Brake Calipers - Air Cooled.

[Flat Six Pete]

I was out in the X5 E53 two week ago, Its done 124K (4.4 LPG converted) when there was a vibration on the steering wheel. As the suspension was was up to date and aligned I figured maybe the wheels wanted balancing. When I pulled into the balancing place he pointed out that one of my calipers was sticking, indicated by the wheel bolts being very hot to touch and the whole assembly hot by comparison to the other side. He stated that was my problem. I had the wheels balanced anyway and a new caliper did seem to sort out the problem a week later. Brilliant tow car as in 8 years it has always started first time bar once.

As the 993 is approximately 25 years old and the calipers on that car have never been touched I wondered who here has replaced / refurbished their calipers and the reason?
