Brake Radial Master

[aka.eric]

Are the Brembo radial master cylinders different model to model?.Seen one for sale but listed as Super Sport 750/900.
Would the bore/ratio for the above work ok on a 888.?
What bore/ratio is recommended.Do you have to change the brake lines to fit a radial.?

[Rushjob]

They do at least 6 different bore / lever ratio's.
16mm bore is for single caliper, 18/19mm for twin.
This may assist for starters to give you an idea what's what...

The cylinders aren't model specific.
There are two bore options though. 16mm for single disc and 19mm for twin discs.
The ratios are x16, x18 and x20. They affect lever travel and feel. 16 gives the most travel and feel where the 20 is like an on/off switch.
The 19 x 18 is the most popular.

It's not usually necessary to swap the lines, but you will need a brake switch/banjo bolt as the cylinder doesn't have the facility for it's own switch to be mounted.

I don't know if you're getting it off eBay, but be careful of eBay 'bargains' on Brembo radial master cylinders, you find people paying up to £190-200 for them when you can get a 19 x 18 one from Red Racing Parts (http://www.redracingparts.com/en/english.htm) for 230 Euros which is about £155 at current exhange rates.

I was going to buy one from Harris at the NEC last week, cos they were doing them for about the same price - until my mates convinced me that it would look out of place on an 888

Jools,

You shouldn't listen to your mates:D

The Brembo M/C is one of the best mods you can do for an 888.


Rgds, Rob

Yeh but, no but, yeh but....

I was bidding on a set of matching clutch and brake master cylinders off a 998R at the time (including a clutch slave which my ST needs), but that bugga 851Neil beat me to 'em :P

Even the road tests at the time were complaining about brake fade, and mine certainly does but I'm led to believe that the cylinder from the 996/998 will be fine and dandy for what I need

Trueeeeeeeeeeeeeeee

Appreciate the words of wisdom.The one in the pic is being sold by Fylde Superbikes,just says for Ducati SuperSport 750/900,no mention of bore/ratio.Thinking that 750/900SS use twin discs,maybe work ok on 888.I,ll ask them if they know the spec.

[Nattyboy]

Hi mate

I use a 19x18 which is perfect (good compromise on feel and used by many top level racers including neil hodgson!). Regardless of the description..fylde will be able to tell you which ones this is as it will be stamped into the unit.

Im about the fussiest blokes there is when it comes to mods to my 888 - it has to be true to the original design and the radial MC fits that bill IMO. Factor in the fact that the original MC is truly appalling (especially for track work) and I think, as Rob says, its one of the best investments you'll make for your bike.

Cheers
Nat

16x20 was the reply from Fylde,so no good to me.Isnt 16x20 the norm for single disc,its listed as fitting Super Sport 750/900,werent they twin disc.
Now you blokes have them fitted so you know what works....but."The racing Brembo radial is 19mm,with the decrease in braking force balanced through softer pads with a higher coefficent of friction.For street use,such pads may not be suitable."
Standard 88-90 851-15mm,most 748/9..-15,16mm,748R-15mm,999-18mm.So if you were guided by above 19mm should result in scary brakes/strong fingers.

eeeek, soz Jools - bike to build and all that, I'm sure you'll get me back...

Brake fade is a pad/disc problem.
I've always used Ferodo Platinum pads and they are superb on road and track. Cast iron floaters also make a difference, £120 off ebay if you wait long enough.

i nearly went for a radial m/c, but then i had to have the matching clutch m/c and they're dear as poison! looked like a bitch to fit, with the res, pressure switch etc. i fit 996 goldline brake and clutch m/cyl's for the price of a brake radial and they bolted straight on. great brakes too (got 32/36 brembo billet calipers).

Jools I maybe able to sort you out a Aprilia RSV Brake mastercylinder and possibly a matching clutch one, They are essentially the same as the Brembo units on a 998R but are in black and not gold.

:lol::lol::lol:

No problems mate, I'm just sorry that me jumping in there perhaps cost you more than you needed to pay :(

I was after the matching master cylinders for the 888 and I was going to put the clutch slave on my ST, cos the ST clutch master was too puny for the STM slave I had fitted so I was going back to the updated OEM Ducati slave. So, that particular auction would've given me everything I needed to sort two bikes out.

Never mind...I got a new clutch slave cylinder and pushrod off eBay the next day so the ST is sorted, that means that I will have a bike to ride through the winter and the 888 has already been put into hibernation.

I know that the 996/998 master cylinders will do the job, but they seem to be quite difficult to get secondhand. I think I will save my pennies over the winter and get the bling Brembo radial pump as Rob and Nat suggest. Red Racing parts seem to be the cheapest so I'll get the brake side done first...I'll get the clutch done to match at some point, but I'm not too fussed about having non-matching levers for a short while..

I think Mrs Jools summed it up 'cos she said that with the ST I seemed to have a never ending wishlist of bits I wanted. She thought that once I got the 888 I would have everything I'd wished for, but she said the other day that she just realised that instead of having my wishes fulfilled I'd now just got two never ending wishlists to try and feed...I think she might be right :lol:

Jools
I've got a pair of master cylinders which I took off my ST4S - same as the 998/996 ones but in black.
Drop me a line if they are of use to you....I mean, you've got half my old bike anyway!

[Jools]

Skids, Rushjob...

Thanks for the offers guys...As usual I'm a bit skint for cash, I was only bidding on eBay because I can indulge my habit of reckless and irresponsible use of a credit card :lol:

But...the original masters on the 888 are black so.....Hmmmmmm
