Brakes and rotors
 
Hey can someone please tell me how to get these rotors off a 1987 rx7 . This is rediculious and my new rotors don't even have screw holes in them ...

the rears are easy as pie..get the screws off them and give a tap and they should pretty well fall off.

The Fronts however will corrode themselves to the Wheel hub and THAT is a total snot bag.
You can do more damage trying to get it off and that thing will just not budge at all!
Too make it easy,just take the whole Rotor and wheel hub assembly to a shop that will press the wheel hub/bearing assembly out of the old rotor.
I say this as I have seen some of your postings and I got the feeling that this maybe over your scope of Mechanical dexterity...no offense intended.

(I had to do mine and ended up cutting and chiseling the hub out..I pronounce myself an expert now..heh..did about 4 more cars after that!)

Just to clarify when you tap the rotor, make sure you are hitting the rotor hat and not the braking surface, unless you don't plan on re-using, then go wild.

Cool thanks yeah I went to my buddy wolfgangs and got the bolts last night . I will be trying that Saturday morning . I have a press at work and that's my next step of the bolts don't work .. they are really really tight it seems . I got so mad I was going to take a torch and cut the rotor right off .. but bolts first then press and then garage as last resort. . Thanks

Because the hubs are aluminium and the rotors are steel...you get the idea.

It can be a royal pain in the ass.

I agree, the best way is to remove the hub and try removing the rotor on the bench with heat, PB Blaster and a big hammer. Failing that, press. If you don't have a press and want them off now, cut them off with an angle grinder.

When you install the new rotors, coat the hub and inner surface of the rotor with anti-seize.

exactly..

I had to cut the disc right off the rotor (where the smooth part starts to go onto the hub...that edge)..
Then with a 2 pound sledge you can whack the shit out of it,all around the cut edges as it is Cast metal and will break off in chunks until you see the Hub.
From there you can support the Hub at the Bearing cup and the inside of the hub and proceed with a flat chisel in sections all around the hub until it loosens up.
It's a bitch of a job..but it has worked for me with great success.
Spray plenty of Lube like Deep Creep (lloyds)..it seems to eat the shit in between the metals rather well.I swear by this stuff....(gaddamn it Fuggin sheet..mudder fragger..lol!)
