11AGUY Posted January 20, 2012 Report Posted January 20, 2012 ok, just got my new brake pads in and thought this would be the easiest part of the winter rebuild but unfortunately Murphy's Law had to intervene.. I can't push the piston back... I hit the brake and the brake closes, but I can't push the thing back... also, the little round dust cap that makes contact with the back of the inner brake pad fell off into the ground... looks like it is siliconed or glued in place... do i have to take the entire caliper apart and clean, lube and rebuild or is there an easier fix??? all help appreciated Quote
sstaton1983 Posted January 21, 2012 Report Posted January 21, 2012 Did you push the brakes with the caliper off the rotor? if so you over extended the piston.im guessing the rubber your talking about is the dust boot behind the inboard pad.you may have the piston wedged at a angle in the bore.

I didn't touch the brake with it off... the cap I am talking about is the metal cover/cap at the end if the piston (actually thought the whole thing was one piece) Quote
Motooutcastxxx Posted January 21, 2012 Report Posted January 21, 2012 A C-clamp will push the piston back in, all though since it's apart I would replace the piston seals too, just because they're cheap. As for that little cap you're talking about I've run a few quads without them and it was fine. Quote

That mounting bracket on the caliper should slide back and forth too, if they've never been disassembled and lubed they can be a pain in the ass but it does move. I've had a few like that myself.

Motooutcastxxx Posted January 21, 2012 Report Posted January 21, 2012 If you look at both ends of the bracket where it connects to the caliper, there are rubber boots and that's where it's supposed to allow it to slide back forth. I know that's probably fairly obvious at this point, but I would say the next brake job I would just grab a caliper rebuild kit, you can find 'em for like $15 or so. Quote

Motooutcastxxx Posted January 21, 2012 Report Posted January 21, 2012 This is the one I bought, don't usually deal with DK but once in awhile, Rocky Mountain ATV/MC might have them too and they usually have better prices, I've seen them on EBay also. https://www.denniskirk.com/moose/rear-brake-caliper-rebuild-kit.p1904928.prd/1904928.sku Quote

Motooutcastxxx Posted January 21, 2012 Report Posted January 21, 2012 If it was working fine before you don't absolutely have to get a rebuild kit but at the very least just pull the bracket off and clean all of the crap out of there so it slides again and you can still have it done today. Just be careful not to rip the boots, all though I've run 'em that way too but it usually makes it even more of a bitch later. I powder coated my caliper so it all had to come apart anyway. Quote

I powder coated my caliper so it all had to come apart anyway. just got the same one you suggested (Moose Brand) on ebay for $17 shipped... upon further inspection one of the boots was shot, so with time on my side I'll pull it apart.... now the Clymer's manual suggests that you pull the brake pads off and then pump the brake until the piston pops out??? sound right??? then clean everything (states let the new rings and piston soak in brake fluid and reinstall)... thinking about picking up some caliper grease to lube everything when i re-install... it also states to disconnect the brake line. is there an easier way or any tricks... thanks for all the help this site is fantastic.....

Motooutcastxxx Posted January 21, 2012 Report Posted January 21, 2012 You could probably pump the brake until the piston pops out but I usually just disconnect the brake line from the caliper and use compressed air to pop the piston out, just don't use a whole lot of pressure and WATCH YOUR FINGERS. It's also easier to loosen all bolts that you can when it's still bolted to the machine and it can be a little messy so make sure you clean up any spilled brake fluid fairly quickly. Quote

Couldn't agree more... this site F'ing rocks!! The thing is I thought I knew a bit about quads until I joined.. then I realized I don't know shit!! Many of the guys on here just take it to a whole new level! Talking about things I've never dealt with or even thought about.... Quote
