If you adjust the brake pedal position be careful as one multi owner overadjusted to reduce travel and ended up cooking the rear disk as there was partial pressure being exerted on the rear pads. A proper bleed should reduce the travel but as most have observed its doesn't last also the method of bleeding has an effect.
So the rear has now been modded and the difference is worlds apart. Just to make sure things were ok I founda nice quiet piece of road by us accelerated and hit the anchors enough to get the ABS chiming. First time i felt that on a bike. Quite an unusual feeling but now at least i know how far I can push the braking limits!..... I digress, the rear brake was rock solid and noticeably effective. That should hold me at the traffic lights on the hill! Heres to next time.
Thought I'd add to this thread. I have had the upgrade done about 8 months ago. I would say that there was not a great deal of improvement , still a poor rear brake in my opinion. Recently I swapped my exhaust back to standard, I was running a full Mivv System. Just completed a long trip and noticed fairly early on the rear brake became even worse. What I noticed was that the odd exhaust system allows a lot more heat transfer to the master cylinder than the Mivv which is no where near the rear master cyclinder. My feeling are that the rear brake suffers from a master cylinder that gets hot , expands and causes the long pedal travel fault.
Just bled the rear brake using the Gunson Ezibleed system yesterday. The brake is now really firm and works perfectly, better than it has ever done. I wonder for how long though? We shall see. The Gunson system uses air pressure from a tyre [after letting it down to about 12 psi, because 36 psi is far too much] to pressurise the fluid via the reservoir cap. Then when you open the bleed nipple, fluid flows very rapidly under pressure through the reservoir to master cyl to ABS unit to caliper, and brings the bubbles out with it. It is easy to do single-handed. I took the caliper off first. Incidentally the former Gunson factory was in Stratford, but was demolished to make way for the Olympic stadium & park. They were forced to move away, like many other firms. This is a loss and a sacrifice which seems to have been disregarded during all the Olympic hoopla.
