I just got done installing after market gears in a 2002 z-28. Now the brakes seem to pulseate and the ABS light is on. Anyone know my problem? Thanks!

Did you put the Reluctor Ring back on the Carrier?
If it's got the Sensors on each tire, check to make sure that Sensors are plugged in.

Did you plug the numbers into your PCM? You need to do that as well. How much of a change did you do?

Thanks for the replies, I'm going to get a little more info on the gear ratio. And try the conections. I'm not sure what I might need to do for PCM.

so you put gears in it and dont even know what ratio you have?

ABS doesn't care about gear ratio, the ring
reluctor or the axle-end reluctors for 4-ch
all turn at wheel speed.

If you had a 3-channel (no ASR) car and you
swapped in a new carrier without the reluctor
ring, you are hosed. These cars have one ABS
pickup into the pumpkin.

If it's a 4-channel car, check that the ABS
pickups are connected back up and not out
of position relative to the chopper wheels
at the hubs.

You need to tune the PCM so it knows what gears you have. It will do that until you get it tuned. When I put 410's in, it was horrible. Low traction light came on at every stoplight and my ABS activated
