Gti-r Brakes Cut Out When Car Spins Out - Help?

[Dumb01]

Hi all

I have a GTI-R that I have converted to RWD by welding up the centre diff and pulling out the front diff and shafts.

When i have managed to over cook it sticking the back end out then started spinning out, iv'e jump on the brakes, the brake pedal has gone solid and i seem to have little to no brakes at all. This has happen 4 times now and i'm a bit over it.

The car has ABS and it doesn't seem to matter if the clutch is in/ out. It seems to be more than just losing vacuum to the master cilinder but i could be wrong. Brakes and hand brake work well at all other times..

Any ideas why this is happening? if its linked to the ABS system?

Cheers.

ive had a similar problem with my old GTiR. i found that i was missing a nut on a control arm that came directly off the thottle body's. hard to explain. so heres a pic i edited of my old pulsar. hope it helps. got the problem spot circled in blue... if you look real close at it you can actually see a shiny new bolt there!

Pull the ABS fuse and retest... ABS doesn't like when you go forwards then sideways then backwards.. I have tried to hit the brakes after doing a burnout in many abs cars. Abs goes mental, pedal goes hard, car takes ages to stop.

Thanks for the input. I will check both of those ideas out.

Sounds like an in car switch hooked up to a relay to turn the ABS on and off may be the ideal solution if it works.

hahaha sounds like a BEAST! any pics/vids?

Hooked the relay and switch up tonight so will see soon enough if it has worked.

Gtir doesnt look anything flash, attached a pic. Found an oldy but a goodie of my old evo stuck in the sand dunes too. Fun times.

Will get around to making a GTIR video at some point soon hopefully. Need a bit of practice first so i dont look like a rookie.
