Early ABS activation?

[achillies]

I have a 2000 Carrera it has new rotors, pads, fluid flush. When I apply the brakes hard I seem to activate the ABS very early..the pulsing starts way before the car seems to be ready for lock-up. I hope I am describing this correctly. The tires are Falken 452s with less than 4000 miles. The brakes did this before the new pads and rotors. The car stops ok but doesnt seem to have that "porsche" braking. Thanks

Brakes don't stop the car, tires do. Your tires while probably only marginally worn can not transfer the braking force applied by the brakes to the pavement thereby causing the ABS to kick in prematurely.

So maybe it is the Falkens being overwhelmed by the brakes? Better tires would solve this? Thanks

Tires could be the issue but also check the air gap for the wheel speed sensors and also the trigger wheels for any damage or dirt/stone build up in the teeth. I assume the tire pressures are correct.

NOT...!!

ABS activates when the controlling ECU predicts that wheel lockup is soon impending. Basically ABS activation would mean your brakes are doing their job. The tires may not have enough frictional coefficient with the roadbed surface to keep them rolling.

Personally I have ALWAYS been of the opinion that in highly tractive conditions ABS is, can be, more of a detriment than an asset. Some year ago I always pulled my ABS pumpmotor fuse during the summer. The simple solution for all of us, all around, would be to disable ABS unless the stability control system indicates that stearing control or correction is needed.
