Brad They were on the E28 (early) 5 series and the 3.0Si (big heavy 1970's luxo-barge) They will fit a proper (very wide) vented disc The E21 3 series had single piston sliding calipers - i.e rubbish. Didn't notice if the 4 spots were alloy. They had two steel fluid inlet lines, so you would need to make up an adapter. Didn't measure the piston size either, but they looked alot more capable than the Volvo 4-spots.

Good news 1. Sumitomo calipers are very readily available on Toyota Coronas and they cost $20 each!, there are two main types, one has a steel fluid line into the bottom of the caliper with or without a bracket and the other has a flexible hose screwed directly into the medial face of the caliper. Good news 2. The above calipers bolt straight onto an early 200B strut - If you get the caliper with the fluid line in the bottom and with the bracket arrangement it will just foul the strut but can be 'persuaded' not to. I assume that they also bolt onto the 240k (270mm disc) strut. Question/Bad news. I think that the single piston sliding caliper has twice the piston area as it's working area since both the piston and the caliper body exert a force on the pads. If this is so, even the stock 1600 caliper has more working area than the Sumitomo. This would explain why (cost aside) late model cars use the single piston sliding caliper almost exlusively Can this be so..... Nick P.S BMW 4 spots have a 90mm bolt spacing and with the right vented disc would fit a Datto. Which disc??? --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email <a href="http://www.ozdat.com/ozdatonline/index.htm">http://www.ozdat.com/ozdatonline/index.htm</a> <a href="http://www.ozdat.com/ozdatonline/listindex.html">http://www.ozdat.com/ozdatonline/listindex.html</a> <a href="http://www.mail-archive.com/[email protected]/">http://www.mail-archive.com/[email protected]/</a> --------------------------------------------------------------------- --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email <a href="http://www.ozdat.com/ozdatonline/index.htm">http://www.ozdat.com/ozdatonline/index.htm</a> <a href="http://www.ozdat.com/ozdatonline/listindex.html">http://www.ozdat.com/ozdatonline/listindex.html</a> <a href="http://www.mail-archive.com/[email protected]/">http://www.mail-archive.com/[email protected]/</a> --------------------------------------------------------------------- This message was sent through MyMail http://www.mymail.com.au --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
