Jittery Brakes

I’m using CH rudder pedals and I’ve seen the other posts regarding weak brakes but that’s not my problem. When I go to sensitivity settings I see the dot for left and right brake at the bottom left corner of the graphs. However, when I “begin” to touch either brake, the dot suddenly jumps to the center of the graph rather than following the line linearly. I barely touch the brake and it does this but as I continue to apply braking force the dot then moves smoothly from the center of the graph to the upper right. None of the adjustments of dead zone or sensitivity changes this action. When in an aircraft like the Spitfire, the result of just touching either brake pedal without actually moving the pedal results in the parking brake lever moving or braking action as seen in the air gauge. Any ideas what’s going on here? Other than this, the brake action is strong but its annoying to be flying and hearing the air system hissing and the parking brake moving every time you make a rudder movement.

Update: When in the controls menu and viewing the white line (left right slider) for brakes, it appears its supposed to start in the center and move to the right as you apply force to the brake pedal. But if I completely remove my foot from the pedal, instead of the line staying at the center it jumps off to the left so no white line is visible at all. If I touch the pedal, it jumps to the center and begins moving right. How do I get the line to stay at center without applying slight pressure to the pedals? Seems like a calibration is needed but I don’t see any way to do this.

Are you sure it’s suppose to be starting at the center? The X and Y Brake axis from the CH Pedal should start from empty. So a fully release pedal means it’s fully release the brake.

Only the Z Rudder Axis is meant to stay at 50% center on release, but this is meant for Rudder Axis that applies Left turn when the pressure is between 0-49%, and Right Turn when the pressure is between 51%-100%. And 50% is completely neutral.

The Brake is suppose to come from X and Y Axis, which starts at 0% empty bar for full release, and proportionally pressed towards 100% for full brake pressure.

You have to also set your sensitivity curve accordingly. Ideally, X and Y Brake axis should be fully linear at 0% in everything except for the reactivity at 100%.

A little off topic: did we ever found out what “reactivity” actually does?

The CH pedals are not supposed to start in the centre. Use the windows USB controllers option to recalibrate them.

If that doesn’t work reset them (same menu).

Reactivity is about the delay between the input signal and the sim actually applying that input. At 100%, your input is immediately recieved and immediately applied to the controls. On lower reactivity, it still receives the input in real time, but it has some delay before that input is actually being applied to the aircraft.

@ Neo4316, even in the Windows Game Controller calibration screen after calibrating it does the same thing as in the sim. The X is in the upper left and if I touch a brake pedal it jumps a quarter way towards the right and then proceeds smoothly the rest of the way to the right as I depress the pedal. I wonder if I have a bad pot but its strange “both” left and right brakes do exactly the same thing. Resetting them in the sim sensitivity window didn’t do anything either.

I had this same problem with my ch pedals as well. I had to always keep firm pressure at the bottom of the pedal to prevent the parking brake releasing all the time. In order to fix the problem, I wound up recalibrating the pedals without fully letting off the “brake” axis, but acting like I did. In other words, I made the pc unaware of this extra travel, so once outside the calibrated range, the pc wouldn’t react to the pedals. I’m sure this is confusing, lemme know if you understand.

@FedEx2150, That absolutely worked! A fake offset to get beyond the “noise”. Thank you very much!!!
