For road bikes a very, very thin smear of red rubber grease. Push pistons in. Pump out again. Wipe clean. Push back. Insert pads. For track I use GT85 but callipers are cleaned, pistons lubed and brakes checked after every track event.
I've always used a large smear of red rubber grease the for my daily as I found in the depths of winter that thickness allows all the road/brake crud to stick to the outer layer and not get near to the piston surfaces themselves. Applied at the piston/caliper 'junction' with the pistons pumped out & cleaned and then push the pistons back in.
Nice shakedown run, ahead of ride to the EMM near Nice next week, to Baffle Haus, just south of Abergavenny. Via Forest of Dean and back on the fabulous Skenfrith Road. What a fun ride
Prototype 3, more compact but does not accommodate other styles of rearset, printing off another now with more clearance for blockier rearsets.
I fitted some helicopter tape to the carbon heel guards, and polished the exhaust. Won’t get a chance to ride it this weekend, so will clean it a bit more instead.
Some minor tweaks to add abit more rigidity, and it fits straight to the s model frame! Last thing to do is add threads and test the angles (metal tech rearset look to be canted forward a tad too much) then I can get some sets made up.
Fitted throttle spacers to the streetfighter fighter which seems a success. Removed the baffles from the exhaust to try and cure the harsh noise. Not such a success
