Ok....I just replaced my brakes pads and a rotor up front along with installing the gm upgrade in the rear.

The brakes work fine but now I have the red "Brake" light lit on my dash as well as the yellow abs light....I dont have ABS.


any ideas? I ran odb2 and it show no codes.

 

Could poss. be a bad wheel speed sensor front sensor resistance should be 945/1155 and rear 1600/2300 ohms if not then need to be replaced why all of a sudden ? rears are pretty common also jumper wire

 

hmmmmm thats wierd i would check the sensor in the rear diff its a culprit
it gets dirty and will not read

 

I agree with 12vcummins might also add that year truck with man. trans and rear wheel ABS speedo will not work either.

 

have not got a chance to try and fix this yet but did notice the speedometer stays at zero until I hit 25 mph and then jumps right to 25....go below 20 and it jumps to 0 mph....must be the speed sensor on the rear dif
