I got a set of brakes off a similar kid on PB, ad was with rotors, adapters & bolts, , what turned up was just brakes with a kinked hose.
Asked him and he wasn’t exactly going in the right direction, started a paypal case for partial refund and he just sent it right on through.
Just make sure you ask firt and explore every posibiity before resorting to PP claim.
Also FWIW, the difference between EVo & normal ‘tech’ levers (on the M4) is just the position of the lever pivot vs. the master cylinder (i.e. with the Evo lever blade + evo master assembly there is a little more power vs. the tech due to the position of the pivot.
There might also be a roller bearing in the lever > master interface, wheras the tech is just a lever pushing on a rod.
Ring hope or email them with pic’s and they’ll be able to shed some light on it though.
