Question about Pontiac Grand Prix
The operation and fitment of the wheel sensors need to be checked. A scan should be run also to see what fault codes the computer has generated because with that problem there will be fault codes generated.
If this issue happened immediately after the front hubs were replaced then I would suspect the problem might be related to fitment of the wheel sensors on those 2 hubs.

You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.

Its the abs sensor, if you encounter an ice patch or snow you won't even be able to stop because the pedal will will push back and make the rip grind noise. If you pull the ABS fuse out, you won't have ABS but you can stop and you won't have the grind noise and back pressure for now. Its safer to not have ABS when the sensor is faulty.

when you pushed caliper piston back dirty fluid traveled through the abs system causing valve to stick ,try bleeding the front brakes and resetting the computer.
