gpl braking

Is there any way to stop the wheels locking under braking ? I always seem to lock up no matter how soft I am with the braking.

What controller are you using? I would check your brake calibration or pot. You should definitely be able to brake without locking. Nafi >Is there any way to stop the wheels locking >under braking ? I always seem to lock up no >matter how soft I am with the braking.

I've had a lot of probs with my CH Pro Pedals locking, at least with the trainer cars. The prob as I see it with the CH's is the very limited travel range. I have to be very precise otherwise it goes into lockup. My solution? I've dialed back the brake balance to about 52% forward. Which may be detrimental in reducing overall braking capability, but it gets the job done.

If when you first get into the brakes you go more than ~25% throw, you will often lock. Go deeper from there once weight is transfered forward.

? done. Doesn't this just lockup the backs first?

Like everything else in GPL, smoothness is the key! However, on a real car the brake "pushes back" on your foot so that you can feel how hard you're braking by the force you're applying to the pedal. On current PC controls, brake effort is strictly a matter of how far down the pedal is. This can make it extra difficult to be consistent, so even more caution is required.

You might try this. When calibrating your pedals, after setting full travel for them, hold down on the brake pedal slightly before clicking on "ok" to save the settings. There's a reading above the bar that goes from 0.0 to 1.0 as you move the pedal. Hold the brake down to about .2 - .3 while you click "ok". This will keep the brake from being actuated at first touch, and may help you compensate for the long pedal travel in some controllers. Experiment till you find a setting you like. This assumes you have your pedals on separate axes, but you can probably do the same without. Steve B.

52% ? That's a very moderate front brake bias, IMO. I usually start with 65% and reduce it until the rear of the car starts overtaking when braking. As for locking up the brakes: you have to un-learn braking techniques from ICR2 or GP2. In those ground effect cars, you can slam on the brakes at high speed, and the downforce will keep the wheels from locking until you're very slow. A wingless car will lock its brakes at any speed, high or low. If you brake hard at top speed or immediately after accelerating, there will be even less weight on the front wheels, so they'll lock even earlier. You have to brake a little to transfer weight to the front wheels, then brake harder until your front wheels are about to lock. In theory, that is. :) I can't do it consistently myself, but I'm getting better. -- Wolfgang Preiss \ E-mail copies of replies to this posting are welcome.

It should. But I do know I have better control, ie less propensity to lock anywhere. But admittedly, it probably is not the best way to do it. As witnessed by my lap times (1:54's at Monza with Trainer), I have to work on my technique.
