    Brake Pedal Sensitivity - 4 pot brembo kit

    Sup guys, I'm running a 4 pot brembo big brake setup on my APR stage 2 MK7R. My rotors are 355mm two piece slotted rotors. I'm also running motul RBF660 racing brake fluid. My pads are hawk performance which I just put in a week ago (costed around $200). I'd like to know - how can I make my brake pedal feel instant when applying the brake? I notice my brake pedal requires a longer push to activate the brake compared to a mate's 4 pot TTRS brake kit in his mk7 GTI which requires almost nothing on the brake pedal for a large amount of stopping power to be applied?... does it come down to the brake pads? What should I have in order to have a sensitive brake pedal and feel the stopping power come on with the slightest of presses?
    Cheers guys!

    Did you bed the rotors in when put on? also may need a Different more aggressive pad.

    Yes I definitely bedded the rotors in when they were first installed, drove very cautiously on the pedal for around 400km. I'm hearing from a few people it may come down to the pad... what do you recommend I should be running?

    Its the relationship between the master cylinder and caliper piston area. Nothing to do with pad compound.

    If you've changed calipers to those with larger piston area, your pedal will need to travel further to actuate the same amount of pad pressure.

    I see, thanks for those details sammy. So what can I actually get done to my brakes in order to get the instant pedal feel now?

    Change calipers to those with smaller total piston area, or change the master cylinder to a larger diameter version.

    One of my mates has recommended I buy a AUDI TTRS MKII master cylinder from ECS tuning and he'll install it in my MK7R and that it should fix the pedal response... is this safe to do? Will it fix the longer pedal-push feel and make it feel instant?

    Is it safe to mess with your braking system? would you have someone who isn't a qualified mechanic do it?
