Betting someone can describe the part and point me to where I find the ABS sensor please and thanks? Some one told me a while back there was a bearing in the master cylinder that can stick cause ABS light to stay on or something to that effect which is what I am addressing.

There is a float, not a bearing, in the brake fluid reservoir, not the master cylinder. It is for the red brake light, but will trigger both if ABS is equipped, and the fluid level drops low enough. If your red light is off that isn't your problem.

There are three sensors. One in the rear diff, and one at each front wheel. The one in the rear is easy enough to find. It sits on top, just to the driver's side of the center line. It is the only electrical connector on the rear axle.

The others are similarly easy to find. Remove your front wheels and follow the only wires going towards the brakes. The sensors stick through the knuckle near the axle shaft.

Thanks, what is the best advise you have for this float if it can stick given it seems like the first thing to check, can I reach it from the mouth of the reservoir?

Yeah, it pretty much takes up the whole mouth of the filler, but like I said, that should only be considered a candidate if your red brake warning light on the dash is on. If that light is on (something you haven't addressed) it should be your prime suspect.

Yes I should have explained that the abs indicator was on always before I parked it a couple years ago, bringing her back to life and had to replace rear break lines and bleed, however, brake indicator remained on afterwards and perhaps I didn't bleed enough even though I am experienced with that process.

Yeah, check fluid level, check that the float is floating.

Got the float sorted insuring movement, took electrical leads off and put wd40 to the socket, break indicator went off, abs remains lit, later found main line to the rear sprung a leak and replaced so far so good.
