Brake Problems

[n00b on demand]

I went to the shop to get my front brake pads changed. The guy said i needed new front rotors because they had grooves in em...so i was like just change the pads...so as he was doing this they called me back in and said i need a new right front brake caliper. He said something about how it wasnt retracting and the reason why i wasnt noticing it was because i barley had any pad. He said he wouldnt even take it home...and it special order part and its couple hundred bucks ....so i said put it all back on im going home. The weird thing is the braking doesnt feel any different than the first day i got the car. Always had to put a tiny more effort into stopping the car. There is no vibration or pulsations when i brake either. Even when i brake from 65 MPH its smooth. Me and my mom had a huge fight about the car so maybe its time to let it go. Its just not worth it if I'm going to fight with family over it. I hope this is nothing major.
