Yesterday I was powering up a trail when my rears dug in (no big deal usually) then as I started to slide backwards I applied both breaks generously to control the roll when I realized my rear brake pedal went all the way down and felt there was no rear brake, so as you can imagine I'm facing up a hill with nothing but my front brake dragging (here we go!!) I kept in the trail for a bit but it just picked up too much spped in the drag-skid, finally it kicked sideways and I bailed just too watch the Rappy do a somersault and land right in front of me. Luckily the only damage was a bent clutch lever and a few scrapes and scratches on me and the bike. Now that I'm all good I begin playing with the rear brake and figured out that there is plenty of fluid in the system from the MC to the Caliper. When I push down on the brake lever the plunger goes up into the MC but nothing happens. Any ideas on how to remedy this? Thanks.

 

The firts thing I would do is crack the bleeder valve on the rear caliper, then depress the brake lever, if any fluid comes out of the bleeder valve, the caliper is probably frozen. If no fluid, the master cylinder for the rear will need to be rebuilt or replaced.

 

I checked it, fluid comes out when the valve is cracked and the peddle depressed. So I guess the caliper is bad?

 

It's the vibration that causes the rear brake to fail. Mine went out at the dunes a little scary but no serious damage. Take it into the dealer they actually have a recall on it and they will take care of it free of charge.....Good Luck

 

to avoid all of that keep on the throttle while going up the hill if your momentum stops let the rear tires dig in, then get off the quad hold the front brake and pull the front around facing down hill then get on and ride down.

 

I know this doesn't help after the fact and sorry to hear about your mishap...

I had a similar instance happen but i didn't have the ability to get off the quad due to the steepness of the hill and the off-camberness. So I had a friend hold the front down (he was facing the front of the quad) while I slowly skidded down backwards with just my front brakes. I have taught myself to NEVER touch the rear brakes when stuck up a hill just out of safety incase i accidently loose the front brakes and the rear brakes grab and flip me. Now when i sit at the bottom of a hill I always make the educated decision of which way i will be coming down the hill. I've bailed the quad into the trees on the side of a hill once which actually saved both me and the quad.

I've only been riding for a little over a year so take that for what it's worth.

I'm glad to hear you bailed, I know a few guys that try and save their quad before themselves and that just makes no sense. Go ahead and cry while your quad gets smashed to pieces. It's better than a loved one crying over your split skull [img]i/expressions/face-icon-small-smile.gif[/img]
