My rotors on my 2006 Acura TSX need to be cut. The service manual says they should be cut on the car. I assume that a reasonable alternative is to take them off and take them to a machine shop to have them cut. Am I correct here? Is there any reason they absolutely need to be cut while they are on the car?

Also, those nasty screws that hold the rotors on the car - how do you get them off? Impact driver? Do you put them back on or do you throw them out, as I have heard they serve no real purpose other than to aid in the vehicle assembly process.

Thanks in advance for you help.

There are a few advantages to on-hub cutting of rotors in which it ensures parallelism of the friction contact area not just to the rotor, but to the hub itself (in case of hub run-out). I used what's called a Kwik-lathe when I was at the dealer for on-car rotor cutting (I think this is pretty much the industry standard machine for Honda/Acura use). This is probably the only advantage you'll have with on-car cutting of rotors.

The retaining screws can be done away with all-together (I don't keep them around on any of my cars). For removal, an impact driver is used. Sometimes some spray lube before hand to loosen up any gunk or rust that may have seized the screws to the hub.

Good luck with those PITA screws...those stupid screws caused me about an hour of complete pissed offness until my neighbor brought a welding torch over and he melted them out. His idea as he noticed they were brass and he knew the torch could melt them. They are only on there so the rotor doesnt fall off when the car is on the assembly line i beleive.....
