Formula III brake problem

I've been having problems with my brake locking up. The first time it happened, I checked the fluid level in the reservoir and it was low. I filled the reservoir and drove the sled all of 2 miles and it happened again. I let the sled sit overnight and drove away no problem. Made it about a mile and a half and again it locked up. Is there a way to adjust this brake? It seams as though even when it's in working order, it is very sensitive. Any ideas? Thanks!

I don't know, but I swear all of them older ski doo brakes are problematic. My friends 95 Formula Z last year started on fire due to the brake locking up and sparking and igniting. Now, my other friends 1995 Formula Z is doing the same thing. Give the rotor a good check over and make sure nothing is leaking. I think there is a way to bleed air out of it also.

Formula III brake problem

Sorry to sound stupid but i'm not very mechanical. How would I go about bleeding and flushing the brake line? Thanks again!

hook a piece of clear nose to the bleeder on caliper.
then remove cap of mastercylinder, loosen bleeder.
then pump brakes slowly, make sure that master
doesnt run low while pumping. pump till clean
fluid gets into clear line. tighten bleeder and
remove hose, fill master to proper level.
make sure not to get any brake fluid on ANYTHING.
will do damage to plastics real quick.

renagade is spot on! its fluid. everyone should follow his bleeding steps every 2000mi cuz not only can they lock they can also overheat w old fluid and fail. seen it. not good! brake fluid is cheap

My 96 Formula SL had this same issue, bled brake and it worked for awhile but repeated quite often. Someone else commented on a small pinhole inside the master cylinder he needed to use a pin to unblock and then bled system again and it worked great....

yes it is that small pinhole people are mentioning, i had the same problem on my 96 formula z 583, what you need to do is take the master cylinder cover off and soak up all the oil in the top so that its empty, there should be a very small hole right beside the main one that is clogged up, you need to take a small sewing needle or something similar (yes its that small) and clear it out. once you have the hole cleaned out just bleed the brakes (you can find good videos on youtube) and you should be all good to go, this is what i did and its been working great since

Thanks for your help. I bleed the system and my sled worked great over the weekend. Again Thanks!

I've had the exact same symptoms and was have noticed the same exact small clogged hole. I actually ended up taking the master cylinder out of the rubber boot (attached to the break handle). The only thing I didn't know how the seal on the end of the plunger can fit back through the boot. Maybe I shouldn't have taken it apart, but I was really tying to clean everything out.
