Yamaha One-Piece Calipers

The standard CBR600F2 brakes aren't very impressive.
Modern sportsbikes are equipped with four-pot calipers and have 300mm floating discs. The CBR600 uses floating two-pot calipers and small 276mm fixed discs.
And when you combine those with a fireblade brakepump which is designed for four-pot calipers you get rock hard brakes that need a lot of force on the lever to slow you down.

As soon as Yamaha introduced the one-piece calipers with the blue-anodised caps on the Thunder Ace and Thunder Cat the press was raving about the incredible stopping power they produced. Yamaha even had a special ad campaign about the brilliant brakes. Yamaha uses them on all of their bikes now, from Fazer 600 to XJR1300 to R1/R6. They have changed some minor details over the years, making the design even less complicated.
I have never seen brakes with so little parts, and usually the most uncomplicated design works best.
Well, this is no exception!

I saw a Fireblade with APE brakes that used Harris adapter plates. I was amazed with the simplicity of the design... just a plate and some washers. I immediately knew I could use the same design on my bike because there was little offset between the mounting points on the forks and the calipers (6.5mm if you're interested)

It took me two evenings to hand-make the plates from a 10mm thick aluminum plate, and I used three M10 washers to get the 6.5mm offset I needed. As usual the biggest problem I had was getting proper fine-threaded M10 bolts bit in the end I found some at a breaker. I had to shorten them a bit.
The calipers and the discs are rigidly mounted now, but the original GSX-R750G uses the same setup without problems so it should be okay as long as the discs don't tend to warp.

Connected the brake lines, everything tightened and it's time for the first test-run...

It took a little time to get the pads bedded into the dics, because the new pads cover a larger piece of disc than the old ones, but after braking to a halt about ten times I already felt the pads biting hard and I was able to pull some stoppies... this promised to be really good.

A week later after fitting them I am really over the moon with the new brake-setup. It feels like I'm able to lift the rear wheel/lock up the front at every speed and deceleration is phenomenal!
The fireblade pump is really a very good match to the calipers giving lots of feel and the pads bite very hard... I love it.
Consider it the poor-man's alternative to a APE/PFM/etc. superbike setup.
Who needs six-pot calipers?... these give you all the braking power you will ever need and look incredibly trick with the anodized caps.

BRILLIANT!, ACE!, KILLER!, SUPER!!!!
