Caliper Pins... need to shave 1mm off for new rotors?
« on: April 07, 2005, 03:39:10 PM »
The old rotors for my Porsche calipers were 25mm wide. The new rotors are 26mm. ECS told me that I'd need to shave 1mm off the caliper pins to allow for the wider rotor.

Does anyone know how to do this or what this means? Is this an at-home job angle grinder job or take to a machine shop or brake specialist? Any shop recommendations if so?

1mm seems like you have to be pretty precise with the cutting. I just don't want to get my ham fists in there and shave 1cm instead of 1mm.

Any thoughts?

Okay, I SEARCHED for this all over Google... one of my old favorites AltaVista found it though...I'm supposing I should be able to file these down myself.

If you have a decent caliper to measure your progress, a good set of files, and the time/ patience to make that happen then yes it is a DIY job without question, keeping them round on the other hand might be a challenge!

Andrew, I think we can tackle this tomorrow if we are very careful.  I have a caliper measure so we can make sure to take only 1mm off.  I also have a dremel, but I would use a hand file for accuracy.

All the machine shops i've spoken to are really friendly and talkative until i mention that i need to have brakes worked on. No fewer than four shops have told me no.

The rotors will be here in the next hour or so from UPS so I'll check the clearance then. There shouldn't be a problem since the carrier pins usually have a 2-3mm clearance anyway, the extra 1mm i'd like is to compensate for heat expansion.
