Haynes suggest that to remove the clutch master cylinder you have to remove
the pedal box and the pedal from the vehicle. On my old 2a I seem to
remember that you could wriggle the master cylinder out of the pedal box
without taking pedal or box off the bulkhead. Am I going to have to take
out the pedal box on the 90 (which makes it a much bigger job) or can it be
done just by taking the lid off the pedal box?

Thanks.

It's not a big job to take the pedal box out.
pull the trim off in the footwell, unclip the spring, 6 bolts out and
you are away.

You are right. Inspection showed that there was not going to be room for
the master cylinder to come out; too close to the bulkhead. I went the
haynes route and took out the pedal and pedal box (which was still bit of a
wriggle round the brake servo and the air filter). Worst bit was getting
the trim out of the way round the footwell to get at the 6 bolts - fiddly,
especially with everything covered in the brake fluid which has been
dripping down the clutch pedal these last few weeks. Took me about 2 - 3
hours in total.

Thanks,

M.

It is possible to remove the clutch master cylinder without removing the
whole pedal assembly, but the bottom bolt is very hard to get at. It is
easier to remove the whole pedal assembly, however, unless the bolts are
seized. All that is required is to remove six bolts (all very easy to get
at) with captive nuts plus the hydraulic pipe. You can then remove the
master cylinder easily, twisting the assembly through 90 degrees as you
lift it.
If you remove the master cylinder in situ, the bottom bolt is very
inaccessible, and you need someone else in the cab to hold the head of the
bolt. Furthermore, removing the whole assembly means you can clean up and
repaint the area where the leaking fluid has stripped the paint, preparing
it to rust.
I have done it both ways and come to the conclusion that removing the whole
assembly is the quickest and easiest way to go. I did the brake master
cylinder this way on the 2a a few days ago.

I've just done one on my 2a and I couldn't get it out without removing
the pedal box.
