    Hi all,

    I find my 2007 xx lacking some what at times in the braking department.
    Many years ago I had a FJ1200 and replaced the front callipers with one’s
    from a R1 which where a straight swop that greatly improved the brakes.
    So I wondered what (if anything) would be the best way to improve the
    stopping power on my CBR.

    Many thanks

    With a change of fluid, lines and fitting EBC HH's they should be fine.
    Last one I did the person foned up when he got home and complained long and hard..

    He had grabbed a handfull and did an impromptu stoppie !!

    You canna stop any faster than nearly going over the bars !! :)

    Mr Jaws,...……….thanks for that,
    The next question is to de-link or not to de-link considering
    the cost difference between the hose kits, are linked better
    or just different

    Was that keeping the linked system John or bypassing it?

    It really makes little odds..
    1200Pete always said the following

    If you go fully freighted or consistantly 'make progress', delinking is the way to go.
    If however you ride solo and average most of the time the only advantages of delinking are fiscal when you change the lines, and ease of the job

    That was with linked brakes ..... And I have done the same when I first owned a Bird in 1998 !

    If I may be so bold, in the real world there really isn't any difference between linked and delinked.

    I will qualify that by saying I did over 80000 miles on a standard linked Bird, over 50,000 on a delinked Bird.

    Think I will start with new (Jaws) pads, fluid and go from there.
    with the delinking kit what happens in the calliper are a set of pistons
    not used and blanked off.

    Amazing how you embellish your mileage .....

    Thinking out loud about delinking,
    Would I be right to say that you are going from six pistons to four on the front and if that's the case
    will it not make a differences to the stopping power or am I missing something.

    Has any of you good soles out there got a photo they can post showing the set up of where the
    secondary cylinder and calliper set up is on the front fork leg ...............after delinking
    yours hopefully

    OK , Found one...……...just in case anyone's interested in doing the same and wondered what
    it looks like after delinking

    Is there anything I need to know about before fitting or is everything I need or need to know
    in the kit.

    Ok, here is my experience of linked brakes

    I absolutely detested them on the bird, I ride fairly quickly & never felt fully in control with the linked brakes they always seemed to be doing something I didn't want them to, I do use the back brake for balance quite a lot but when that also brings the front into play it simply didn't work for me & was a real pain in the arse

    When a delink bracket turned up on ebay I went for it & after a bit of advice off here changed the rear master cylinder so ended up with good brakes both ends (don't change it & the rear is like a switch on or off & wooden feeling with it)

    Once the new pads were bedded in & I started going for it a bit again I found the brakes to be much more to my liking (ie normal) but it did show up the utterly shite stock front damping, it could of course been my particular bike that needed the forks addressing but I have ridden 2 more with the same problem

    Having said all that I did previously have a cbr1000 with linked brakes & had absolutely no bother with that at all although it was used purely for touring 2 up so the pace was much less

    On balance I'd still go for delink simply because you can moderate braking force front & rear to suit weather conditions rather than being stick with the slightly daft 70/30% Honda stick you with, we all know that isn't right most of the time unless you like to ride everywhere at 4mph

    Slim63..................Thanks for that,
    I've had the rear shock rebuilt, fitted Jaws springs up front, now turning to the brakes
    (ordered Jaws delink kit + pads) which I have never been that happy with plus I use the
    rear for slow ridding in traffic etc which I must say I think the rear is s##t for normal use.
    What I would like to know is what master cylinder you fitted to the rear and was it a straight

    What rear master cylinder did you use slim, from what bike?

    Slim, I only glanced at Jaws website at these the other day, did you but the circa £110 setup? I seem to remember W there was a HEL kit too but mor expensive?

    Ok gents to answer that little lot ...............

    I bought a second hand delink bracket off ebay for a fiver which saved me borrowing a mates & hacking myself one out of a lump of ally ;)

    The braided brake lines for the front I had made up at a local hose & fittings place for 20 each (that's cheaper than I can make them myself) the rear one I already had

    The rear master cylinder was a Nissin I had kicking around, I'm not 100% sure what it was off & cant for the life of me remember the bore but it was probably off an oil cooled gsxr or bandit as that's my first passion in bikes, either way it was a direct fit & turned the wooden feel I was getting with the stock bird cylinder into a proper brake

    The extra holes in the calipers were blocked off with the original bird banjo bolts & a small stack of copper washers after tipping some brake fluid in there to keep the seals fresh in the unlikely event I wanted linked brakes again

    So that was it, a delink for a total of 45 quid :D

    last thing I seem to remember John (jaws) mentioning that you could lock off the secondary cylinder on the forks to stop the back brake coming into play, I don't doubt that it works but i didn't fancy it myself , if the bracket hadn't turned up I would have just made one to be honest

    This has been debated since time began. Which is about when the blackbird was designed. To further balance the argument I definitely would not delink.

    If the system is well maintained it stops fine in a straight line either solo or two up. The real advantage to me is when you pussy dab the back brake when your brain tells you that you have arrived at the corner a little fast. The difference with linked brakes is that the bike scrubs off speed faster than with rear brake alone. With the fork upgrade done there is no dive or unsettling of the bike and you just wouldn't know that Mr Honda has applied a little front brake for you.

    Unless you are using it for track days leave it alone. And if you are - wtf?

    I have a tendency to trail a little bit of rear brake in corners. Been doing it for decades...don't know what started it and it was practically an unconscious thing until the first day I rode a Bird... :eek:
