Hi Danny jack up the car and use axel stands or blocks for safety remove wheels and open the calliper s. if the park brake cable is attached to the back of the calliper you will need a brake wind back tool. If not the pistons on the calliper should push back to make room for the new pads. Next remove the calliper brackets and then the rotors and reassemble in reverse order. Before you let the car back down pump the brake until its hard then turn the wheel by hand to see that it is free. After a road test jack it up again and make sure the wheels are still free. Have fun. Regards Jim...

blend door actuator failure or vacuum line broke/disconnected.

There is a factory idle screw under a cap on the side of your throttle body you have to drill it out and turn it up a bit

Thank you for fixing my problem

Replace the fuel pump relay.

Pressure on the output shaft. I need to know if this is an automatic or stick? That would help to identify if the issue. Also what is the rpm at the time? Is this more a problem cold or hot? Have you checked if there are others with this issue? If you do a search the problem may be well known. There may be a Tahoe Owners Club online where you can join a forum and get a great deal of helpful info.
