So Im in the middle of painting calipers, new pads,
bleeders & drilled rotors.

The rotors are each apparently held on by 2 shallow screws.
Cant get them off! I have tried a air impact wrench and a
an impact driver (the kind you hit with a hammer).

Anyone run into this and what to do?
Most cars the rotors just slide off- wonder if I can drill out the
screws.

Thanks, Wayne
 
You really have to wack the Hell out of the Impact Driver just keep hitting it HARD... and they should come loose mine I thought were frozen but eventually the screws slowly came off.


Good Luck

You may have to just drill them out. The first time I did mine, it was no big deal. The second time they would not budge. I finally drilled them out. Just pick a bit a little smaller than the width of the Phillips cross and go slow. You do not need to replace them to put the rotor back on.

For either method, use plenty of spray lubricant first and allow it to set for 15-30 minutes.
 
Once you get the screws off, you don't have to put them back on; they are there to aid in the assembly process (to keep the rotors from falling off when the car’s on the line) and serve no other purpose, so it’s only a one time headache.

Thanks

I have hit the crap out of the impact driver and no good, so I'm off to Home Depot to buy a new set of drill bits to drill them out.

Thanks for the info, I was worried that the screws performed some mystery function.....

I will post some pics when done :)
 
Eureka!

I drilled them out, was pretty easy. Sprayed WD-40, waited
15 minutes and whacked with large hammer-- off they came.

I dont know how to post pics, however I can email one to
someone more tech-savvy if interested- give me your email.

The red calipers, silver NSX logo and the new slot/drilled rotors
look pretty cool if I do say so myself :)
 
Congratulations! Isn't it great to get something like this accomplished. You can attach a picture by using the browse button next to the attach file field just below the post reply field.

You're done now but for anyone else contemplating this:
Once you get the screws out (whether by drilling or conventional!) removing the rotors is easy - there are another 2 holes in the rotor: thread in a couple of M8 bolts (I think the ones that hold on the brake hose brackets are M8 if I remember correctly) - as you thread these in against the hub,it pushes the disc off.

Another tip for penetrating oil for freeing rusted bolts - forget the WD40, get some PB-Blaster! http://www.pbblaster.com/ - awesome stuff!
 
Ditto on the PB Blaster.

Great stuff!
 
Finally done...

Well, it was alot of work, not hard, just steady to do the
painted calipers (red with silver logos), new rotors, pads and then bleeding using the speed bleeders (which are a great product- get them!)

A few useful tips:

1) Make sure you unbolt the brake line support brackets. I did not initially, thought I had enough play, but you really dont once you get the new pads on.

2) You have to push (front) or screw (rear) pistons down ALL the way- no slacking! With the new pads, the unit just barely fits over the rotors.

3) Do a really good job of hanging the calipers off the frame using coat hangers. Make it really sturdy because I guarantee you at the worst possibel moment the caliper will come crashing
down on your leg at some point in the process. You just about get the pads in and ........SHIT

4) The anti-squeal grease Acura uses on the pads gets EVERYWHERE- what a mess. You will have to spray your nice
new painted but covered with grease calipers with Windex and wipe when all done, so done even try to not make a mess.

5) Getting the pads to snap into the spring clips is a bitch.
I found that if I slightly beveled the leading edge of the pads with a file just a little it really helped slide the pads in.

6) Get the speed bleeders and the catch bag- boy, what breeze the bleeding and disposal is with this setup. I remember doing this in high school- what a mess and you always had to get someone to help.

The results look great, IMO. I will post some pics later this week.
 
I replaced those problematic screws that hold the discs on with some stainless steel countersunk hex socket screws, ie screws with a allen key socket, that won't go rusty. I also put them in with some copper grease. I'm hoping therefore they will come out easier next time I want them to.

next time just leave the screws off as the lug nuts will hold the rotor on just fine. :cool:

You sure can, but I would want to wait until later next week as we are installing a new web server and migrating webs this coming week. I'll check back with you on Thursday or Friday. Or, maybe Lud might post for you if anyone wants them posted now.
