Hey guys, i need some help diagnosing my grizz. It's a 2014 700. I was hunting up north and rode into a 3' wide by 3' deep washout at 20 mph. It was dark and i didn't see it in time. I flew over the bars and ended up with sprained wrists and a mildly separated shoulder. I was lucky. My grizz was nose down in the washout idling away when i got up. I turned it off right away. We winched it out and took a look. My rox bars were pushed forward to the rack. That was from me gripping the bars, applying the brakes and getting launched. Not a noticeable scratch or bruise on the quad. Here's the symptoms. We pushed the bars back to where they were. The back brake is grabbing. The rear hand brake lever is very firm, like it's applied. The shift linkage is off a little. I had it in High and it was in low. I knew something was wrong so my buddy towed me with his 09 grizz 700. The brake was dragging and got worse to the point the rear tires were skidding. I don't know what would cause this. When i get time and my shoulder is feeling better i'm going to pull off the side panels and look at the gear linkage. I don't see any bends in anything other than my winch mounting plate might be a little off. I am super lucky and didn't give a shit about my quad after i got up. Lesson, don't ride fast in the dark. Stupid me, i knew better. If you guys could point me where to look to check over the brakes and shift linkage problems, that would be great.

Glad that you are ok, if you pushed the handle bars to the rack that is some force, amazing how much of a jar, 20mph to zero is. In my youth, running in my vow mud buggie, I hit a cedar stump that was growing out of a cutoff cedar stump, thought that, I could just run over it, about 20 mph to zero, bent steering wheel all the way to dash, knuckles stuck to dashboard until I pried the steering wheel back out, and the front seats let out of the rails. That stuff hurts more the older you get.

Look for a pinched cable, also look at the foot control, might have a stick in it, not sure if you can stick a brake caliper with enough jar from front steering being pushed that far forward. Start looking at handle bars first and work way down.

I would suspect the frame may be bent, as you said the winch is off.
Look for crinkled paint on the frame and check the wheel alignment.
Do the plastics look straight or can you see buckled stress waves?

Wow, glad that's all that happened to you. Good luck!

Hi ross! wow! what a learning experience, huh? Ouch!

Please send pics and let us know what you find.....


Just as a thought, Check the Banjo bolt (the 12mm bolt on the rubber hose) on the rear master cylinder, if its bent, it will keep the fluid from returning to the master cylinder and keep the rear brakes applied.

Yes it was an experience. I'll look at the banjo bolt later today. I'm going to take off all of the side shrouds and inspect the frame once my buddy gets his quad out of my garage. I'll update the post once I dig into it. With regards to the rear brakes, the foot brake works as it should, but the left lever is stiff and won't pull in. There is no click sound when you apply pressure on the rear hand brake.

the foot brake pulls a cable that activates the rear master cylinder (on the left handle bar) ,,press the foot pedal and look at the metal loop under the master cylinder, bent or broken or twisted..we'll wait for your reply..

regards,
the collective

I got to look at my quad a little more today. It's still filthy dirty, but i was able to examine the front end and compare it to my friends 09 700 Grizzly. My bumper took the hit, my winch is the same as his. I have a 1/4" ding in the left hand side of the cross bar of the bumper. When looking at the front end from the top, the left side is in about a 1/4" compared to the right. When looking directly from the front, the right hand side of the cross bar is raised a bit compared to the left. I'm hoping it's just my bumper that's bent. I can't see any damage on my frame from the sides of the quad behind the front wheels. The wheels seem to be true and not off.

I looked at my rear brake again tonight and it's not frozen. I'm able to push the quad with a little resistance. The brake lever goes in and the foot brake works as it should. It just seems very stiff, like there's a lot of pressure to activate the rear brake. My friend's 09 is very soft and mushy. I'm not sure if mine is supposed to be like that. It doesn't click when you pull the lever like the front brake, but i can't remember if it did before.

Tomorrow i'll pressure wash it when i get time. I'll reference my factory service manual and pull the front plastic off and take a look at the bumper and frame. I'll also adjust the shift linkage. It's a little out. I can't see why this would go out of adjustment with the impact. I had an issue with shifting last hunting season but i attributed that to ice build up because it went away this year. Thanks for all you suggestions and help guys. I'll get this thing fixed. It's still looking new and is in great shape other than my current issues. I baby this thing and it has low hours and miles. I'll update as i dig into it.

Check that the rubber brake line hose isn't kinked or pressing against the handlebar after they dropped forward in the crash, the lever section might have slid around pressing the hose against the h/bar, if not follow the hose there's a pinch somewhere, you can test this by wrapping tape around long nose pliers & squeezing a working brake line & it will tighten the lever, same as yours. If the line has a pinch the brake piston won't retract properly, the pads rub on the disc, the pads heat up, this heats up the piston which heats up the fluid which expands under heat & pushes the piston out & the pads against the disc, when cool you can push the calipers against the disc to get the pads off the disc & free the wheel, this can get you out of trouble BUT no front or rear brake.

Does the brake lever flop loosely up to a certain point and then it's very firm?
Check under the brake lever. There is a hoop-shaped piece of metal in which a round piece of metal slides. If that got bent, the slider might be getting stuck.
Also check to see if maybe it's not bent but got jammed up against something else with the same result.

Thanks for all the help and suggestions guys. I got to washing my quad yesterday and had a sinking feeling when i examined my clean grizz. My frame is bent just behind the rear attachment point for the front a-arm. I noticed the paint cracking. I then looked at both of my front wheels and the distance from the back side of the front tire and front fender is off by over an inch. This is why my shift linkage is off a little. My rear brake still feels super firm, but it's released enough that i can spin the tire while the quad is jacked off the ground. The bend doesn't look too bad, but i'm not sure if i can get it back to where it was before. I'm going to have the honda dealer mechanics look at it to tell me if it can be repaired. I know what you're thinking, why honda. My wife used to work at the dealer and they are doing it cheap. I don't have insurance and can't see paying the yamaha dealer for a new frame and 30 hours of labor to get it done. Ive yet to price out a frame. I'm in Canada so i know it will be up there. I guess i just have to be happy that I'm ok.

That really sucks man, sorry to hear it.
When you get it fixed, or get a new ride, do look into insurance. It's cheap, and accidents do happen.

Yep. As much as it sucks, it's just bent metal. That's way better than a bent you.
