Just brought a 1" Master cyl and brake booster, Been told its a genuine BT1 item. Im upgradeing my diff from drum to disk brake rear. been told i would need one of these. I got home and looked under the bonnet of the calais and its smaller then the one i just brought and it has disk all round. I then had a look at my Berlina and noticed its the same as the one in the calais. Will this brake booster fit into my berlina, it looks way too big, what needs to be changed to make the 1" set up fit. or is it not worth it and just put a disk rear end in with out changing the booster? Any help will be appreciated! Thanks Ben Some original photos have not been recovered yet.

its just, bolt and un bolt then bleed. it all fits perefectly.

Even though the booster looks like it goes way further back into the firewall. I was more concerened about the front bracket needing to be moved.

Front bracket just needs to be bent the other way. Stick it In the vice and bed it the other way. Once you fit your booster and master cylinder you'll see what I mean.

Cheers guys. Appreciate the help.
