Howdy All,
I'm chasing the part number for an RGS rear master cylinder also does anyone know of a suitable master cylinder that can just bolt on, should i be unable to source an original at the right price  ;)

Cheers

hard to find a pull-constructed master as a replacement. If there was, I would go for a smaller one (13mm), as 15mm for a single caliper is way to much. If anyone knows of one that fits - let me know. The rear brake on my 1000 SFC is really shit (compared to the Jota, where I changed to a push-master in 1/2 inch => roughly 12mm with a smaller caliper).
 
Best to get on to Motalia quick, it's bound to be the last one on the shelf..........and no more to come. :D
 
Most push rod actuated MCs from a modern Ducati will do the trick. (We're talking RGS here, Lothar! ;))  The major difference is the mounting bolt centre distance, old Brembos have 50mm, newer have 40mm mountings.  Shouldn't be too much trouble to make up mounting plate to suit.

euro twins in melbourne australia have them on the shelf ready to bolt on for 65 aussie dollars(they are on the net and ship worldwide)

I set out to rebuild the master cyclinder on my RGA last year, but found it was dead easy and economical to simply swap it for another.  Go here:  http://shop.bevelheaven.com/SearchResult.aspx?CategoryID=35      for a supermarket of Brembo bits and bobs, all at reasonable prices.  I was especially impressed with BevelHeaven's "button kit" for Brembo floating rotors.  Seem very reasonable compared to the comments I've read about the difficulty one has renewing the SFCs rotor buttons.

Piet, Piet, Piet... What is the SFC's FULL name? Right: RGS1000SFC  :P

Don't the RGS and RGS 1000 SFC do share the same rear brake master setup, a PULL actuation? To convert that to PUSH is not THAT easy me thinks - or do you have a picture on how to do that, please?  ::)

thanks

No, they don't Lothar.

The 2 bikes have a totally different rear M/C set-up!

Ups - you are right...:

Mmmhh... not sure that is possible without drilling the SFC footrest plate, but that brings me to the idea of maybe adapting this RGS system to the SFC somehow... Have to think that through...

Anyone a spare RGS plate with all the links etc. laying around?   ::)
 
Thanks for the good oil guys.

Lawrence: I would run a kit through it, however the bore is sporting some scoring, so if i can pick up a replacement i'm on for that (I've resleeved in the past PITA).

Piet: I was hoping (dreamin) for a direct bolt on.

Paul: That's for me.

Cosi: See who gets there first mannnnnn

Peter,

Brembo has phased outthe 50mm type, 40mm only now.  Can also be found on various 4-valve boxer Beemers, or you stumble over some NOS, doubt it though....

Spares and repair kits are still available, so you might even pick up a scrappy one at a swap meet/jumble.

Please also be aware that the RGS was fitted with 2 types, 12 and 15mm.  The different M/Cs require the appropriate secondary actuating lever (the one that goes through the footrest plate).

15mm M/C; part# 47 222 121 requires lever #43 311 181, 39mm length
12mm M/C; part# 47 222 129 requires lever #43 311 188, 55mm length

Using the 12mm combo works wonders for the rear brake!

HTH,
piet
