new rotors

[4406pack]

I have a question, does anyone know what the torque specs on the screws holding the rotors on, i just got my slotted rotors and want to change them this weekend...any info would be a great help...
thanks

7.2 ft. lbs. according to Helm's, but I am interested to know how you measure the torque on a screw?

[4406pack]

very carefully?

thanks for the info, now if i can just figure out how...

I tried to take my front rotors off but the single screw didnt wanna cooperate with my impact driver. I would probably have to drill it away to get the rotor off. I did it cause I was going to pain and recondition the rusty parts of the rotor, not that they were worn out. I ended up painting in place. I wish you better luck but be prepared the screw sits tight. Might be a good idea to use some sort of rust removal sticky removal fluid thingy.

easy, you get your tq. wrench and put a socket in that is big enough to accept the detachable screwdriver bits, and your set to go.

I am a bit novice of a mechanic but under the wheel wells is kinda my place. If im not mistaken I dont believe you are supposed to use an impact on that particular part. I could be wrong but thats what I always thought.

You can probably get it loose with a manual impact driver, the type that looks like a fat screwdriver and you hit it with a hammer. I use one on motorcycles all the time.

I was thinkin pneumatic impact.

I just changed my rotors again this weekend. I sprayed Liquid Wrench on the 8 screws and let it sit for a little while. The first set where a little difficult, but I used the same method I did years ago when i went to the slotted and driller rotors- a large Phillips head and a sledge hammer to pound it into the screw. I still couldn't put enough torque on the screw driver with my hands to I got a large vise grip and clamped it to the base of the metal below the handle of the screw driver and used that to get so leverage. Holding the screw driver with my chest, my left hand holding the rotor (so it wouldn't turn) and using my right hand to hold the vise grip, the screws came loose.

It would be a little easier with another set of hands or Mrs. GM3 sitting in the car with her foot on the brake, but I didn't want her hands in there to get hurt, and I didn't think she wanted to sit in a car sitting up on four jack stands. The rears could be broken loose with the e-brake on.

luckly for me, my rotors were not that much trouble, the impact driver worked perfectly...

I used a craftsman easyout they work great and if you dont have a set for $20.00 you should get one. The screws are used only to center the rotors, ( the lug nuts have a looser fit and can make the rotors a little off centered), so when you reinstall them they only have to be snugged with a screw driver. The 5 lugs you are going to install in a few moments will secure the rotor in place just fine. I personally did not reinstall them and dont feel you need them at all. Really if you reinstall them dont torque them real tight they cant go anywhere, can they.

I know one guy who tracks his car often and he doesn't use the screws at all. Has had no problems.

I have a set of 'Easy outs', but I was afraid I wouldn't be able to use the screws again and I didn't want to go screwless.

I used a cylindical drift or punch the same diameter of the screw head and gave it several good whacks with a hammer. The impact and or vibration helped to break them loose. Of course if you have a hammer type inpact driver that may well work better unless it slips then I'm pretty sure you'll have wrecked the head.

Make sure you use a good tight fitting screw driver and apply good pressure pushing in as you will only have a couple shots at getting them out without stripping the heads, then you'll be enlisting the help of Mr. Drill and his co-hort Bit.

Reinstall snuggly, I put an anti-seize lubricant on the threads before reinstalling, don't know why they go ballistic at the factory when they tighten those. Guess it helps send people to the dealer for sevice... A very light coat of oil applied with a rag to the rotors, both mating surfaces, and other mating surfaces makes future work easier as well.

the proper way to measure 7.2 foot pounds of torque ( standard torque for 6mm bolts) is to use a inch pound torque wrench set at 86 inch pounds. it would be hard to do on a screw though.

I've been told that they are not really needed either from a Porsche Tech. He said they tighten with heat, so I put them just snug.
