How do you remove rear brake rotors ?

Every front drive car I've ever worked on, you just remove the rear caliper and the rotor slides right off the hub. What am I missing? Thanks in advance. PS This is an '07 Si Sedan.

I know this is real bad advice to give, when I can't say for certain, that I'm 100% positive, here I go:

I've never seen rotors held on my anything more than a single screw; most of the time (95%+) held on by nothing.

Often times, rotors get "stuck" between all the elements, brake dust, and heat, and often need to be "tapped" off.

Again, take this information for what its worth, and from someone who isn't 100% positive in regards to a Civic.

I have seen many cars where there were two phillips head screws holding the rotors on.

If there are no visible screws the rotor is most likely just tight/rusted. A couple firm taps on the rotor with a hammer should do the trick. The safest way to do this is to hit the area between the lug studs, NOT the surface where the pads contact. If you hit the area between the studs (like you are trying to pound the rotor onto the car) it should pop free.

Edit: Hit this area

I would assume its a single screw. You might need a impact screwdriver. There hard to find but a great tool. I didnt think the rotors were help on with our civics! Hmmm
If you have these screws they can be a pain to get off. An impact screwdriver can work wonders. But if you are having a tough time you can simply drill them out. They are not really necessary.

Thanks guys. I do have 2 phillips head screws in the rotor. I had no idea they held the rotor on. I don't have access to an impact screwdriver though.
Try a regular screwdriver. You might get luckey, I've gotten a few off with just a screwdriver.

However, I have seen these very hard to get off. If you don't have access to a shop full of tools to try just drill them out. They aren't really necessary, like you said, most cars don't even have them.

take the screws out with an impact screwdriver(you must know someone with one, it's an inexpensive common hand tool)with a #3 head, then if it's still stuck on, bang on it inbetween the wheel studs with a hammer, it should come loose. if not, there are 2 bolt holes(forgot the thread/pitch)you can screw bolts into to seperate it from the hub.

In the past, Honda did have rotors that were pressed on. You would need a special tool to get them off.
yes they did, the most common one was the 94-97 accord. at the dealer, we actually resurface the rotors on the vehicle. that's the only model i've seen come through my dealership with those types of rotors. none of the newer honda's have this type.

An impact driver is definately the way to go to get the rotors off. The good news is that if you dont have one, you can get a cheap one for under $20 in most places. You may be able to rent them from Autozone or somewhere like that but I'm not sure.

If you don't have an impact screw driver, get your #3 Phillips head and insert it in the screw head. Tap with a bit of force on the end of the driver and that may help knock it loose.

Good luck!


EDIT: 20 bucks? I'd splurge and get the impact drew-scriver. :biggrin:

the chances of it coming out without one is slim, especially if the car has some miles on it. unless the previous brake job they were just hand tightened. at the dealer, we put them back in with an impact screwdriver too, so they're usually tight.

I've used a hammer and center punch for over 20 years, works very well , less expensive , and most tool boxes will have a set in it already. Make a good deep punch on the outside edge of the rotor set screw , then angle the punch (in the direction for removal ) and give a couple good hits and the screw will come loose . If it slips or gorges the punch hole make another and repeat . You can also use this method for tightening the screw back up .

Actually it's not hard to do at all , and for the average guy an impact driver may be the way to go . But if you do this a lot , it will get pricey and it's a pain replacing driver bits . They will snap off in the screw , and often jam up the screw hole.
