New front Rotor problem
I got a new passenger side front rotor and along with it I got the front brake pads for my 88 GTA L98 5.7...well I take it to my mechanic and on the way home about a block away from my house I step on the brakes and it pulls hard to the right, so I let off and it was still pullin, so I drove to my house and I could smell the pad burning like hot....so I go and see and it and it is hot as hell.....so what could be the problem, the pressure seems fine and so i went out for another drive and it didn't do it, so I drove back from my Gf's house and it did it again, I don't know what could be wrong, can you all help and give me some prices if you can, any help will be appreciated.....AARON

so, you only replaced one rotor not both. one side has a new rotor/pads and the other is old rotor/pads that is worn? I've always heard when replacing one, replace the other, so things can be equal.

Could be a few different things, but I suspect that the condition you are having is related to having different rotor surface conditions from one side to the other.... the one that is new will have a different friction coefficient than the one that has been run on the car previously. This is why most people just get both sides at the same time or resurface both at the same time.....
You may have a problem with the brake hoses as well. They are an extremely common problem on our cars. It is probably not the case this time, but sometimes the hoses are on their way out and anything can put them over the edge - like the fluid movement during the compression of the piston back into the caliper and reapplication of pressure when reinstalled. What happens is that the rubber wears out and the hoses will collapse on themselves during operation causing the calipers to stick or have a delay in application which creates a pulling condition.
Ede mentioned caliper slides and they could be the cause as well so check them out as well.
Good Luck
