Just bought a used 2014 Grizzly 350 and I absolutely love the engine braking. I didn’t think it was a big deal when I heard about it but it is really a nice safety feature for going down steep grades. I normally have a death grip on the brakes going down the hills and now I hardly ever use them, the brakes should last a really long time. My question is, are there pads or discs or something on the engine that functions the braking feature that needs to be checked or periodically replaced?
