That four pot Tokico front caliper

Vlad, ill be in touch re your 6 potters. will refurbish, new pads and hoses in not too distant future. i like the originals, never been a prob for me. just lucky i guess. maybe its all the free brake cleaner i borrow from work. only borrow, not steal.

It's called stock relocation

Noticed brakes were binding as I have to reverse 10 metres from my garage to the drive and its only a few inches spare each side ( house extension was built making sure could get a bike to the garage ) I cleaned my callipers and bled my brakes- no air bubbles but lever feels much firmer - surprising how much crap there was and only 1500 miles since last clean and I only ride in the sun now I am retired -  road test after rush hour when its cooler 

Not binding now and excellent stopping power - best since had the bike ! May b becos Mrs Notty helped pumped the lever - she asked for £42 labour so I offered to sleep with her tonight as payment - she wants the money instead !! see what happens after 44 years of marriage ! Lol

Starting price is not bad

oooh Steve from Nottingham, pistons look like they'll need a bit of work!

Before I purchase 4 pot calipers, I read (on old org) what piston area summary is bigger than standard 6 pot calipers pistons area. In my eyes, slightly bigger area is better, cause it's easier to regulate padds pressure to rotors, so braking is better controlled. This was my major argument, when I make a purchase.

Now, having 4 pot calipers taken apart, I measure pistons:
4 pot 30mm + 34mm (actually 30.2 + 33.9)
6 pot 24mm + 27mm +27mm (correct me if I'm wrong)

Simple calculations and I have a prove 4pots area is bigger by...... ~1% Obviously not be a big advantage
At the same time, summary length of rubber seals is 18% shorter on 4 pots then on 6. Not sure it will affect braking...

It would be interesting to compare area of braking pads also, but I do not have 6 pots spare pads, and do not want to theke pads of the bike now.

Anyway, when I will be ready to replace, I will do some test brakings and will compare it wit 4 pots test brakings... Possible, there will be no

I have one question, why not from Hayabusa I gen?
In gsx1400, the fluid works with only one chamber between the halves. I mean the tiny ring sealing the clamp after screwing it on the 4 screws.
In Hayabusa and zrx, when we split the clamp we have two channels of two o-rings. Two channels give better performance which is necessary for braking rather than slowing down.

Maybe that's because hayabusa calipers won't fit 14 fork without making/buying adapter?

The Hayabusa 99 to 07 6 pots aren't great either.

I've had a few Busa's and even brand new and scrubbed in the Busa brakes were never that good.

Poor Busa 6 pots topics occur like poor GSX 6 pot topics.

Mounting points for brake calliper's

GSX1400 - 63mm
Busa       - 90mm

a good set of well maintained set of 6 pots with alloy pistons are every bit as good as a set of 4 pots - the 6 pots take more maintenance than the 4 pots and this is where the issue arises - the 6 pots with steel pistons corrode if not kept on top off - the rot starts inside of teh gust seals and makes them swell grabbing the piston causing it to partially seize - so when I rebuild calliper's for folks I have to tell them that you will get a little more movement in teh lever as all the pistons are moving as they were designed

The ZRX calipers won't fit the 14, that was just posted on a German forum.

- the 6 pots with steel pistons corrode if not kept on top off -

The (front) pistons in my K2 are coated or alloy, not a bit of corrosion after 17 years and 57k. Under good light and magnification I can see some striations on the exposed portion of the pistons.
