This has literally been KILLING me. I made an account on these forums just to get help, so please do! My father passed down the preddy to me because he's "too old" for it now, before he stopped riding it, he wrecked it. The master cylinder is my only issue. It was missing a clamp, and the parking brake, which i ordered both and fixed so it's back on the handlebar, BUT the last spring and the little piston before the rubber tip are gone. I have searched all over to find the outer-most piston and spring for days, the only way i can find to get it is if i were to order an entirely new master-cylinder just for those two parts. If ANYONE knows where I can find these two parts and save me $100 in Oklahoma you'll help a new preddy owner sleep avery at night. Thank you very much for reading.
