A dealerships work shop should have one, and if they don't I'm sure someone local will.

it takes like 10 minutes to take the front rotors off

Humm, I have never really taken the time to look and see how they are heald on, but seeing as how the back has half shafts, I think you would have to take the half shafts out to get the rotor off. Or do you???



Well I am not sure, but I know we were going to take my moms rotors off of her honda on the front and put new ones on, and to get the rotor off you had to take the tranaxle out.



OK I just looked at a picture of my front rotor, and it will come off easy. All you would have to do is pull the caliper, pop the grease cap off, pull a cotter pin ou, and back the nut that holds the bearing in off. No problem there, but it might be a pain in the ass if it is the rear.



Still at any rate if you take it off and have it turned and it is warped it will be true to the machine, and if you have it turned on the car it will be true to the car.

yeah, the front rotors were simple to remove, just that back ones were a pain:

you dont have to take the axles out to take the rotors off.





You will need a good impact screwdriver to get the screws off though.

its a pain in the ass.



Those on the car brake lathes arent so the rotors are true to

the car, its so they dont have to take the rotors off cars that are a pain

in the ass to take the rotors off of, ESPECIALLY 4x4 vehicles.

the rear rotors and front rotors are held on by two phillips head screws.



get a big screw driver, and an impact gun. got a socket that fits the end of the screwdriver, and hammer away. it works rather well.

avoid, you might want to take a look at the rotor that is making noise. Since you had a caliper replaced it is highly possible that the shop installed the pad backwards. Or they bent the squealer on the pad to make it have that sound. The Squealer is designed for people that do not check their brakes that often, it is a metal tab on the corner of the brake pad that is designed to contact the rotor and squeal when the pad is getting close to worn out. You mention it only made noise when you hit the brakes before and now after getting it back it is doing it all the time...this worries me. If it is doing it now they may not have put the system back together right. Or like I said they bent the squealer to make the noise to convince you that the brakes are bad.



The biggest question in my mind is why didn't you replace the brake pads when you had the caliper replaced in the first place?



I do not suggest you drive the car too much longer until this is rectifued though, if the pad is on backwards, or your pads are worn down that bad you don't have much time before the full metal to metal contact of the pad and the rotor decide to ruin the rotor beyond turning.



A little preventive maintenance now saves a lot of major maintenance later.
