Squishy Brakes...with a twist.

[rawkyjnr]

Hi There,

I have a 1993 Mini, with new rear wheel cylinders, linings and drums and a resealed master cylinder.
My brakes have always felt squidgy, and the rear cylinders were leaking so I changed them. After bleeding them all they are still squidgy (there is no air in there), but when I bleed the RF brake caliper the pedal goes hard like it should be! No air comes out by the way...

However, after about 5 presses of the pedal it is back to its squidgy self. The system is not loosing any fluid at all, but can anyone reason me why this is?

Cheers
