Hey guys I just put a 07 zx6r master cylinder hand brake on my f4i with a second f4i rear caliper. It's super stiff & I can't lock it up with one finger & was wondering if there's anything I can do to help or do I just got to get used to it? Any help is appreciated.

 

I had stupid stiff hb and turned out to be shitty ebc brake pads kept crystallizing

 

The master cylinder is about 17,5mm bore so it will be very stiff if you have a one piston caliper for the handbrake. Its even kinda stiff on a four piston caliper, but i'm used to it

So either get used to it or if you want the handbrake softer get a four piston caliper for it or get a smaller master cylinder
