ABS light is on 95 GMC sierra k2500 4x4 light was on before i did a brake job on all 4 wheels how do you turn it off

I would think so..

gmc envoy i had done the same wound up replacing all four wheel brake pads and light stayed off

the most common cause is wheel speed sensor or sensor wiring not reading proper wheel speed.it is also possible the reluctor wheel inside front bearing is clogged with rust and debris and unable to send magnetic pulse. This can be tested with scanner to determine wheel in question.ohm meter can be used to test sensor and reluctor pulse.

This is a common problem with these trucks. You will need to set-up an appointment with the service Dept. at the dealership. There is an update for the ABS system. The function of this update is to reduce the sensitivity. When you get down to five MPH (with the brake applied) the ABS turns on (no light on dash) and you get the sensation of Sliding (braking is reduced).
This is assuming that the tires are the same size and pressure, And that there are no defects in the wheel speed sensors. Good-luck and please let me know what you decided to do and how it went.

its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake

There was a TSB on this issue with your Sierra, a faulty or dirty ABS sensor is the cause of this problem. The fix is simple, just clean the ABS sensor at the front hub with brake parts cleaner and inspect the wire leads. At worst you may have to replace the sensor it self. Good luck

what size brake shoes go on a 2 wheel drive 95 GMC SIERRA

More likely to be a rear end issue. If the brakes have been checked I would have your rear end checked. Could turn into a very dangerous situation.

There's speed sensors at each wheel. You may have got some contamination in front of one of them... sounds like the abs is trying to compensate for un equal speed at each wheel... and something may be blocking a proper read at one of the wheels...

The abs light has to be reset by a scan tool.It should not have come on unless the new wheel speed sensor is faulty or you forgot to plug it back in or you turned the key on while the sensor was unpluged.Double check your work before having it reset.Good Luck!!!!!
