I'll start off by showing how to change the rear brake pads (Mounted on Driveshaft)

2005 Grizzly 660
First of all you will need the following items...
-5mm Allen Wrench
-Flat Head Screwdriver

You will need to jack the ATV up and remove the rear left wheel/tire. I haven't attempted this with the tire on, and really don't recommend it.

Look towards the back of the driveshaft and you will see the brake assembly.

--------

You will need to try to pry the brakes back to compress the pistons... You can loosen the bleeders and let them squirt out when you do this... They need to go back as far as possible... (This is where that flathead screwdriver comes in) After compressed all the way make sure to tighten the bleeders and put the caps back on.

---------

After compressing the pistons you will need that 5mm Allen wrench. I will go ahead and tell you, your going to want the shortest allen wrench you can find, this part is the most time consuming. Kind of a pain in the butt.

First of all you will remove a small "Cap" Its a short allen screw, after its removed you can remove the larger pin that goes through the back of the brake pad.

After that bolt is removed you can take out the old brake pads and insert the new ones...

Once they are in place you pretty much just put every thing back together... Pump on the brakes and they should tighten up... If for some reason they do not... You will need to bleed them... I have never had to bleed them.

Thanks for reading, and apologies for the crappy drawings on the images

Thanks, normally when I do something like this I try to document it so it's easier next time... I may be posting another helpful thread in a few days.. I'm changing my rear wheel bearings right now so I'll probably do a write up on that... And found a place to get the bearings for 13 dollars... I'll pick them up on Wednesday and if they are the right ones I'll post more information for everyone then.

There are a couple of things you overlooked, but Thank you and Good job on the write up!

You need to mention that the caliper should be cleaned with Brake Cleaner before reassembly to
prevent any excess brake fluid for getting onto the new pads.
Also - if you remove the cap on the resevoir you can compress the pucks w/o opening the bleeders.
this will prevent air from getting into the caliper and having to bleed the line after reassembly.

I didn't thnk about that... I didnt get break fluid anywhere so that wasn't really an issue.. The liquid in the photos is carb cleaner I was trying to clean everything off a little bit so everyone could see what was what!

and thanks for the info on the brake compression.
