Hi all, My cars abs seems to kick in really early, before hard braking, I have decelerted harder on my toyota camry than in my car without abs kicking in.

Also when Im on light braking I feel the brakes are 'biting, letting go, biting letting go ....) keeps doing this until it stops (only noticeable in low speeds)

and if I brake from around 110kph modeately there is a slight vibration in the steering wheel.

any ideas ?

First of all, the vibration and biting letting go sounds like either warped rotors, or a spot where an excess amount of pad material has built up on the rotor surface. Replace the rotors and pads, or have the rotors turned and replace the pads.

That might or might not cause the ABS to kick in early. Regardless, it should be fixed.

Something else that would cause the ABS to kick in early would be uneven distribution of braking force....does the car stop straight, or does it pull to one side?

The biting, letting go - is that once per wheel revolution, or random, or what? The answer will help us in the diagnosis.

hi, thanks for your responses, the biting and letting go, its uniformly spread out, not random.
I have to almost predict it to stop in distance. Its not that bad but noticeable at lower speeds(pulling up to traffic, not noticeable if I stop moderately.)

the car is not pulling to one side while braking

From your description, I agree with JM1FD - fix the obvious brake problems first, then see if you still have the ABS problem.

I agree, sounds like you have a warped rotor/rotors to me as well.
