    Can anyone recommend a firm in Australia (preferably in Sydney) which is experienced in sleeving master cylinders? I want to have a 14mm front brake master cylinder sleeved to 11mm.

    I've done some internet research but the resulting info was pretty old, so I'm hoping someone can offer some recent testimonials.

    I understand that the process was pioneered by Halray of Lismore. The company is still in business, but now only makes the tools and equipment for carrying out the work. I also understand that there are now many clutch & brake shops which offer the service (likely using the Halray gear), but I haven't come across any motorcycle-related reports.

    Imagining the work involved, I thought I might even be able to do it myself. However, there could be some pitfalls which I don't fully appreciate. If the cost is reasonable, I'd rather have it done by someone who has done it before! Any input welcome.

    Thanks & regards,
    James

    It would be far cheaper to find a cylinder from another bike in the smaller size. What are you trying to achive? Do you want it for front or rear? Bit more info would help.
    Brembo make an 11mm brake m/c, also lots of dirt bikes and chinese pit bikes use that size.

    Thanks for the replies all. I am at the 'sleeving stage' because I can't find a suitable 11mm master cylinder. However, this may be an opportune moment to ask for help in that department.

    The master cylinder should be (or closely resemble) that of a Kawasaki KR-1 (14mm bore as standard). This has an integral reservoir which is round and also slightly angled (so that the reservoir is level, despite the handlebars being angled downwards). This is what it looks like:

    Bj1QVan.jpg


    Nissin makes a generic aftermarket 'retro' assembly which looks very similar, but it uses a different type of brake lever and the smallest bore available is 1/2". Kawasaki's recent W650 and W800 models also use a master cylinder which looks very similar, but the reservoir is not angled and the bore is also too big (14mm or 5/8" - can't remember which).

    The brake caliper I intend to use would work best with an 11mm master cylinder. I could use a brake caliper with larger pistons so as to make a 1/2" master cylinder suitable, but that would mean spending more money (on both master cylinder and caliper). If sleeving proves to be out-of-the-question, I could use a remote-reservoir Nissin 11mm master cylinder I already have, but that is not really the look I want. As far as I can tell, the sleeving option is very cost effective and would give me the desired appearance.

    If anyone knows of any 11mm front brake master cylinders which look like the one in the picture above, please let me know!

    I may also try following up some the (8+ year old) local sleeving leads I have learned about so far.

    Thanks & regards,
    James

    Any 'good' machinist should be able to turn up a sleeve to reduce the dia, press fit it to your cylinder and hone to the correct size. Then you only need to drill the fill and bleed holes and buy yourself the right size piston and rubbers.

    You could try these guys they have been around for a while and did excellent work on my car clutch master cylinder.
    If they don't do it they may be able to point you in the right direction.

    You must surely qualify as a Google Search Deity with that - awesome work

    The problem with trying to sleeve to a new size is that there are 2 parts to the sizing of the master cylinder piston.
    The area of the piston is for the correct force on the caliper piston.. larger diameter means slightly less pressure is required for the equivalent pad pressure... and then there is the stroke of the piston (volume of fluid moved). If the stroke or total movement of the piston isnt enough you wont have enough brake force. This is what happens when people change to twin disc setups and dont change from the single disc master cylinder and wonder why their brake performance is worse than with a single disc.
    The other issue is as @Murdo mentioned and that is finding the right piston and seals to mate up to the fluid holes etc in the master cylinder you are going to use, you might get lucky but
    Normally you would only sleeve a master cylinder that was severely pitted so you could go back to standard piston and seals.
    If the Nissin unit is 1/2" (12mm nominal) I would use that.. it will maybe reduce your brake pressure a little but probably wont be noticeable.

    Thanks everyone for your suggestions - especially my67xr for that list :thumb_ups:. Having briefly skimmed over the list, I think most (even all?) of the bikes listed have integral reservoirs, but all of the ones I am familiar with are rectangular-ish. I forgot to mention that an additional requirement is the ability to fit the standard front brake light switch - a facility which (I think) all of the motocross bikes haven't got. All of the road-registerable bikes should have it though.
    I have already obtained a suitable Nissin 11mm piston kit which will work with the KR-1 master cylinder (MC just needs sleeving and a 1.5mm counterbore to fit the piston retaining washer under the circlip). However, there will be some difficulty in making an adaptor bracket for the caliper I originally wanted to use. Although the problem is not insurmountable, I am looking around for other calipers which may be better suited (and hopefully cheap!). As such, I won't be making any firm decisions about the master cylinder until I have decided on the caliper.
    If there is anything interesting to tell, I'll let you know!

    Thanks again & regards,
    James
