I just had the 312mm upgrade and the rear disks changed. Now the brake pedal goes straight to the floor, but becomes stiff when pumped a few times. however it slowly goes back down towards the floor when held. Mechanic who changed it is saying its 'definately the master cylinder' - but i recall this working perfect before going to him. Also it uses the same calipers as the standard brakes so MS shouldnt be an issue.
I have read that this could also be down to an incorrect bleeding procedure with the caliper/MS nipple.
has anyone had this issue? & which is more likely?
thanks
