SFC1000 front brake

Time for me to upgrade these. Front brake has been like wood since new. I've tried different pads, added braided brake hoses. Discs are in good nick (sort of).
Apart from going to 4 piston calipers (work superbly on my Motodd), can anyone suggest an alternative master cylinder? My current feeling is that one off a mountain bike would probably be better than the stock one...
Thanks in advance.

A seal kit for the stock calipers as well as the M/C often works wonders, actually lets the "wood" disappear.  Saves a fair few bucks, if not satisfied, you can still look for an upgrade...

Andre,

Here is the set up on my SFC 1000.
Works fine with plenty of feel.
Uses the "Standard" Master cylinder.

Cheers
Bruce

Hi Bruce,

What make are your (300mm?) discs?  Also, the discs do not look like they have enough offset for a speedo gearbox and I cannot see one, yet a speedo cable is there?? What have you used there?

When you say a 'standard' m/c, I assume you mean the SFC1000's normal 15 mm size?

Cheers, Andy
 
Not a Laverda wheel and certainly not the stock drive... Ducati?? :D

Discs look like Brembo.

The 15mm M/C is just about perfect for these calipers, same as I'm useing.  Ought to check if the stock M/C isn't 14mm though... iIrc, all post-180? triples got smaller M/Cs, was on my RGS.

Hi Guy's,

Rotors are 320mm Brembo jobs. Ducati I am told.
The Calipers are early 888 Ducati.
The Wheel is an 18" Marvic and the speedo drive was on it when I got it. I suspect Piet is correct, a Ducati one.
Correct, its a 15mm M/C.
This set up has plenty of feel and also plenty of bite when needed.

The brakes on this bike are awesome compared to my stock 81 Jota setup, (but not as strong as the 748R I had a few years ago.) That could be a lot to do with weight!
If I was going to spend any cash on the Jota I would do a similar upgade to the brakes.

Red milled the rotors and put a set of oversize buttons in for me and that stopped the rattling.
Every time I visit him the bike leaves with something set up better.  8)

Thanks Bruce.

320 mm Brembos - hmmmmm.....I have been trying to locate a pair of those with the required 27 mm offset for ages, without success, as Brembo have discontinued them.  Not fussy, a used (but usable) pair would be good, if anyone has any they might sell............anybody????

Hi Andy,

if you really want them, Spiegler in Germany makes you any configuration of brake discs for roughly 435?/pair. I can help on the communication if you want.  ;)

according to the list I looked into, the Bimota discs only have 10mm offset. But you could install them with a distance-ring...

See Lucas catalog,  MSW 211 f.e.
 
Hi Lothar,

The period of Bimota I mentioned have exactly the same disks as required for our old dungers.  In our house are two Bimotas and two Laverdas with them fitted, so I'm pretty well qualified to say. :-)

Having said that, although they work superbly, those old Brembo disks wear out too quickly so if offered Spiegler or brembo at the same price, I'd probably opt for the Spiegler and see how they are.  These guys in America also do a nice floating disk with a flat surface to transmit braking force, no idea if they make anything to suit though. http://www.braketech.com/

steve, your brake tech link has some interesting articles in its 'tech talk' section, inc. the centering of the brake caliper, something sometimes discussed here!
 
Bruce, Piet,etc

I've tried all sorts of pads. Master cyl has been rebuild with new everything. Dont want to go to 320 discs. The 4 piston caliper and 280 floating rotor setup (off an old 851 D****ti) on my Motodd is excellent, so like my missus assures me, size isnt everything...

Smaller bore master cylinder??
 
Andre,

Assuming you still have the P08 calipers.  Have you rebuilt these?  They benefit greatly from a new set of seals, transforms the brake system entirely!  Should already have the lighter and corrosion-resistant alloy pistons fitted.  If fitted with steel pistons, swap them for the later alloy version, saves a couple of grams/ounces while you're at it! :D

Should work almost as good as your 280/4-piston set-up, even with your stock M/C.

If you cannot get hold of an overhaul kit, give me a call...
