Well today I had the day off so I decided to go out and install my new slotted brake rotors that I had bought. The rear rotors came off without much fuss. The front rotors dont have the threaded hole that the rear rotors do to help push the rotor away from the hub. After I removed the 2 small machine screws, I began trying to get the rotor off. I tapped it from behind with a heavy rubber mallet, which did nothing. I then hit it as hard as I could from behind with the rubber mallet, and still nothing. Being that I wasnt going to use these rotors again, I then grabbed my 8lb copper hammer and took a few swings from behind. I hit it as hard as I possible could with the hammer, and nothing. I sprayed penetrating oil arounf where it circles the hub and where the lugs go through, and then had at it again with the copper hammer, again with no results. (yes I was spinning the rotor while hitting it to try and get off evenly.) I then had the bright idea to put the bolts in the caliper mounting brakets and screw them in all the way, which would press against the rotor and push it out. Well I guess I didnt realize how hard I was turning and ended up putting a bolt through my rotor! I backed it off and put a piece of sheet-metal beween the bolt and rotor and tried tightening it more to push the rotor off, and It did nothing. I then tried prying against it from behind with a 3' prybar...and I bent my bar So now I just removed the whoe front hub assembly, and am going to get a new one, because I just cannot get my stock rotor off. I fought with that thing for about 3 hours, and it won. Has anyone else came across this problem?

Nope Just replaced my Front/Rear rotors and Calipers with very little problems at all, I guess it cuase your so far north, (well further than me) sounds like they rusted to the hubs themselfs.....oh well I just reliezed I have to replace my front wheel bearings soon, so its for the better...

Well..while I do live up North, my FC has been garage kept, and never seen winters its whole life as far as I know. My car is practically rust-free.

that sucks dude, 3 hours trying to get a brake rotor off.

you need a beer i'm assuming. I would. good luck getting a new front hub assembly.

before you go and buy a new hub assembly (unless "new" means a junkyard or used replacement) take it to a shop and see if they can press it off first. May save you a load of money.

Just remember to repack the wheel bearings while you are in there. Maybe new dust seals too.....can't hurt.

RotaryExperimental

since you are replacing the rotors, get a good 4 or 5 pound hammer and break the rotor. I will come off. It takes a few smack to break a rotor but a few good wacks should do it.

Hit the corner of the rotor hat (the part that goes to the hub)

i through
just get 2 long screw in the rotor it had two hold for screw.
screw evenly and they just pop out.

The last time I did rotors, I got them off with a couple good swings of a ~3lb hammer.

If you ask me, if they don't pop off by hand or with a hammer... you obviously need a bigger hammer.

razorback

spray wd40 or liquid wrench on the rotor near the lug nuts. let it sit then pound on it in a circular motion.

i work on cars all day and run across this problem alot. get a metal dead blow and slam it from the front. you will see alot of rust and aspestos come out and it will finallay break loose. don't ever let a car kick your ***. never

Since the hubs are aluminum and the rotors are iron, they do not go well together especially in nothern weather. The ones on mine had corroded so much, that I had to take off the hubs and rotors and bring them to a machine shop and have them pressed off. One came off but the other broke in half after 6000 lbs pressure was applied.
All I can say is, have fun!

andrew lohaus

just take the hubs off, and have a machine shop press them out. then, since the front bearing cant technically be reasembled/repacked, soak it in a bucket of degreaser, rinse, dry with a hairdryer and get some sort of a syringe (the kind used for mixing marine epoxy are perfect if you can find some) to squirt in new bearing grease. i had to do mine this way after spending 3 days and nearly nocking the car of the jack stands because i was slamming on the old rotors so hard WITH A CROW BAR. the hydraulic press is your frind on this one

i had to put a little block of wood on mine and hit it with a REAL hammer.

arent you replacing yours? just whack the **** outta the back of them with a normal hammer.

crickifur

I had this same problem myself!!! Heres what I had to do...

I took the hubs off and attempted to press them apart. one rotor busted in half but didnt break the hub the other just wouldnt budge. So, The one that didnt budge, I heated up with a cutting torch. after she was pretty hot I put it back on the press and she came apart. The one that busteded wouldnt even budge with heat, so I cut a slot down the outside face of the center of the rotor (not going completely through the rotor). this released pressure from the hub and one pop with a hammer and she came right apart. All I had to do after that was just clean up the hubs...

Just make sure to check your bearings afterwards to be sure nothing happened to them.

I had another chance to mess with it today, I will let the pictures speak for themselves







All that I need now is 3 new lug studs and a new bearing cap .. I took out the fury of god on that rotor

91mazdarx7

damn i'd say you took the fury of god out on it looks nice though now also i was curious of how you say you have 400rwhp i want to reach that hp to could you tell me your 1/4 track times

My 400RWHP is just my estimate/goal. I will be starting the install of everything within a week or so hopefully, and I will fully document everything from there, with pictures. Im hoping for mid 11's in the 1/4, but drag racing really isnt my thing, so I could care less.

91mazdarx7

keep me updated im very interested to see the outcome

Try taking a little grease and smearing it all over the hub, just a light coat will do.Then put the rotor on.That will help alot when it comes time to take them off.

Tell that to the last person that put them on

lol.I know how that is, i did brakes on my friends TII and i think they were the orginal rotors.thw passenger side came off with a lil fight but the driver side was a pain in the ***.We were hitting it so hard the disc seperated from the part that slides over the hub.

andersonga

hahaha...a testament to not letting a car kick our ***? once again my shenanigans lead me to my buddys house, trying to prepare the car for mountain braking, we decided to replace the front rotors with shiny new brembo's...the rotors (of course) were siezed onto the hubs like leaches and no amount of beating or rust penetrant would help...we finally got the whole hub assembly to come off and took it to our local sears tire place where they pressed it off with much difficulty....i went to work, my friend spent the next 5 hours trying to get the hub back into the new rotor...we got smart ont eh second one, we pulled the hub assembly off first, instead of beating at it from on the car...i sprayed rust penetrant all over the backside and sat there for 45 mins scraping at it with a putty knife and sandpaper trying to remove enough rust to get the hub to slide out easily...then we sprayed MORE rustbgon into it and let it soak over night....i hit that hub as hard as i could with the hammer we had (way too small) and it budged about a millimetre, so we got that one pressed out too...i cleaned it up with a dremel, the corrosion on it was ungodly, and put it back on the car....reassembled everything, bled the brakes, got firm pedal and was putting the wheels back on when i realised they wouldnt turn....the pistons never retracted and the brake pads were just sitting ont he rotor...we put the other wheel back on and let the car roll it, which it did...but you can just hear the pad scraping the rotor...we've run out of ideas and are thinking of replacing both calipers...anyone come across a similar problem?
