There’s only one rear mechanical brake on the rear righthand side. Only true way to tell would be to pull the rear drum off, put the tire back on and see if it moves. Or pull the drum off, jack up the atv, and then see if the rear tires will spin. If it doesn’t then it’s mostly likely something seized within the crankcase. Which could be anything really.

 

I should be able to tell just by pulling the brake and or stepping on the peddle right? If it just bottoms out.. then its the brake?

 

Pulling the brakes or just removing the rear drum should help determine if it’s simply the rear brakes or if it’s in the in the rear end. Had the right front brake seize on my 300. Only way it would move is if I pulled the front drum off. The minute I put the drum back on it wouldn’t budge. That’s how I figured out it was my front brakes causing the issue. Turns out one of my wheel cylinder ingested water, froze over the winter, then seized in the fully applied position.

 

How bad is it to replace the rear end? Not opposed to the work.. but is it worth it? Just trying to get a machine that works.

 

Never replaced one, so couldn’t really tell you. Though depending on what might be broken is another story. Then you’d need to figure out if there’s any part availability and how much it would end up costing you in the end.

 

Yeah.. that is an issue. Thanks bud!
