View Full Version : Worn brake rivets. Info required

Hi people

If you can provide good info for me you are assured a place in heaven.

Some Background info:

My discs are good thickness wise and I'm told the cast iron will not be worn by the "rivets" (which are circlipped) but probably the carriers will have wear and maybe the rivets themselves.
These discs had slop from factory and would rattle like a a "German tank division" However mine after 30k has the rattle of nam!
I'm told the carrier offset and bolt pattern are oddball - so no 320mm yamaha quick fix.

My thought is too get slightly over size rivets made to at least help the cause.
Anyone had this issue and got it sorted? Any recomendations?
I don't mind getting new carriers made IF I HAVE TOO but who would do them? -I am fussy so they would have to look mint.

I can actually feel the discs move just as I stop after braking and I hate it!
Although heavy by modern standards the front brakes stop the thing very well.

Regards

Do you have access to any other full floaters to compare them to? Full floaters tend to rattle a bit, especially over bumps in the road.

Have you removed one of the carrier buttons for inspection? Easy enough with the circlip and just a new set of buttons may remove a fair amount of slop.

The other thing I would do before going any further on having new carriers made is to contact Bimota, see what they have available. Maybe rotors, maybe carriers, maybe buttons, maybe they'll not even reply... free to ask though.

Might do that this w/end as the weather is shite.

I'm hoping a set of carrier buttons will cure enough slop at this stage but can't see the anodizing and the aluminuim itself still being mint after so long.
I asked Bimota about a TPS and they got back to me surprisingly..

It looks a very similar setup to my Honda RS125 GP bike

Runing the same caliper too.

If they are the same spec disks, then yes they will move a lot. i have a brand new disk and mine rattles aroudn when im pushing the bike around.

These are the REAL floating disks.. most the other ones have rivits, but they don't let the rotor move at all.

I wouldnt worry about it :)

Basil: Don't mention the v-due. I mentioned it once, but I think I got away with it. So it's all forgotten now and let's hear no more about it. So that's two egg mayonnaise, a prawn Goebbels, a Herman Goering and four Colditz salads....no, wait a minute...I got confused because everyone keeps mentioning the v-due.

Bimota: Will you stop mentioning the v-due?

Basil: You started it.

Bimota: We did not start it...

Hey that's interesting, imdying asked how much I knew about full floating discs as they rattle a lot - I haven't had a look at any others to be honest.
A mate of mine though has a YB10 with mega Km's and he wore his discs out, he said mine is "getting there" I think he used Ducati carriers and spaced them out slightly as the offset is different.

Bimota should never had tried to make an engine from scratch but I give them
top marks for almost getting it right.
All the good work selling "large numbers" of bikes like the SB6 gave them cash
to burn and the V-due seems to have destroyed all that they gained.
I hated the exhaust routing.
Many have been sold with carbs and perform well I'm told.
To get the injection working properly needs lots of dosh but it can be done.

The one thing I cannot trackdown is the cush drive rubbers, they are the round rubber insert type like Ducati or Honda and mine are worn.

I would sell a kidney for a vdue. Any day of the week.

I heard a lot of the v-due stock from Bimota was purchased by a crowd who them fitted carbs and sold them on going quite well with over a 100hp.
A couple of years ago a guy overseas sent me a copy of the review done to the EFI system on the v-due by a very famous EFI crowd.
They must have gone through it with a fine tooth comb, it makes interesting reading as the faults were many but they list solutions to the problems.
Designing a direct injection system for a roadbike by a tiny company was never going to be a walk in the park..

There is a fuel tank on fleabay if you want to start building one :yes:

Body part auction anyone? I'll raise your offer to a kidney/lung combo....
