Front Brake Removal/Installation for C4s

[jyoteen]

Does anyone have an image from the tech manuals on removal/installation of the front rotors for the C4s? I got replacement OEM ones. I think I've taken off the calipers (long time ago) but forget the tools necessary, but most important of all the torque specs, if they're specific for the screws.

I'm hoping that the screws aren't jammed. do I use anti-sieze on the hold down screws? Are they really needed? I doubt that, but just making sure.

Thanks.

The rotors are just held on with two phillips head screws. You might have to tap the rotors a little with a rubber hammer. If the screws are rusted or corroded on then just use a small amount of penetrating oil - be sure an keep the oil off anything else.

Impact hammer works too.

You can use anti-seize on them, I do.

I suppose techically not needed as the wheel bolts will certainly clamp erverything together. Hoever if you do not use the screws then the rotors will flopping around as you try to mount the wheel.

Should not be a big deal.... When are you doing this? Where in LA are you located, I could swing by "maybe" if you need a little help..... Darn rain won't let up!

I'm doing it today, of course, if the rain stops for a couple of hours. It's no big deal in terms of helping me. I've swapped out tons of brake pads on Audis and even calipers. I just basically wanted to find out what tools I need before I start tearing in to my only ride to Home Depot. hehe. Oh, I'm located in Highland Park/Mount washington area, and headed to the track tomorrow (Buttonwillow)

Thanks!

You may know this already but you need a size 10 allen to take the caliper bolts off. They're torque to yield bolts so its recommended to replace those. The torque spec on the caliper bolts is 63 ft lbs.

I do not believe that the caliper bolts are torque to yield bolts. They do have a surface finish to them but as far as know there is documentation that they are torque to yield.

If you have a source that documents this I am sure we would all like to know what it is.

I guess I can not say for a fact they are torque to yield bolts but I can tell you the factory service manual tells you to replace them any time you have the caliper off.
