I've once read while installing the rear 6 pistons with 380mm rotor causes a problem of parking brake line being short. It makes sense as the new rotor is larger in diameter and with the relocated parking brake, the distance parking brake line has to travel is greater now. Is there any way to gain some slack on the brake line on f430, without having to gain slack from maybe tapping into the hand brake area? Doing so would create lot of labor to remove seats and center console? Any help would be greatly appreciated. thanks

 

I'd recommend you contact Brembo and ask the question directly. No doubt, they've dealt with this problem in some way.

Problemo solved!

 

How did you solve the problem ? I just had the Brembo front and rear big brake kits installed on my 430 and the rears are grabbing a bit in the back at low speed rolling sometimes, especially at craw speed turns. I believe it's the parking brakes. Would love to hear how you resolved your problem.

 

Remove the underpanel and towards the driver side, there is a adjuster for the stock parking brake. You can gain maximum slack there and you're good. Look at the pic. Hope this helps.
