changing rotors on a 996

[drbehavior]

Is there a diy for changing the brake rotors on a 1999 c4 coupe. Is it difficult or just time consuming? thanks for the info.

I don't know about a DIY but rotors are pretty easy. The short version is:

1) remove the calipers. This requires a 10mm hex socket and a torque wrench. Hang or support the caliper to ensure the brake line is not crimped or stretched. I use a short bunge hanging off the spring.

2) remove the old rotors. Once the calipers are removed there are two phillips head screws that hold the rotor to the wheel hub. Remove these screws and the rotor will virtually fall off.

3) install the new rotor and put a little copper antiseize on the screws before reinstalling them.

4) reinstall the caliper and ditto on the antiseize.

5) bed the calipers. Some say to use old pads for this others argue to use new only. Take your pick.

I think Loren has a DIY page for this. If not, there was a full article (with pics) in the magazine called "911 and Porsche world" Have a look on their website-The issue in question was a couple of months back and concerned the boxster although Im sure its the same mechanics as a 996.

I dont have a scanner so cannot e-mail you with the article.

Can anybody point me to a DIY for changing my rotors? I just replaced my brake pads yesterday using the DIY available here, and it was a cinch. Plus, getting the parts for cheap from Sunset Porsche made it all the better.

I was going to replace the rotors, but didn't have the right tools. I now know that I need a 10mm hex to remove the calipers. Does anyone have a DIY for changing the rotors in case there is more info that I am missing? E.g., what torque do I need to use to put the calipers back?

Did you try using the Search feature here?

Thanks Loren. I only searched the DIY Articles and neglected to search the discussion forum.

One additional point to add to Loren's description. To remove the front calipers, you not only have to remove the 10 mm hex bolts but there is also a small bolt (8 mm if I remember correctly) that fastens the speed sensor cable to the wheel upright. You need to unscrew this in order to get the caliper off the rotor and hang it out of the way. It's not hard to do but it's easy to miss because it's hard to see unless you work from under the car.
