S40 (New) Brakes : My S40 is braking my brain!

[glegalee]

Evening all, the S40 saga continues.

You may have read my previous post about the EPS pump blah blah blah.

I have today replaced the rear coil springs, shocks, lower tie rods and both rear callipers.

I've bled the system thoroughly and have no more air coming out of the bleed nipples however when my wife was in the driver seat as my assistant pressing the brake pedal as per my instructions (press 5 times then hold whilst I release the nipple to allow fluid to flow... repeat) she commented that when she was holding the pedal down before I loosened the nipple that the pedal was slowly moving towards the end of its travel.

I finished bleeding the brakes and jumped into the drivers seat to see what she was on about and sure enough the pedal does indeed slowly continue through it's travel until it hits the end. It doesn't seem to do it every time you press the pedal but there's obviously something not right with the system somewhere.

I've inspected the new calipers and can not see any leaks, there'd have to be a massive leak to allow the pedal to move that much.

I have yet to remove the front wheels and do a thorough inspection at that end but rain stopped play today unfortunately, however I have peeped through the gaps in the alloy wheels and can see the front pipes on which I can not see any evidence fluid leaks.

The reservoir is at the full level and does not appear to drop as if there's a leak in the system.

I'm confused.

Any suggestions would be greatly appreciated.

Cheers Greg.
