I finally did the 4 piston caliper conversion along with 4 powerstop x-drilled rotors and metal master pads. The system was bled twice and there is plenty of fluid. Now the pedal feels "squishy" and goes down way further then before. :newburn:



I am going to try to bleed the brakes again on monday but does anyone have any ideas? Was there a different master cylinder for the 4 piston calipers?? The install went easy, but of course nothing can go totally smooth. ???



WTF!%$#!@$

Make sure that there are no leaks from any of the flare fittings. That's a possible source.

I thought about that too. I can't push the pedal to the floor though and the fluid is still full. It would have to be a small leak then.

If you have a small leak you should feel it on the pedal if you keep it down long enough. I have a 4-piston system on mine as standard I may check for a part number on the master cylinder.



BTW, it would be logical that the pedal goes further since the pistons have same distance to travel as 1-piston system but have much more surface to push so more fluid needed.

I would say there is still air in the system.

Are you sure that you're bleeding the system properly?

Yeah...I am not even doing it myself. My dad owns a shop that I work at. My dad (who has been a mechanic for 30 years) and a mechanic there (who has been a mechanic for 20 years) bled the brakes. We were running short on time so maybe they didn't get all the air out. But bleeding brakes on a 7 is the same as any car, which they do everyday. I am also thinking that I should be the bleeder cause the mechanic who did it probably can't press the brake pedal down all the way since it is small and he has boots on. We'll see tommorrow.
