How to modify & improve you rear brake for good pictorial guide

2TROKE · May 25, 2013

Everyone who has got a gen 1 or 2 mille knows the back brake is very lacking, is a total bitch to bleed and keep in tip top condition even after you have bled it, and usually within a few miles you will have no pedal again......

I have been doing a lot of researching on the RSV Mille's rear brake and it looks like the best solution to solve the problem once and for good is to install a ducati rear master cylinder on the bike as described by people on other forums swell as on here.

So in have just purchased a ducati 748 rear brake master cylinder for £20 off fleabay.

I have also purchased a different rear brake hose to try and fit off a ducati 750ss also off flea bay for £7 as the original mille hose won't work with the ducati master cylinder due to the 90 degree bend where it exits from the original brembo master cylinder.......I'm just hoping its gonna be long enough as it has 1 straight banjo end and the other a slight angled end

I will try and fit all this this bank holiday weekend and do a step by step how to with pics for all of those interested in seeing the outcome watch this space..........
P.s. also fitting new taper roller head bearings and chain n sprockets with different gearing with step by step pictorials too for those interested.............the missus is gonna love me ....hahaha
NOT!!!

Fitted this set up today and well i'm amazed!!!
Got the old master cylinder off ...compared it to the old unit to double check and it was all cushdie....

I swapped my hose and resevoir off my old cylinder to the new one and it all lined up fine.....
Then took the ducati 750ss hose and fitted the slightly angled end on the master cylinder facing outward and downward routing around the brake lever and in and behind the swingarm into the holding channel under the swingarm

OK so after fitting this all up loose I reverse bled the system using one of these large syringes

Then when I had a pretty good pedal wedged an Allen key in to keep the brake pedal under lots of pressure for 3 hours

Then quickly nip the caliper bleed off and back up once more tight while the Allen key was in place....
And the result is a pedal action I've never had before all the while I have owned this bike ........a real good positive feel and extremely firm pedal.........somehow I don't think the original quite matches up too these different cylinders and as I have now confirmed and some it for myself would reecomend it to any mille or tuono owner who would actually like to use their rear brake to good effect lol

The ducati 750ss hose is a bit longer than original so its good enough too route it away from the hot motor to aid with cooling and the bends on the hose ends are a perfect fit.

From first impressions this mod seems all its cracked up to be ........a bit of testing will tell now if it lasts and doesn't fade like the original ........

Nice one, let us know how you get on after a ride..

Hi,

Just a bit of info from when I had the same trouble.

No matter how many times I bled the rear brake, no pedal at all.

I then took it to a friend of mine, a local bike tyre dealer and service centre and he had a play around and eventually took the rear caliper off and bled it upside down and that fixed the problem and gave me the best back brake I have ever had on a bike where u can really feel the brakes biting and scrubbing lots of speed off when applied.

Done that many times with the original setup.....was still no good like many other forum members have posted.............

Ok headsup for all u ape ridin dudes.......took the mille out today and i can confirm back brake is now superb much better than the original setup ever was......rock solid pedal and loads more feel and power........no sign of fade and its still solid after the ride so all good thus far :doug

2TROKE · Jul 17, 2013

OK bit of info for all u guys n galls ridin Mille's n tuonos if ur back brake has become absolutely spongey with no effect.........I have now been riding with this mod well over a month now and it is as strong as when I first modded it with no signs of fade when hot and still has much more positive feel and power....also passed the mot with flying colours....well worth doing if ur handy with wrenches!!! :thumbup

Looks like a good fix. I just put 5.1 in and it works fine for a year minimum, just reminds me to change the fluid once a year

Wonder if mine has it already as my brake has been fine since I've had the bike about 3k miles riding

Easy to see just whip off ur right hand side middle fairing panel and have a look.....u'll be able to tell if the brake hose exits from the top of the master cylinder instead of the front bud

Sorry to drag up this old thread but I'm half way through doing this mod on a 2009 (Gen 2) Tuono. I've got the cylinder fitted (went straight on) and all hoses connected nicely. I'm having problems with the push rod which seems to be too short to make contact with the piston inside the cylinder and it has a rim halfway up the rod stopping it going any further up the cylinder. Did you use the Duc rod or the Aprilia?

This one http://bit.ly/16U28Ak

There's also a collar on the rod that stops the rod being lengthened too much as it doesn't go any deeper into the cylinder.

I'm sure I'll find a push rod from somewhere that doesn't have a collar and is about an inch longer. Ahiver's look the best so far

Eganov · Oct 13, 2013

Sorry just realised the link doesn't work... It's the brembo one that you've used. Bought new from a duc dealer. Realising now I can't buy the rod from the shiver without buying the whole cylinder etc. What year was the bike you done this mod on?

Determined to make this work

Few pics of my upgrade mod.
Fitted an RSV4 m/c to clean the looks up and get rid of the remote reservoir.
Total cost of the m/c upgrade, including new brake line was less than £30

Anyway...see what you think....it's a Tuono by the way.....here goes.....

Quick question on this, not sure if its anything of not but
on the rear calliper the bleed screw is at the bottom and the
feeds at the top surly that's not right?
