You need to buy one of these from an Aprilia RSV, Yamaha R1. This one is from an 08 RSV (ebay)

Image

Next you will need a micro brake switch (if the master cylinder comes without one). This one is from a Ducati 749, you can get them on ebay.

Image

You will need to alter the connections from bullet type to male spade type, easy job!! This will save you altering the bikes orignal wiring and can be converted back to standard if you sell the bike on!! Brown wire to brown wire and Blue wire to green and yellow stripe wire.

Image

You will also need this, A radial master cylinder converter kit from HEL

Image

If you are going to fit stubby brake levers, get these from ebay. Looks the dogs!!


Image

You may also need longer tubing from the brake fluid resovoir to the master cylinder, this can be got from www.intobikes.co.uk or www.moto-racing.co.uk

I have not bothered refitting the fluid resovoir and now have an 'uncluttered' look. You need to leave a small section of the tube empty to allow the fluid to rise when the brakes are applied.

Special thanks in the making of this production to Pete (Hey9R) who pointed me in the direction of the master cylinder. Tim my mate who gave me (Gordy price) the micro brake light switch, Gurniman and Steve for pointing out where to buy the tubing from.

The big question is do you like /prefer it :?: And is it much easier to bleed :?: and in use :?:

looks well trick trev =D> =D> but.............what happens when your pads get low and the brake lines use more fluid?surely the m/c will start to suck in the air from your brake tube /res

The brake tube/reservoir did not work :roll: (hopefully will have something from MSS racing Kawasaki that will remedy this sometime this week) In the meantime the correct spec tubing arrived from www.biketorqueracing.co.uk (excellent next day service) so fitted the Aprilia reservoir on.

Random question, but does the master cylinder hit your clocks at full lock?
Having some issues with my nissin 6 pots, reckon it may be that the brembo master cylinder i've got on there at the moment is just a tad too small, so considering putting a CBR1000RR one I've got on if the brakes don't improve quite a bit when the pads are bedded in?

joe what makes you think the brembo m/c is to small?
it all depends on the diametre of you caliper pots and discs as to which size m/c you need

Gal,
When it was on the Toks (which I think have two 27mm pistons and a 24mm piston per side of each caliper, so 78mm per side), the brakes did feel pretty good, and certainly worked quite well, but there was quite a bit more lever travel than I'm used to/prefer.
Been doing some research on the nissin calipers, which have per side a 30mm, a 25.5mm and a 22.5mm piston, also 78mm - found that was quite a surprise when I found that.
At the moment when bleeding, there still appears to be a bit more lever travel than what I'm used to (to be expected really, brakes are from a hydraulic viewpoint the same as the toks - same total piston area). I'll be on the bike riding it in a couple weeks, and will be giving it some time for the brakes to bed in and everything (new pads and all, so hoping it'll improve).
Doing some digging on the internet though, a fairly common upgrade for the older millies (the ones you got the current m/c off) is to put a newer millie m/c on (radial one, like in this thread). It's apparently got a slightly bigger piston which will cut out some of the lever travel, but not so much a bigger piston that you makes the brakes wooden and harsh.
Like I said though, i'll be giving the brakes some time to wear in to see what they're like, if the powers good as the toks i'll be happy, it's just the amount of lever travel to get that power I didn't like :lol:

joe ive been discussing this with trev and it seems we maybe using too big a diameter m/c to get that 'sweet spot'
have a look through this
http://www.vintagebrake.com/mastercylinder.htm
now i know it doesnt include 6 pot calipers but the principle should be the same.

Very interesting site indeed that Gal, trying to calculate some things with it now:
I know both the nissin and toks have piston diameters summing up 156mm per caliper, so per caliper that equates to:
(for the nissins, but the toks total will be the same I think)

Total diameter per caliper of pistons = 22.5+22.5+25.5+25.5+30+30 = 156mm
Area size of pistons in both calipers:
((22.5)^2 X pi) = 1589.625mm^2
((25.5)^2 X pi) = 2041.785mm^2
((30)^2 X pi) = 2826mm^2

giving a grand total for bothcaliper of: 6457.41mm^2,



if we use his 27/1 ratio "sweet spot" we get:

239.163 = pi x (radius^2)
76.16 = (radius^2)
8.73 = radius, so according to this website the guy would want a roughly 17mm brake piston to get the optimum ratio for him.
HOWEVER, upon doing some digging I've calculated the following ratios for the following bikes:
Yamaha R6, 14mm m/c piston, 30.2mm and 27mm calipers = resulting ratio of 33.5
CBR954RR fireblade, 17mm m/c piston, 34mm and 30mm calipers, resulting ratio of 28.45
CBR929RR fireblade, 19mm m/c piston, 36 and 30mm calipers, resulting ratio of 24.33
Ducati 999R, 18mm m/c piston, 34mm calipers, resulting ratio of 28.54

Now from what I know of ducati brakes, they're usually pretty fantastic, and I know that the H###A cbr954rr brakes were by far the best brakes of that years crop of superbikes (the previous gen 929 had had complaints of the brakes being a bit "wooden", hence why i reckon they changed the ratio).
This would suggest that the best ratio is around about the 28.5 mark, if you want a bit less travel, then a bit smaller, and if you want a bit more travel, then go for a bit more.
If i assume then, that i want the same ratio as the H###A cbr954rr with my calipers, then i'd need a:
6457.41/28.5 = 226.561
226.561/3.141 = 72.13
square root that = 8.49mm radius, so a pretty much bang on 17mm master cylinder piston size.
