I have an '07 Yamaha Grizzly 350 4WD I bought new. The front brakes are locking up and when I squeeze the brake lever, it absolutely will not budge, no play, no spongeyness or whatever. I completely rebuilt the master cylinder and brake calipers with new seals. There are three flexible hoses and I replaced them too. All parts were Yamaha OEM. I flushed the fluid and bled the air out twice. It's still doing it. In order for me to ride the thing, I have to bleed the pressure off of it. After a while, the pressure will build back up.
