I went thru the same thing, including sending them back to saitek for repair. After 2-3 months, same thing with forward position lock up. I tossed 'em in the trash and replaced with CH peds. Five years later, I've yet to have an issue.Anything Saitek craps out sooner or later.
The only other suggestion...during the period my peds would lock fwd I slam the back pedal forward with considerable force. Sometimes it would solve the problem. Even when it did, sooner or later they'd lock again.Maybe buy a cheapo twisty until you can replace the peds???
Mine still work great,,, I've had the wood underneath them for 4 1/2 years now and never once had them back apart,They work as good as the day I fixed them!
Quite expensive but I have heard great things about thesehttp://mfg.simundza.com/mfgcrosswind.php(Image removed from quote.)
Lol, I have a pair of Saitek pedals that only work when attached to a keyboard USB in. Dont ask me why, Ive tried every possible fix and combination. Its the same even with different keyboards. Weird.
