So i replaced my master cylinder and brake booster a few weeks ago as the MC leaked and ruined the booster, and since then the ABS light has been on. It wasnt on before i changed them, just after. Any way to reset it? I have no brake issues, just the light. Thanks guys.

 

Did you bleed the ABS unit after you replaced the master? Its on the drivers side frame under the cab. There is a bleed screw just like on the wheel cylinders/calipers.

Its pretty well known that the ABS on these trucks isn't that useful anyways. If it doesn't go out after you bleed the ABS unit, you can fix it like I did by putting a piece of tape over the light.

 

Ha yeah buddy redneck engineering lol
