Brake pressure advice?
« on: August 13, 2008, 02:17:28 pm »
Hey all,

I've just jumped back into GTL with almost no recollection of how to drive, so that's prolly my first problem. Last night I was just trying to come to grips with the cars and how to drive them (in a general sense) and unlike a sane person, I was poking around with all the different cars, instead of sticking to one and learning that one.

I noticed something interesting when I was playing with the TVR at Zolder. I'd drive a decent (for me) lap, and then the very next lap, was all over the place. I went to the outside cam view, and noticed that I was locking the tires a ridiculous amount, and was subsequently wearing out the tires in a lap! (as in, if the sign said "200" I'd hit the brakes and there'd be a line almost as long)

I improved things by fussing with different settings ( don't remember which ones exactly, was 3am, was sleepy).

Main thing I want to know after that long story is, how hard do you guys hit the brake pedal?

I've always been used to using full travel, setting up to lock just as I hit bottom in ideal conditions, but in real life, some cars grab hard high, and some low. You can tell by seat-of-pants sensations in a real car when you're coming to the limit.

Mebbe I just need louder speakers to hear my tires and a robotic arm to smack me when I lock them?   :think:

I drive with all the finesse of a builders mate on ice, so i never drive with full brake pressure, some times as low as 86% but another thing to try is moving the balance bit by bit to the rears until you can stop without the fronts locking. Im still painfully slow though  :twit:  catoe

The way i usually do it.. i make the brake balance so it helps my driving style (usually as rear as possible), then adjust the brake pressure so that i just and just manage to lock the tires.
Works for me pretty good, comfortably consistent braking almost in any car that way.

Voodoo... i'd like to see you try and lock things up on the Mustang!  (only happens sideways.. hehe when it's almost outtof control)

Personally i haven't lowered many brakepressures on cars, last weekend i shouldhave done so.. but i hadn't..
Brakebias more rearward, find out how much to the rear by slowing down for a corner from full speed for instance.. if it gets squirmy.. set em a bit more forward.. and yea.. brakepressure lower if you tend to lock up all the time. 

By lap 2 your tires and brakes are probably getting upto temperature and might be working closer to the max, if not over it a few laps later.

Thanks for the advice! I'll try mussing with the balance as soon as I get home. Darn boss doesn't think a racing wheel is "work appropriate".  thumbs up
