My Volvo also has the shoes-inside-disc setup and it is quite simple - the shoes are levered by the handbrake cable and the caliper is bog standard. Because the caliper is simpler, it is less prone to problems and it can be overhauled if it sticks or leaks. The shoes are adjusted via a screw that you turn through a hole in the disc - no auto adjusters to worry about. Because the shoes are not in use when the wheel is turning, hardly any wear occurs, so adjustment is only required once in a while. The other advantage is that the handbrake is very efficient, or at least it is on my car :-) ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =----
