Brake questions (kinda long)

[Konstantin Bogach]

Mihnea,

when I have similar situation after changing brake MC it turned out that I
forgot to re-bleed RR caliper after I bled clutch and 4 calipers.  Another thing
I noticed that until I asked my wife to step on brake pedal (I used pressure
method) I did not see bubles. When she did it I got a lot of air out.  I would
get it anyway if I was patient though.  Just applying pressure I waited about 10
min and bubles did not come out.
