Are you sure they are warped? What are your symptoms? Did you bed the pads properly after replacing?
I ask because; last month I drove 500 miles in a downpour. The car then sat for a week in the driveway. When I pulled out of the driveway, the pads / rotors made all sorts of noises and I felt a terrible judder / vibration when I applied the brakes. I thought the rotors were warped.
I took the opportunity to inspect my brake system and re-lube my caliper bushings. To make a long story short, the issue was resolved after going out and following a re-bedding procedure.
What seemed to be warped rotors was just uneven build-up of material on the surface of the rotor.
I did however order new rotors since mine are corroding pretty bad. But until I install them, the car stops on a dime again.
I appreciate the detailed response eldiablo.
Well, in fact, I am not the one who suggested the warping first, I had left my car at my friendly garage specialist for some upgrades during my holiday, when upon my return he said that he noticed that when braking, "the car would have some slight vibration, generally a symptom of warped rotors".
I then drove the car and paid attention, and indeed this is the case. Well, since I didn't notice it before he told me, it is not "that" serious. Yes, the car is vibrating yes, with some strange noise as well.
Unlike you however, in my opinion the car doesn't stop as well as before. I know because there is this straight line near my house, where I know what speed I reach (fast) and when exactly, at which point I need to break just in time before reaching the roundabout in the end, and one day it almost ended badly
. For my casual driving to and from work, the brakes work absolutely fine enough. But their efficiency has decreased, I think I can tell.
I am also concerned that the vibration may damage other parts of my car in the long run.
