I HAVE A 2000 YUKON AND THE PARKING BRAKE LIGHT STAYS ON. I HAVE INSTALLED NEW PARKING BRAKE SHOES, THE SWITCH AND EVEN THE GAUGE CLUSTER. WHEN I SET THE PARKING BRAKE THE LIGHT FLASHES BUT WHEN I RELEASE IT THE LIGHT STAYS ON, ANY SUGGESTIONS?

You mean the brake light? I don't think there's a separate parking brake light correct? You probably have a problem with your brakes period, not necessarily your parking brake.

yellow ABS light or red BRAKE light?
I'm assuming you mean the red BRAKE light since you're mentioning your parking brake in association with it. That being said, which switch did you replace? Again, I'm going to assume you replaced the parking brake switch. So, I would then check your brake fluid level switch. Unplug the connector from the resivior and check resistance or unplug and check for a change, if nothing, jump the wires on the harness side to complete the circuit and see if the light goes off.

sorry i`m so long responding, been away on work. yes, the red brake light on the dash. The fluid level is good and I shorted the wires to the fluid low indicator switch and the light stays on. I have good brakes, its still has me stumped.

Then I would try doing the same with the parking brake switch since testing the brake fluid level sensor had no effect.
Like I said earlier it might not be your parking brake circuit. The brake light comes on if there's something wrong with the brakes OR the parking brake is on. If there's a problem with the ABS then the ABS light stays on. I know you said your brakes work fine but I think it's trying to tell you something is wrong with them. A shop with a Tech2 should be able to check them, and most places will check your brakes for free.
Let us know what they say.

Before you do this, there is something else you need to do. Check you brake pressure differential switch and also make sure both the fluid level and pressure switch have a good ground.
To reverify, it is ONLY your RED brake light that is illuminated correct? No abs light?
