Hey!

1199s with 25K on the clock. Front brake system will not hold a bleed for more than a day or so. By the end of the week, the lever sinks to the bar. When ever I bleed it, tons of air from the master and none in the caliper. No fluid leaks. This leads me to believe the issue is in the Master. I cannot seem to find a rebuild kit for it. I believe it is a Brembo PR16x21 master.

Any ideas? Thanks for the help!

I'm not tight but I replaced my seals with stock automotive cylinder seals...
Part numbers P6968 and KP2114.
Cost pennies from any brake shop.. got mine from the brake shop in Atherton Rob, know where that is >
Just give the cylinder a very light hone with 800 wet and dry, clean it all up and away you go.
