DIY Front Rotor Question

[415RS6]

I'm going to change my front pads and rotors and was researching the methods to it and I read most people take the caliper off from the allen head bolts (http://www.yellowdogracing.com/Audibrakes.htm). Do they need to be changed out each time they are removed? If so does anyone know the part number for them?

Thanks!

You don't need to change these bolts. They are not a stretch bolt and although there is certain to be torque value written down in some manual somewhere, I have NEVER torqued a bolt holding on a brake caliper in the 100+ repairs I've done.

^ what he said.

Changed many times here to. Never torqued to a spec if there is one. Never had troubles. A tip for you though: have a small strap ready to hold the caliper after you remove it from the axle. It's big and heavy. Probably shouldn't have that much weight pulling on the brake line. Tie the strap around the control arm to caliper.

We used a wire coat hanger to support the caliper.

The YellowDog writeup is really good.

Did you FREEZE your rotors?

That is how I did mine. No, bolts are not TTY. New ones can be purchased at a high end fastener supplier-- maybe $6-8 per bolt?

It is our thought that the OE torque spec on the allen bolts are too low. My race car mechanic friend torques them to 55-60lb/ft (dry) on Porsches and Ferrari's. Either the caliper carrier bracket or caliper to carrier bolts (allen) that mount into aluminum should be torqued with a torque-wrench, unless you are very skilled.

There was prior discussion on this topic a year or two ago, that may have been more detailed-- but that's the gist. A search might find it.
