re the pulsing - original aprilia brake hose? if so go for braided

also, it is stickied somewhere on this forum - possibly aprilia workshop section? but bleed them as illustrated there - most mechanics do not seem to know that method - and it works


Let's face it, you wouldn't go to a nurse to get good advice on a problem with a Falco - you'd choose an Engineer or a mechanic...

First thing with pulsing is to make sure your semi-floating discs are (semi) free to move by checking the bobbins between the carriers and discs are free. A bolt through the hole in them and nut on the other side gives you something to allow you to turn them while liberally applying brake cleaner.

If that doesn't work, it could well be pad material deposition (possibly as the pads may not have been bedded in properly).
Someone on one of the forums had his discs bead-blasted and it sorted this out.

If that doesn't do the trick, well maybe your discs have warped. This is what most people assume to be the case when they get pulsing and there must have been a lot of discs replaced unnecessarily as they've not checked out the things above.

Some from the swamplands may suggest pulsing can be cured by fitting braided brake lines .... but I think the vapours from the swamp have begun to affect him. They will do a lot of good things but I don't think that curing pulsing is one of them ....

+1 for D-Rider - any pulsing from the discs pushing back on the pads would surely be exaggerated by braided lines, as some of the pulsing would not be "absorbed" by the rubber hoses flexing? :smt017

My thoughts entirely. It got me wondering how much it would cost to make a production run of 5 or 10,000 seals...

Anyone here with contacts in the seals industry or with a friend in the brakes trade who may know of another makes seals that will do the job?
I tried my local seal and bearing stockist, but they don't stock brake seals. I now intend to try a brake specialist.

Yes - we'll have to form a consortium. Then we can go around 'seal clubbing' quite legally...

I'll get me coat...

More info that might be useful - taken from here:
http://www.ducatisti.co.uk/forum/techni ... liper.html

Try cross reference with yamaha europe spec brembo made calipers, fitted to thr fzr range and the yzf models.
Try Yoyodyne for seal kits-
http://www.yoyodyneti.com/ProductInfo.a ... 20.2799.50

Also heard that suzuki caliper seals fit- Suzuki part #59100-29830 (1 kit per caliper)
__________________
So that may have identified the correct yoyodyne kit for pistons and seals .... maybe the dust seals will be the biggest headache ... though perhaps the suzuki or yamaha suggestions above may include them.


EDIT:

.... and from here:
http://www.speedzilla.com/forums/genera ... ipers.html

I found a source for Brembo caliper seals!!!
I was looking through the parts manual for my KTM 950 SM and the seals are available as a separate part from KTM. The 950SM uses the latest 4-pad caliper, so I don't think that it has different sized pistons like the earlier calipers.

I looked at all of the KTM parts cataloges and it looks like the 2000-2002 KTM Duke II uses the same 30/34mm Brembo caliper as a Ducati. The seal kit is KTM# 58713021000, online price is $16.47

Yes, I forget where I read it but after the lawsuit in the US, Brembo went round all the manufacturers asking if they'd accept liability. The only manufacturer that would was KTM. So if we can establish a KTM part number for seals and/or pistons then we might have a way round this ridiculous situation.

Incidentally, I found a US website which gives a very good run down on Brembo calipers in general. Here's the page for the calipers fitted to the Falco:

http://www.tawvehicle.com/brembo_6800_series.htm

Unfortunately when you click on 'View Repair Parts Table for This Caliper', the table does not give a seal kit part number. Pistons, yes, but no seals. However I'm guessing (although I cannot be certain) that pistons and seals stand a chance of being the same for this model as for the previous model (which coincidentally is the one I'm trying to rebuild). Here's the page for that one:

http://www.tawvehicle.com/brembo_P3034.htm

These have the same 34/30mm pistons, but only the pad mounting is different (single pin as opposed to two pin on the models fitted to the Falco). When you click on 'View Repair Parts Table for This Caliper' seals and pistons ARE available, albeit from the US of A... Which is ironic, seeing as it was the 'Mericans which caused all this crap in the first place. Allegedly.

But, as Andy says, the first step is to check out the KTM angle...

Edit: having googled the part number, this search result comes up:

http://www.bikersjersey.com/product/pro ... px?id=8758

This looks bang on the money for the Falco two pin Brembo caliper...

Just a quickie to say that, having identified the correct part number which matched the piston/seal repair kit I required for my Brembos, I rang up a KTM dealer and ordered them using the part number. Two or three days later the kit popped through my door. Cost £37.15 for one repair kit (i.e. one caliper).

This suited me fine as it was only the outside pistons/seals on each of the two calipers that needed replacing. The inners were perfectly serviceable.

Bear in mind if you need to order similar parts for the Falco that, prior to the SuperDuke and RC8, KTM bikes only had one caliper per front wheel. All the 950cc bikes use radial calipers, so these are not suitable for our purposes, unless you are the fortunate owner of an Ohlins front end with radial calipers.

Falcos use the older style two-pin, two pad caliper as fitted to the 2003 640 Duke II. If you go ordering two sets of repair kits for a bike that only needs one they may smell a rat and refuse to supply you (unlikely, but possible).

Apparently Brembo only supply KTM with repair kits because they have signed a liability disclaimer. Using these kits on bikes other than KTMs is probably breaching the terms of supply. My advice (if you need two sets) is to get one set from one source and the other from a different source. The last thing we want to do is to cause the supply of spares to dry up...

Anyway, part numbers are as follows:

58713021000 (REPAIR KIT SEAL.-RINGS DUKE 02) £8.50
58713019000 (BRAKE PISTON DUKE 2002) £26.74

These parts are shown on the following web page:

I need this info for the raptorchapter too - we also have Brembo seal supply issues - I'll have to check if any KTMs have the same calipers of course - but when I needed new rear brake seals I ended up buying a used caliper - from new zealand!

I'll put up a sticky of the important info from here in the Aprilia section (I have no powers in this part of the forum) - that way it will be accessible to everyone without having to wade through the maze of investigation that led to this success.

I'll probably link this thread from that sticky so that anyone interested can remind themselves of how we got here.

Well done Mango :smt003

Please let us know when you have successfully fitted the spares - that will be the final confirmation for any lingering doubters.

BTW do I take it that as long as your pistons are in good shape you only need to buy a couple of these kits?
58713021000 (REPAIR KIT SEAL.-RINGS DUKE 02) £8.50


Don't think it would be too difficult to get a couple of these - the story being 1 to fix the leaking calliper, the other as a spare in case I need one in a hurry in the future.

I'm going to fit them to the calipers in the next couple of days, but the calipers won't be fitted to the bike and used until the next time I head off for France (these are going on my trusty old VFR that lives in France). That will probably be April time, possibly March (depending on temps).

The calipers I've bought the kit for are the earlier Brembos, as fitted to 916 and 748 Ducatis (single pin), whereas the part numbers I've given are for Falcos with the two pin, two pad calipers.

I could only buy the pistons and seals as a kit, but for the Falco Brembos you can buy pistons and seals separately. Which is nice.

So the answer to your question is yes! Sorry I took so long to get there. And I reckon you could get away with buying two sets of seals, but I'd be wary of buying two sets of pistons from the same place.

Just to bring this thread up to date, I'm now refurbishing a secondhand set of 4-pad calipers to go on the Blue Falco (the red one already has them fitted). 4 out of the 8 pistons have a level of wear/scratches that I'm not comfortable with, so I'm buying a set of 4 pistons and 8 matching seals; i.e. one caliper's worth. KTM part numbers are as follows:

61013019000 BRAKE PISTONS 4X - £41.87

61013019100 REPAIR KIT SEALING RINGS 4X (i.e. 2 x 4 seals - inner and outer for 4 pistons) - £15.01

These parts are common to not only the 4 pad non-radial calipers but also the radial 4 pad calipers, so they are in wide use and should be readily available.

Can I just check double check these are the right one for standard Falco calipers as different parts have been mentioned earlier in this thread?

Thank you
