The different sizes are listed under "Automobile Sizes" (Lt. margin on the Speed Bleeder website). If your car is not on it, you may like to send them an e-mail. If the external diameter of the threaded shaft of a bolt is 8 mm (M8 thread, in ISO designation), the width between the flats across the head is 13 mm -- the width is usually roughly 1� times the thread; there is no universally adopted standard here. However, if a spanner has 8 mm inscribed on it, it's for M8 thread fasteners (The Bleeder is a modified bolt). If your car requires part number SB7100 or SB8125, you are in luck, for the Automatic Bleed Valves in the Cicero's link exist in just these two sizes. They are �3.45 each (exc.. p&p), against the American's ~ $10 apiece. You'll need the Valve Caps too. You may think the Speed Bleeder is a very simple device; nothing can go wrong. Not true. Here is one user who doesn't yell, "Hallelujah"! http://www.bmwtips.com/tipsntricks/braketool/bleeder.htm (Under "3. SpeedBleeders") -- Lin Chung.

However, if a spanner > has 8 mm inscribed on it, it's for M8 thread fasteners No. A spanner with 8mm on it measures 8mm across the flats. You just said that a 8mm, or M8 bolt (usually) needs a 13mm spanner. You were right then. Steve

Oops....You are right. It just showed I had not been paying attention to the numbers on the spanners, had never given them a thought. These are the sizes of the jaws. -- Lin Chung.

(BS = Bolt Size). I've still got some lying around. It's occasionally worth a bit of smirking when you point out to someone that what they thought was 18mm is actually 3/8" Whit. And that in the army we presented the retiring OC with a spanner suitably painted and mounted on a mahogany plinth. The spanner was 1/2 Whit :-) Steve |
