After the ABS and brake lights came on I replaced the front pads, and rear shoes. The rear drums were out of spec so a few weeks later I replaced the rear drums. The front rotors are fine. A couple of years ago I replaced the wheel cyls with the Chevy conversion. My problem is that the ABS and brake lights are on. What do I have to do to correct this problem?

 

Usually it's the vehicle speed sensor that is bad. It's on the rear diff and costs less than $40 to replace I believe.

i have a 94 and mine was doin the same thing! right on top of the rear diff there is a sensor has two wires goin to it, replace that and your light should go out!

 

Will give it a try, thanks.

 

do the 24 valves have this same thing? mine is doing the same thing but mine is a newer truck thanks in advance

 

Yep, same thing.

I replaced the rear wheel speed sensor and my brake and abs lights are still on, its been 3 years now, I just put electrical tape over them on the dash.

 

Did you try the brake light switch under the dash?

 

yeah, wasted the 13 bucks on that as well

 

Try and reset it. Reset by disconnecting the negative battery cable and reconnect. If problem comes back then it is probably the abs sensor.

 

mine were on for a while and i ignored it ( do not do this ) until my braken went out...needed to replace the hydroboost and the master cylinder
