I am new to this forum and have found a lot of useful information. I'm hoping someone has seen my problem. I'm somewhat handy as I've had several different ATVs and motorcycles.

My father-in-law has let me borrow his Foreman until his health recovers. While I have it, I was wanting to bring it back up to speed as it hasn't been used but maybe once a month for the last year. The front brakes work fine. However the back brakes have problems. They are stuck.

I took the rear brakes down to the brake shoes and found that he has let water get inside the drum and has caused this whole assembly to rust up. I managed to get the brake shoes off where I can really see what was going on. I guess you would call it the "actuator" that moves the brake shoes in and out is frozen. I squirted as much WD-40 that the EPA allows and tried to rotate it by the persuasion of a nice rubber hammer, but it moved very little. Best I can tell is that it is rusted along the shaft between the inside and outside of the housing. I tried for several hours of hit, squirt, hit, squirt.....hoping it would finally move freely, but it never did.

Has anyone ran into this problem? I'm wondering if that shaft is removeable or if it is pressed in or even replaceable???

Any advice would be greatly appreciated.

Thanks,
JeffL

 

One suggestion as an auto mechanic and shop owner, wd40 isnt worth its weight in anything anymore..another product that is great on siezed bolts is called PB Blaster. Comes in a spray can the same way and is so so much better. If it doesnt work, you are probably gonna have to put a little heat on it with a torch. Dont overheat though, the actutator could be a soft metal.. good luck.
