Capri - Brake Booster Removal & Repair

In the last week I actually have been doing some work on my cars as there always seems something has to be fixed or improved. I was very reluctant to publish this post as, at first, I may have looked like a bit of a goose!
It actually relates to how you remove the brake booster.
I will detail how I have done it several times but on saying how painful it was, the guy at the brake specialists asked why didn't I  just undo the four nuts holding the booster to the bracket in the engine bay. I had never considered this but on discussing this method with other Capri owners, all considered this more difficult than the way I describe below. Undoing the nuts behind the bracket would also be quite difficult. If you have some thoughts on this, please let me know.

Removing the brake booster (by removing the four bolts inside the cabin)

Step  1: Remove the parcel shelf. Undo the screws keeping the top of the shelf in place, then the ashtray (2 nuts) & then the bottom nuts or screws holding the tray in place. Carefully pull the tray out trying not to catch it in any places.

Step 2: On the engine side, remove the vacuum hose from the top of the booster. (a few sprays of WD40 might help this process.)  Undo the two nuts holding the master cylinder to the brake booster. I did not disconnect the brake lines but just moved it all sideways & hooked it to the air cleaner brackets.

Step 3: Back inside the car & up under the dash are the four nuts holding on the booster. Three are really easy to undo but the one on the top left is a real bugger. In fact, it has to be located using torches & fingers. It was so difficult to get to that I eventually took the pin out of the clutch pedal & moved it slightly sideways so that I could get a spanner onto it. Once you can see it, it undoes fairly easily. The pictures show one of the nuts but I am not sure which one as taking the photos is also difficult.

Step 4: Back to the engine bay & then the booster with its bracket can be moved backwards & lifted out.

Step 5: Does one have to do all this or can the four bolts holding the bracket to the booster just be undone – all from the engine bay?

Wait until we put it back together.
I have taken to the brake specialists to work their magic but after nearly a week there, they claim to be having all sorts of dramas getting the booster to operate correctly. I hope I can get it back soon.

Postscript.
I haven't finished this project yet, as some two weeks later, I am still awaiting the return of my booster. Not happy! Hopefully this week & I will explain more.
