engage your parking stop, it's time to replace the Yamaha Hill Brake Spring with an aftermarket clone of the OEM from us. The absolute last thing you want is to be the club's laughing stock because you hospitalized a poor waitress and sank your cart into a water trap without even being behind the wheel.This coil is more commonly referred to as the golf cart brake pedal return spring. This one works for a wide range of years and models fitting Yamaha G1-G22 gas or electric models. Grab that parts and service manual and match it up; this should replace OEM Number 90508-405A9.
