Bought mine from a Fleabay trader, Sealey brand but similar to this one http://www.ebay.com.au/itm/1L-AIR-BRAKE-BLEEDER-KIT-PNEUMATIC-CLUTCH-VACUUM-HYDRAULIC-FREE-EXPRESS-SHIPPING-/291133282523?hash=item43c8e558db:g:CNQAAOxy7nNTWyg-

OK. Just been to Perth Brake Parts. The base of the reservoir is 40mm dia. The "O" ring they provided is 39mm ID and 2.5mm thick (my measurements with freeby plastic gauge) and fits perfectly. Their part number, if it is any help is BS129. Cost AUD $3.00 inc GST.

Just checked the part number:- Bs129 2.62mm Section 39.35mm Bore EPDM Rubber O-rings

PS Have I said how much I love my compressor and vacuum bleeder. Took longer to fit to the hose than to bleed the brake, well almost.  :LOL:

Sorry for the refloat. Are these measurements the right ones for the brake & clutch reservoir (39,5x2,62 EPDM). Any source for these? None of the regular o-ring shops I?ve been to have anything similar.

Thanks!
 
It is the right size for the reservoir on the rear mastercylinder on my 3CL. My front mastercylinder is solid aluminium and does not have a separate reservoir.

Easy to find on the net if you can't find a local supplier. I took the reservoir into a brake parts supplier and they found the correct size "O" ring.

Got them! It?s (as @davo said) 35mm. Paid 1 euro for each of them. I took all 4 available on the shop, so I have 2 freebies left for whoever needs them, as my needs are covered for the next 35 years.

I?ll put them in an envelope, and send them anywhere. First come, first serve.

Regards,

Carlos
