    This fits either bike, the disc is the same on all models.

    Bearing in mind the different size of front wheels SE 17", T100 19" - are you sure that not only the discs are the same size but the caliper mounting points on the forks are identical ?

    The ride height is higher on the T100 as well.

    Having thought about this, I'm not sure if my question is relevant ????

    Yeah this is why I asked the question.
    Have e.mailed the seller and he says no probs so will order and leave feedback on this thread.
    Bearing in mind it comes with new pads and brake line, I think the cost is worth it. I have certainly spent more on parts that make the bike go faster!

    The caliper needs to be off a non ABS bike. If you get the later ABS version then you have two brake line connections. The main one operates the top and bottom pistons and the middle one is for the ABS line, so it only works two of the three pots. If you get the older non ABS version there is only one line going in.

    I know because that's what I fitted to my Bonneville SE - just could not get a decent pre- ABS left hand caliper - loads of RH ones for sale! I decided to go with it because the pad area is still greater than the standard caliper so it does result in an improvement. Also, non ABS ones are going for silly money - even scabby ones that probably need a complete overhaul.
    Mine was brand new with new pads and the braided brake line included for £112.00 on ebay.

    That's cheap, I thought £145 was a good price !

    I'll see what's what when it turns up.
    If it needs a second line, I've got a load of spare ones and washers etc in the garage, so I'll add a second one and see what difference it makes. :)

    They are identical, do you think Triumph would machine different parts unless they really had to?

    If an ABS calliper were used, might it be possible to internally connect the separated areas?
    Then only one hydraulic feed would be required to operate all three pistons.:)

    A bit like the OE equipment on a lot of twin brake set ups.

    I suspect that might look a bit neater than having the joint by the caliper?

    I think I might go for the two lines to the one caliper just to confuse anyone looking at it :p:D

    Steve, did you remove the centre piston or leave in position ? did you block the ABS line in with a blind bolt and washer ?
    Will this Caliper bolt straight onto the original mounting and was there much need for shimming ?
    Cheers

    I picked up a Non - ABS unit from eBay recently to fit to my T100.
    I been having a little look at it today with the view to making a start next week probably.
    One thing that has become apparent straight away is the lower mudguard stay actually fouls the caliper, not an issue on the alloy wheeled Bonnies as they haven't got the stays.
    Just needs a couple of small flat brackets fab'd up to lower the front of the stay where it bolts to the fork leg.
    I'll pop up some photo's when I fit them.

    Cheers, Brian.

    Yes it has been done this way, you just drill through and connect the centre to the outer cylinders. Apparently it's an easy fix.
    Only problem is I have never seen it done, and no-one has posted any clear pics or instructions. So anyone out there done this and can post a detailed "How to"?......please.

    A simpler way is to try and pick up a caliper from a later model Honda CB600F Hornet.
    The ABS caliper is mounted on the right hand fork leg, so to all intents and purpose the L/H Caliper is 3 Pot fed by 1 line in.
    I bought mine from a guy in Europe for £42 inc P&P and it arrived inside a week.

    I've just finished refurbing the Caliper, stripped, cleaned, repainted, fitted all new seals and rubber boots.
    New Pads should arrive later today.

    A very satisfying task.

    Ride safe.

    Why thank you kind sir.
    TBH, Dilli it's the result of being retired, bored and to much time on your hands.
    It could be a nice little earner if you could pick up a regular supply of doner calipers at sensible prices.

    One point of interest if you go down the eBay route, make sure the Caliper comes with it's carrier as the Bonneville one won't accept the uprated Caliper.

    Nice job on the refurb, but I already have the ABS type caliper. I don't wanna put two brake lines on, so lookin' for info on drilling out and connecting all pots.

    Yes, I did realise that and tbh if the same caliper as yours had of turned up I'd have gone for the same.
    I believe Steve Lovatt has the same type as yours and has blocked the centre piston line.
    Even with the 2 outside pistons working and the extra friction material of the new caliper I would think the braking efficiency will be improved markedly.
    I had a close look internally at the bores when I had mine apart to see where it might be possible to drill another gallery and it would be quite a difficult task I feel.
    Of course that's not to say it can't be done.
    The centre piston is shallower, so it might be possible to drill at an angle down into the outer piston galleries ???
    I'd be interested to know how you get on.

    Cheers, Brian
