how do you guys usually bleed your brakes on the MKIII? i did the method of pumping brakes 3-4 times and while down i open the bleeder screw.....and close it after fluid flows out.....but i did it and the pedal is still spongy....i did all rotors and pads...and flush out the system using the above bleeding method and of course ihad someone helping me pump pedeal while doing this....do you guys think there still some kind of air trap in the system? help please thanks
