Just about to sort my brakes out as its warmer, mistyped on eBay and got the Landrover section, plenty of Brake Master Cylinders for 1960's 70's that look just like the one on my 1975 2200 P6, but for a fraction (less than £20) of what the P6 specialists want to squeeze out of us. Whilst the rebuild kit I bought was only around £6, a whole new unit for not much more is attractive. Presumably for a basic unit Girling would have tried to use a standard one for a range of cars - forget that just remembered the rear calipers, however is there a chart somewhere showing alternative compatible parts for P6 but shared with other cars ??
