Hi guys, i have just installed the mperf bbk for my 320I and realised that it is more softer than stock. Send car into the agent for 4 times,but problem until today still not rectify as still feeling abit soft.

Agent let me drive their M135, but still find its bbk still soft. my meaning of soft is i have to step on half the brake before i can feel the braking effectiveness. I thought it should be a slight step will brake fast?

Agent also find my bbk is softer, they have bleed my bbk two times already and coding was done. but now they are recommending to grind the brake pad or otherwise i should drive 2500km to burn in. Yes! 2500km!

my question is this really the m perf bbk braking characteristic. what could it be wronged?
