I have a brake cylinder that is stuck on both sides of the front brakes. Does anyone know if I can rebuild this? The parts have been discontinued and I am having a hard time finding them.

Thats going to be the problem most likely. The best you can probably hope for is to find a usable part on ebay. I just sold the right side set for an 86 that I had originally bought on ebay but never used....but, an 86 wouldn't fit your machine. Just keep an eye out on ebay or search around on craigslist or even watch here. There is someone parting out one of those machines now if I recall.

That would be great if anyone is "parting" the ATV. Please let me know. THANKS

Just keep an eye out in the 'parts' forum and one might pop up. There's an 86 there now, but like I said it probably won't be the same part... the 86 is different than the 87-89 models.

I agree with Pain. Keep an eye on Ebay and the "parts for sale" forum.

Hey guys.
I was able to apply a little heat, some WD40 and 2 flat head screwdrivers and pry the piston out. A little bit of light sanding and cleaning and it works good as new. (one of then the rubber was cracked but it was only $4.00 for a new seal)

FYI for those that have the same problem.

first off..never ever pry those out !..if you score the piston bore..your up the creak without a paddle and leaking boat. from now on..here's what i do..and it works like a champ..get a grease fitting the same size as the brake line..get a grease gun..screw the grease fitting into the brake cylinder..just pump grease into the brake cylinder..and that rusty old piston will pop right out. works very easy and fast !

The amount this thing was stuck it would have shot off like a gun. I thought this thing was toast and was under the impression it could not be fixed. It worked so far so I'm happy, but great idea, I will try that for sure if I ever have the problem again.


Thanks

nah..the grease would of kept it from shooting out like a cannon ball..lol..i've used that trick alot..i just restored my ' 89 trx350 foreman..and i had to use this same trick to unfreeze the brake cylinder's..even if they have been froze for along time..the grease gun trick will pop them out real easy...i've been working on 3 and 4 wheelers and motor cycles for along time..and if i find a easier way to do something..i stick with it..lol..
