20KingQuad16

I just bought 2 Suzuki King Quads, 400 ASi. One is a 2015 and one is a 2016. Both of them have these loud squeaks, especially a low speeds. Even when it goes away it comes back again when the brakes are applied but also I will hear it more when I turn or get the wheels at odd angles trail riding. Otherwise they sound fine. Are squeaky brakes just normal on these 4-wheelers? (They both have very low miles so I know it's not worn out pads)
