I still have them, they are going on eBay. They have new seals fitted
and decent pistons, but for some reason they still won't bleed
properly. I was going to put them on eBay with "condition unknown" in
the advert and see what they fetched. I don't want to sell them to
anyone I know or like.

 

Ok. It's ebay, someone will buy them... and pay over the odds.

 

Bear says...

Pretty much the same caliper, but the later ones won't fit because the
mounting holes are at 65mm, not the 90mm required.

 

Lozzo says...

Having said that, the later 9Rs have Nissin calipers, not Tokico.

 

Bear says...

They are the same calipers as the ones fitted to the previous model
Fireblade.

 

Have to say my 6 pots are lovely, I cleaned the pistons up when I did
the pads, and there was no corrosion anywhere.

As you saw if you try really hard, you can get the lever back 2/3 of
the way. They still stop and don't fade so i'm not touching the fluid
part of them.

I'll get that changed when I put it into the bike shop to sort out the
fuelling/timing.

 

Well, yes, and if I was going to the alps I would get them sorted, as
it was, I took a nice hilly route back from Chimay with plenty luggage
(14 bottles of Chimay and Duvel) and they were fine.

Definitely could do with a bleed, but i'll leave it to a man who does
(have a power bleeder) rather than faff around and try it just on the
lever.

Cheers

Paul.

They won't be, but for some stupid reason they stick and then the lever
comes too far back. Bee's did the same even after a serious clean up
and new seals. The 6 pots really are evil for this.

The lever shouldn't come back that far, at most there should be 10mm
movement and the brakes should be full on. Every pair of 6 pots I've
come across recently have been like this, which is why I swopped Bee's
for TL1000S 4 pots. They are perfect now.

Be prepared for a big bill.

 

Bear says...

My AP Racing 6 pot calipers go one better. As they get hot, the lever
stiffens up and the brakes bite further from the bar. If I hold a
constant pressure on the lever the brakes slow me down nicely, then as
they get hot they *really* bite and can induce some wonderful 80mph+
stoppies without even trying. I have to gradually relax my 2 finger
maximum grip of the brake lever as I slow down.

It's just a shame that discs cost a minimum of 500 quid a pair and are
reckoned to only last 4,000 miles when used on the road. I've done
nearly that now, and the discs are clanging badly. Time to measure up
the bobbins and alloy carriers to see if I can get away with just
replacing those, as the cast iron rotors are perfect.

If you want perfection there's always a price to pay.

 

Bear says...

Just the discs.

I've been told this by two totally different companies now, so I'm
guessing they're both right.

Fully floating discs are prone to wear, it's a downside of the way the
rotors moving around on the bobbins and carriers. There's a bit of
slack and that gradually gets worse over time. They aren't made for the
road and 4,000 is a lot of racing miles, so it's not that bad really.

I didn't get them for nowt, I bought them fitted to the bike. Granted
I'll easily make a fair wedge if I was to out them on eBay, but I'm
loathe to do that because they work so bloody well. It's the first time
I've had truly astounding brakes since I fitted some Lockheed race
calipers and m/cyl to the trick Powervalve engined 4LO 350LC I built in
the mid 80s.

 

I was about to make a questioning point, given that the gixxer K3/4
brakes _can_ be pulled quite a long way back to the bar, before I
realised that, of course, they don't have the 6-pot calipers...

One day in the Alps last month Mike was complaining that his brakes
were spopngier than they oughter be and sure enough his could almost
be pulled back to the bar (when stationary). Once I'd pointed out to
him that he had the span adjustment on minimum, rather than maximum,
reach they were much improved.

Not sure i'd want astounding brakes like that. In the hands of the ham
fisted, wouldn't they be prone to locking up ?

Cheers

Paul.

 

says...

You very quickly learn not to be hamfisted. You become as careful on
the brakes as you are on the throttle. If anything, they've made my
riding a lot smoother.

 

If I could be arsed to go into the garage to check the calipers on the
9R I would do but I never suffered from brake fade on the road or on
the track when I was riding it.

Corrosion? I cleaned the pistons after 20,000+ miles and they had a
bit of crud around them but no pitting. I must have had a one off.

 

Bear scribbled:

If thats Milton Keynes you mean, it certainly caused my ZZR11s brakes
to fade away to **** all just on the trip back from the shop in
Bletchley to mine (about 4ish miles).

(1)60mph dual carriageways + roundabout every 0.5~1 mile doesn't half
warm any brakes up :-\

 

I've come to the conclusion that either the brakes on my old 9R were
just one-offs when it comes to that particular type of caliper or I
don't brake as hard as I perhaps could.

It's well known on here that I changed the discs and pads for EBC
items on my old bike and left the calipers as standard but it was a
solution that worked well for me.

 

Andy Bonwick says...

You were just lucky. As an experiment, I've been squeezing the brake
levers on every bike fitted with that model of Tokico 6 pots in bike
dealers all over my sales area. I haven't found one that doesn't come
back at least half way before the lever gets hard, and most will come
back almost to the bars when squeezed hard.

lol, nice one and so near to the truth you wouldn't believe it.
