Hi,  I am new on this issue,  I just got the rep for an UTV for GUATEMALA,  I was trying out today the UTV 700,  but it has a problem on the brake system,  when you come to a complete stop it has a grinding noise on the back, and also the brake pedal is spongy and goes all the way down,  Have you got a similar problem?, are you familiar with this kind of UTV´s?,
