Brake Servo |
During the week I finished painting the brake servo
and refurbished the operating mechanism. This involved fitting a new
output seal and replacing the felt pads and filter on the input side. The HM
and the instructions with the Lucas refurbishing kit are pretty clear. The
felt pads and the filter have to be cut with a single radial cut to enable
them to fitted around the input shaft. Take care to stagger the position of
the cut when fitting the pads and filter. Assembled the brake
servo and master cylinder. Lubricated the plunger and piston with the brake
grease provided. Sealed the joint with translucent silicon sealant . Set
about making the distance piece that fits between the bulkhead and the
servo. Current thinking by Nostalgia is to pack the servo out with washers
and fill the gap with silicon sealer. The solid plate spacer (diagram 1-16
in the build manual) is a much neater job. A suitable spacer can be
made from 4mm aluminium sheet to the dimension in the manual or using the
servo / bulkhead gasket as a template. Two plates need to be made to achieve
the 8mm thickness required.

Completed the making of the spacer and fitted the
brake servo and spacer to the bulkhead. Sealed the joints between servo and
spacer and spacer and bulkhead with translucent silicon sealer. Connected
the servo input rod to the brake pedal.

Fuel & Brake Pipes |
Between breaks to collect
tools from my daughters and power cuts for most of this morning. I
managed to finally plan and start work on fitting the brake and fuel pipes.
I realised part of my problem was because I am using fuel injection ,
the return fuel line means there is an extra pipe to run the length of the
car and is what makes the routing of the pipes more difficult to avoid
the under floor projections and maintain a neat installation. I worked
out the initial route of the supply fuel pipe using stiff fencing wire.
the enabled me to position the clips in the diff area and work
out the bend angles to line up with the hole in the chassis cross member.
Using one of the copper pipes as a template I positioned the retaining clips
on the inner edge of the chassis rail from the bulkhead to the floor pan.
I then spent the rest of the time working out how to get the neatest
installation under the floor, with the minimum of bends. the Nostalgia
supplied clips won't do it but I know how and where to run the pipes. I
should be able to run the supply pipe straight along the bottom edge from
the bulkhead to the chassis cross member by the diff. The return
and brake pipe will have one bend to go under the floor pan then run
parallel to the supply pipe, then another upward bend to restore the run to
its original line to pass through the cross ember in to the diff area.
Trial installation says it can be done and will look good. I'll
get some different clips from Unimaster tomorrow.

Unimaster don't have any clips so
I'm waiting for Automec to send me a catalogue. In the mean time I
have fitted the front brake "T" piece. Using fencing wire I made a
template for bending the LH front brake line which runs from the "T" piece
to the transition bracket. This gives the approximate position and
shape to bend the copper brake pipe. fitted the LH flexible brake line. Bent
the LH copper pipe to match the template and fitted it.

Front Brakes |
Fitted the RH front flexible hose. Shaped the RH front
brake pipe from the "T" piece to the transition bracket. As before shaped a
piece of stiff fencing wire to get approximate shape and size.
This pipe must be shorter than the LH one by about an inch. This makes the
left and right pipes asymmetrical. Even though I fixed the
LH pipe to the chassis using P clips I will investigate shortening,
re-flaring the end and re shaping LH pipe to get the same shape.

I started by testing the pipe flaring tool I had on a
spare piece of pipe. The result was less than satisfactory. The flare was
just about passable but the tool scored the pipe where it gripped it.
( I had been warned about this tool but ignored the advice, I should know
better at my age. ) The tool is cheap and available from Clarke's ( Machine
Mart) & Sealy. Take my advice and don't use either. I shortened
the LH pipe and took it to Unimaster they put a flare on it for me
free of charge. I ordered a new Tool (this time, definitely not
cheap). The front pipes from the calliper to the transition
bracket on the brake disc cover were too long (as supplied by Nostalgia. I
bent them to shape and waited the arrival of the new tool before cutting
them.

The new flaring tool arrived yesterday. I did a couple
of practice flares on some old tube, - perfect. I took off the calliper /
transition bracket pipes having marked where they were to be cut
allowing an extra 1/4" for making the flares. I had to partly straighten the
pipes to get them in to the tool, but with this done it was a simple matter to
flare the ends and re-bend the pipes. Refitted the pipes. I also
removed and reshaped the LH pipe from the T piece to the transition bracket
because I was not happy with the final shape. Re fitted the reshaped pipe -
much better.

Pedal Box |
I had looked at the fitting of of
the pedal box support bracket before. The holes in the bracket did not line
up with the holes in the bulkhead and the pedal box if the plate was places
flat on top of the pedal box. If the holes were lined up there was an
appreciable gap between the top of the pedal box and the bracket ( in my
opinion too big to fill with sealer. There was also a gap between the front
of the bracket and the pedal box and the rear of the bracket and the
bulkhead because the angles did not match. I decided the best
fit was with the bracket flat to the top of the pedal box. With the bracket
in this position I worked out the angles, and bent the bracket until the
angles agreed. The top of the bracket had an 4mm parallel gap with the
bulkhead I made a distance plate to fill the gap. Now the front holes
needed to be slotted until they agreed with the pedal box. This done and the
fitting checked, the bracket and distance piece were painted. I returned to
fitting the front brake pipe from the "T" piece to the master cylinder.
Using stiff fencing wire I worked out where the pipe needed to be bent.
Once fitted across the front cross member and routed down the inside of the
RH chassis rail the pipe passes through the RH engine mounting
bracket. to get the angles and the route as neat as possible I secured
the pipe with "P" clips and large headed pop rivets. It was now easier to
leave the pipe position to work out the best route. This was
slow work because of all the planning and checking that had to be done to
ensure the bends were in the right place and the pipe was straight and
parallel to the chassis. Bends were made using bending pliers where
possible or where tighter bends were required the pipe was bent round a
socket. I finished up the day making a bracket to secure the
pipe to the master cylinder. I stopped at this point because the pipe
supplied by Nostalgia is too long and I need to thing about clearances and
support of the pipe once the bodywork is in place.

I was unhappy with the pipe work
and the bracket. It looked untidy and in my opinion was possibly spaced too
far away from the master cylinder. Not having a bodywork reference
point I could not tell if this was likely to be the case. I decided to
rework the bracket and the brake pipe to bring it nearer the master
cylinder. I reshaped the bracket by bending a horizontal section in the
middle to bring to the centreline and underneath the master cylinder.
Then I reshaped the the pipe to bring the pipe run closer to the
Master cylinder. The pipe was still too long so having calculated the
bend and the pipe length required to line up with the front master cylinder
connection, I cut the pipe and re-flared the end. I bent a loop in the pipe
around a large socket and teased it in to position. Once in place and
tightened up, I dressed the pipe to get the bends and angles as best
as I could. finally securing the pipe with "P" clips to hold it in place. .
It is still not as good as I would have liked but I suspect it will not be
visible /obvious when the body work is on.

I set out today to finish the pipe
work. Alas it was not to be. I started by bending the rear brake pipe (using
the stiff wire template to start with) around the chassis in the diff area
and down the RH chassis rail. All went reasonably well and the pipe was
loosely aligned and placed in the mounting clips. I left it like this to
work out the bends and position of the fuel pipes. I had
positioned some of the mounting clips earlier. This enabled me to hold the
pipe in place and determine the shape to pass through the cross member
safely and down the chassis rail. I remove the pipe having marked
where the bends should come and attempted the first bend. To my horror the
bending tool flattened the pipe. since this bend was 2/3 of the way
down the pipe it was ruined. Now I discovered the pipe supplied
by Nostalgia was 10mm pipe and all my bending tools were 3/8". there
is not much difference but enough to flatten the pipe. So off to
Unimaster to get some 3/8" pipe. I straightened and cut the new pipe
to length Bent it to follow the chassis from the boot are , down past the
diff and along the RH chassis rail and left it at that for the day
