Front Wheel FROZE

OK So I jacked the bike up today to put air in the flat front tire. I went to spin the wheel and well it didnt move. I tried a little force and still nothing. Some WD-40 on the axle and push real hard sound ok?

As for the air I have to go get a real compressor. This thing I have is useless lol. Locked up without putting a drop of air in it. Could be a stuck needle I guess.
 
Check the caliper

Check the caliper

It's possible that the caliper is seized, depending on how long the bike sat. I had dried brake fluid after my GS 750 sat for several years undercover, indoors. The rebuild of the calipers and master cylinders was not all that difficult, and will probably save you a lot of trouble in the long run.
 
Yea it looks like the issue. I lubed em up and it spins tough. I will pull em and check into rebuild kits or just replacing them. Thanks!
 
Wheel bearings hardly ever just sieze... you'd hear them going long before they lock up

I just got it the other day so its history is a mystery ;) But it does look like the calipers. I will try and clean them up and bleed some fresh fluid through them. Or else its off the come.
 
If you're sure it's the calipers, I recommend a rebuild, which is just a flat O ring. If the brakes have been sitting, the piston (s) may be pitted. Replace them if they are.

Fresh fluid is rarely enough to get them moving. Remember, they're over 20 years old.

Pretty easy job really. Use compressed air to get the piston out. Clean and assemble with new seal/piston. Done,
 
If it's like the 1100's, there 2 pins that the calipers slide on. they can be removed, cleaned up, & relubed very easily. They are the 2 bolts, that aren't the mounting bolts, on the outside of the caliper, I think 13mm. Mine started not releasing, on the way home one day, when I got them out, they were gunked up with corrosion & gunked up old grease. Cleaned & greased, and everything has been fine ever since.
 
Pop the bleeder open, then try pushing the piston back using a screwdriver or a small prybar. Pistons might just be stuck with surface rust. I've see it to many time when I've bought bikes that have sat for a few years. I flush my brake systems every 2 years with fresh fluid to prevent the dreaded stuck caliper syndrome

Hmm. How exactly do I use a pry bar or screwdriver and not damage my rotors? Take the calipers off?

Yep! And find a decent sized c-clamp. The front calipers only compress from one side, so compressing the piston should't be too difficult with the pads removed. Mind you, I've not done this on the bike yet, but the calipers aren't much different than a car. And while you're at it, you might as well change the pads.

Oh I am sure it needs pads ;) I didnt think about the C-Clamp. Wonder if I still have one some place :) Thanks!
 
I took em off to get a new tire on the bike. They were the culprit and are completely hosed. I am gonna try and take em apart tomorrow. Joy.
 
Blow compressed air into the banjo fitting (inlet port). Be sure to put a rag on the piston first though or it will shoot out and hit the floor. After you get it out, clean all the jelly gunk off and check for pitts on the piston. Pitts = junk since they will cause the seal to leak.

Good luck.

Did the same this last week got an 1100g that had been sitting for 8 months in the weather. It wasn't so much the pistons as it was the sliding pins full of junk. rusty and horrid, just cleaned them up and lubed and away we went.
