Ok, i just did the q45 brake upgrade myself like 2 days ago. and bled the lines and all... my pedal is a bit mushy too.. there's a reason for this. The old calipers were single piston sliding calipers and the new q45 calipers a "dual" meaning 2 piston sliding calipers. It takes more fluid to move the caliper due to the added pistons. More fluid flow is needed in order to move the calipers the same amount as the stock 240 calipers. so, in order to solve this problem i would recommend getting a 15/16 MBC instead of using the stock 7/8 MBC that you have right now. This will give you a stiffer pedal and better brake feedback. good luck
