Brembo GP4-RX Calipers
|Installed these bad
boys and my first outing at Infineon was a less than the
stellar experience I was hoping for. I guess I had been
spoiled by the Brembo 4-Pad Mono-Blocs I had used on the GSXR K5. At any rate in
direct comparison to the OEM pads I was simply not that
impressed at first. In fact they kinda sucked actually...
The Brembo sintered pads work great initially, but they get hot & I mean HOT. You can't even touch the calipers when you get off the track and once they are at that temp I'm experiencing a level of brake fade that I never experienced with the OEM Tokico with any pad I have tried (Vesrah RJL/SRJL, Galfer, SBS Dual Carbon, OEM, HRC, Carbon Lorraine). They did get better towards the end of the day so maybe there was some additional bedding in required in addition to the process I did a few days ago.
Don't get me wrong I had some massive braking going on out there as Infineon requires tons of super heavy trailbraking so much in fact that I had to sit down and have a talk with my bike that involved a rather large rubber mallet and a 24mm wrench until we agreed on a geometry setting that would work equally well in the heavily cambered areas of the track as well as the flat sections. That my friends is a tall order to fill...
UPDATE: As it turns out the new Brembo GP4-RX calipers use the same pinless sliding pad that the OEM Ducati 1098 monoblocs do so I installed a set of Carbone Lorraine C59 Race pads and INSTANTLY I am back in business. I have been using this C55/59 Race Compound pad for a couple seasons now in the OEM Tokico calipers and love them and now I have the best of both worlds. The precision of the Brembo calipers and the initial bite without fade of the Carbone Lorraine's. I am a happy camper!
Next upgrade is the HP Full Floater Rotors
As with so many of my articles the idea behind sharing this much info comes from multiple threads on internet discussion forums so once again instead of typing out the same basic replies once every 2-3 months I decided to put those thoughts down for everyone to view.
