Looks like it bit a rider on the MV forum real hard at Miller on the AMA course. He got nothing, paniced, went to a 4 finger grip for his next pump and got everything at the end of the long straight...the exact problem I was having. He endo'd and broke both sides of his pelvis.

Exact brake set-up too, stock except for a Brembo MC.

The rider was an experienced racer too, no newbie.

I thought real hard about selling the MV but literally could not sleep over the thought of selling it. I do plan to keep it, but I'll be changing the brakes.

Scary stuff. Not a component that should have any guesswork.

I actually have not ridden the bike since Grattan last year. It was really scaring the shit out of me, and driving me nuts.

I still do not fully understand the problem, but you could not use a double banjo on the Brembo MC for two separate lines until someone just came out with an adapter to bring the banjo out to the front as stock. The stock lines have one of those stupid hoops over the wheel too.

I don't know if it's air in the lines (though garage 10 went through a whole bottle of fluid trying to make sure there wasn't), a problem with those stock calipers or what.

I have found you can get the radial fork bottoms, and Brembo cast calipers for $1400. This is what I might do. The stock mount spacing looks like it's 75mm, and I can't find a modern caliper with that spacing (though that is what I'd prefer, I don't need the bling).

Pretty much everyone hates the stock 6pot Nissins.

Corey's RC has radial mount Brembo's on it and the brakes are phenomenal! It sounds pricey, but that is a great place to sink some money into.

I had billet monoblock radials on my 929. They were truly amazing.

For anyone who wants to try and justify buying them, it can be argued that in some ways they save you money too, I only used one set of pads the whole time I had them!

But the MV will just be a roadbike for riding to cafes, easy rides with friends and co-workers and posing really. No need for them on it unless it's the only option.

wow that is a part you really want to work properly

MV never issued a recall?

No.

He and I have a non-stock combo Brembo Radial MC with the stock lines and rotors.

People with the stock stuff don't seem to complain about a problem other than the brakes aren't that good. Mine came with the Brembo, so I don't know how it worked stock.

That sucks, but I don't get the part about a sharp left hander after the straight.
Hope the guy heals up alright.

Actually if I read it correctly he said that his friend had NOT installed the Brembo as the stock lines would not work. Strange that a caliper would intermittantly fail though

Yeah that seems strange. Could it be the Brembo MC? I dont see how a change in MC would cause the caliper to fail.

I did a similar retrofit on my '03 Duc - The Ohlins forks I bought came with radial mount feet, and I bought the cast Brembos off eBay for about $250. I was very, very happy with this setup using the OEM Duc master cylinder, which is also a Brembo radial job.

Try some superbike lines. No messing around with banjos.

I went back out and measured while not being harped on to come eat dinner.

The centers are 65mm, which is the Ducati spacing.

So, it would appear I can use the stock std mount Ducati 4 pad Brembos as seen on the 998. Buy some adapters and use the 40mm billet Brembos, or go radials.

Hmmm....

I have to use a banjo at the MC, as it is the only way I can get a brake light switch with the Brembo pump. Down at the calipers I don't have to though.

I think the SB lines still connects to the MC with a banjo, but they thread directly into the calipers.

I just went out and checked, that is actually how they are stock too.

I think I'll get a set of these made with a 1-2 T right after the MC.

I think I'll probably just go the Brembo 4 pad std mount, they're only about $450 for the set. And have someone (davef?) powdercoat them "ti look" to get rid of the gold.

Yep, so if the problem is at the Master then the SB Line will not change anything

Naw, that's not it.

It's either the loop over the fender or the stock calipers.

now, i have a brembo radial master cylinder on my setup ( the RC51) and i need to hook up some sort of brake light switch.. is the one that you are talking about seperate? if so do you think i can only get it from MV?

luvtolean

Not an MV part (thank God, as it'd be a fortune!).

You just want a brake light switch banjo bolt.

Something like this:

Pegasus - Double Brake Light Banjo Bolt, 10mm x 1.0 Thread

MAke sure you get the one you need, the right pitch and single or double. Also make sure you'll have the space for the electrical stuff on the end. (I can't run a double on the MV with the current set-up, it'd hit the ram air cover below)

BTW, I know nothing about that vendor, it just came up first on a search.

sweet, thanks! if nothing else it gives me a place to start

Shenders1

I know quite a bit about the vendor, having spent more than I care to admit with them back in my SCCA Formula Vee days. They're good people.

An alternate source is Lockhart-Phillips, which distribute through most cycle shops. Or you can search eBay for something like 'banjo brake switch'. I got one for about $8 this way.

XSIVSPD

cool, thanks for the abundance of help, i didnt even know they made switches like these... i was going to try to rig up a micro-switch on the brake lever somehow
