I have a 2007 grizzly 700 and when I first got it the front brakes would lock up like abs. When I grab them normal they lock up . The front brakes would never lock up when I pull the lever slow it does not slow the quad down easy. Right now I have 2000 miles on it and all I use are the back brakes. Is this normal for grizzly 700s?

 

Check front pads for dirt and wear. Caliper piston may be seized as well.

 

I will check it. It has done this since I first got the grizz

 

This is deff not normal and a problem and one I have never herd of on a Grizz. My guess is you have a front master cylinder malfunctioning. You can check with the guys at http://www.grizzlycentral.com/ if you want a second opinion. Good luck let us know what you find.
