I have the USB CH Pro Pedals. I have noticed that the left brake pedal will not release the differential brake unless I push down on the heel of the pedal. In other words the red "differential brake" message will not disappear! I have a tough time taxiing. I have tried changing sensitivity and recalibration, but that does not work. It seems that this might be a hardware issue. Has anyone experienced this problem and is this something I should try to fix myself or send it to CH products. I am NOT under warranty. I might be willing to open the case to see what the problem is. Should I ask CH products what the problem might be?Thanks for any help!Airbus

Hi there,I had the same issues and the only way I managed to cure the sticky brake situation was to edit the brake axis null zone within FSUIPC's joystick settings.I think you'd need a registered version though...Cheers, Alex

Hi,You may also download CH Control Manager and calibrate and define null zones for your CH pedals. No need for a licensed FSUIPC.Have a look on http://www.chproducts.com/retail/tech_support.htmlUlf B

Hi Airbus, The good news is that there is nothing wrong with your CH hardware, nor with the CH software if you are using that. Your toebrake axis are installed backwards in FS. When your feet are off the brakes the game is reading maximum value 255 instead of minimum 0, (or is it the other way around I forget), As for sensitivity and recalibration that is not the issue. I had the exact issue which you describe. So have lots of others here. A single line edited into FS9's main config file solved it for me. It's a flightsimulator file, not a CH file, and FS puts it into the Windows Users folders area, not into the FS9 main folder. Unfortuneately I don't have FS9 installed right now, but I recall I changed a value of 64 to -64 in two 'toebrake' lines in the FS9 main config file (whatever that was called), and then set the file attribute to 'read only' to keep FS from overwriting my edit.Probably you can accomplish the same thing by ticking a reverse axis box in FS9, if there is one. Or tick reverse in CH control manager applet, or in a purchased copy of FSUIPC, or do a search on forum messages to find where someone lists the exact edits in the FS9 main config file. I recall ticking the boxes didn't help me, but editing the sim's config file did work perfectly and permanently cured the issue.

Everyone,Thanks for all your helpful suggestions. Fortunately I have a registered version of FSUIPC so I was able to mess with the brakes setting. By holding the brake pedal down a little I was able to create a slight offset which allowed a complete brake release and no differential brake message when the pedal was in a rest position. I am still testing it, but so far it has worked.Thanks again!Airbus

Hi, assuming you installed,calibrated, etc,and you get the brake light on,like I do often,I suggest you switch the usb left,right. Re calibrate.After that, shut down and restart. This works for me GOOD LUCK!! VIN
