Not sure if this is good or bad. I have a 2003 350z and upgraded calipers to the Akebonos. I have SS lines and motul rbf600 fluid. the pads I am unsure of because the kit was bought used and previous owner does not know the pad brand/model.

I've been through many autocross events and approx 6 track day this year and have not had ABS light come on once. I never tracked my car on the stock calipers so I am not sure if ABS kicks in then, but with the akebonos my ABS light does not come on after heavy heavy braking. I have full braking strength and was wondering if this is an issue. I've tried in the parking lot to go ~40/50 mph and literally stand on the brakes but still no ABS kicking in, I always come to a full stop but never does the car lock up and slide. I am thinking this can be an issue? No pulsation of the pedal either on hard braking

 

Sounds like it's working properly, if not working it's pretty easy to get the tires sliding

 

If the tires aren't locking up from the braking (or, rather, approaching lockup), the ABS won't kick in. The ABS kicks in on sensing of wheel lock, then pulsates the braking to keep the stopping power on the edge of lockup until the condition is removed (the vehicle stops, or less braking force is needed or applied).

Another option is that the upgraded brakes are not really providing enough braking force to reach that point, either. That could be because they have so much braking reserve left, even with the hard braking you've done so far. Or, that they are not delivering their expected stopping power.

Got anyone you can run a stock Z against in a side-by-side stopping match and see who stops shorter to compare?

 

thats a good idea for the side by side stopping match. I was thinking its an issue because my brakes are NOT braking to their full potential and the brakes aren't pushing all the way into the rotor. Again, the braking is amazing on the track with no vibrations and no fade but I was expecting ABS to kick in many times but it didn't.

 

Though not likely, ck to make sure the bulb works. Ign OFF to ON. It will perform a bulb ck.
