I am at my wits end.
I installed the Gros Brakes on my R8 using the R16 calipers up front with Fiat ones up back.
I changed the master cylinder to the 22mm dia (Mecaparts MP2901).
i filled the reservoir using high temp brake fluid (600 deg).
all the lines are new.
I did away with the rear valve, but fitted a proportioning bias valve.
i started bleeding process but after the fluid dropped about 10mm in the reservoir, no further fluid went in.
it seems it is going nowhere, and after pumping for over an hour, still nothing.
i have bled systems before, ( never a renault- mainly holders, fords etc) but this has me totally stumped.
is their anything obvious I am missing or should be doing?
