Ferrari Mailing List: Re: Playing with the 308

[Matt Boyd (ferrari308driver]

Bob,

Thanks for the on-topic posting!

I wonder if you can discuss the caliper rebuilding.  Why did you
decide to rebuild them (what was wrong?)?  What was the cost of
replacement vice rebuilding?  Did you run into any problems
rebuilding?

I've rebuilt calipers once on an '88 Rolls and it was fairly
straightforward, although I had a tough time separating the halves of
the calipers.

Any tips or tricks on the 308?
