Default Handbrake turns?? simple question

well, used to do that in my FWD car, and was fun..
and i tried it yesterday, with my awd scoob..

all went well, but abt 100 m away, i got to a roundabout, and i felt the car losing grip. ... well, that didnt seem to b normal cuz i used to do roundabouts at the same speed (not too fast), and just after that, i was taking an exit off the roundabout to join the M23, then i felt it slipping on the road as well,
but everything was fine on the M,way...

well, does that cause damage to the car?? or anything???
should this NOT be done on AWD cars??
any idea y i felt like my car is slipping on the roundabout???

---- for some - am not a mad racer boy, bt i do feel some extra adrenaline in my veins sometimes, when am alone on the road....

thanks.....

i used to be handbrake happy in my fiesta st which was fun at times

then got the scoob and thought ooooooooo drift for real now, so i pulled the handbrake the get the initial drift started, well after a few pulls my cable had stretched pretty badly and now my handbrake is pretty crap and really need to replace the cables.

but with most power hitting ur back wheels its just gonna wear ur brake shoes more than anything

i wouldn't of thought so but driving a car with handbrake up isn't good for any car so pulling a handbrake on a car that sends most power to the rear wheeels aint gonna do it good imo.

but hey i'm guilty of doing it in the past

Dont do it, scoobs unless DCCD are perm 4 wd, pulling handbrake up puts strain on expensive drive system, same goes for towing the car, cant lift front and leave rears rolling on road as it will mash your system.

the wrc cars have a different set up i belive, so when the hand brake is pulled it just lockes the rears up, and not the hole awd system.

never a good thing to do in a road car

Besides rally cars being set-up to only lock the rear wheels their handbrake systems are also converted to hydrolic systems. As mentioned earlier above the conventional cable system just is not designed to take this kind of "abuse" ;-)

Also take note of how the WRC drivers use the handbrake next time you watch some in car footage. They simply flick it on and immediately off typically as they simply use it to induce oversteer. Once oversteer is induced, handbrake comes off and car is steered through the corner using throttle, counter steering and a bit of footbrake dabbing if necessary.

You CAN use your regular handbrake in your road car in the same manner i.e. just to help induce oversteer but in an AWD NEVER drive with the handbrake engaged like you could with a FWD. Power is sent to all four wheels all the time and if you suddenly lock the rear whilst still sending it power, imagine what strain your are putting on your drive train! NOT GOOD! If you do feel the need to use it to induce oversteer, the trick is to engage the clutch first, then handbrake as you turn, once the car is sliding sideways going into oversteer, release the handbrake, let go of the clutch and get reddy to counter steer and throttle powerslide it.

Hope this helps.
Cheers

Hence the use of the clutch BEFORE you engage handbrake trick
Click on my "View My Scooby" and you'll see a pic of me doing exactly this on a skidpan - note frontwheels full counter locked
But agreed, not recommended in general, easier and more forgiving on car in the wet and probably more forgiving on DCCD cars. Besides, we got Scandanavian Flick - who needs handbrake turns! LOL!

When you see how puny looking the handbrake shoes and general set up of the shoe mechanism is, i'm surprised they don't fold in half if you pull it on with any force, never mind while on the move.

by law the hand brake only req to be 16% of the tolal brake eff/ because you have a diagonal split or front and rear split braking system .it only a parking brake . geo

i know this is an old post but how much would it roughly cost to convert your handbrake on non dccd to wrc style? hydrolic that allows for this? or would it be cheaper going dccd
