The Rear
For normal road use the rear brakes on all post 1970 Morgans are fine, they can be
converted to disc brakes which will of course dissipate heat faster than drums. I have
driven a vehicle with this conversion and did not notice any vast improvement. The
conversion is expensive and would certainly require some form of restriction to maintain
the front - rear balance and to me there seems little point in improving the efficiency
then having to compensate for the improvement.

The Front
A simple and obvious point here is to make sure any replacement pads are of the correct
compound. As a general rule competition pads are designed for competition and are pretty
useless for normal road use, they wear out very quickly and often have very little effect
until they become hot, this can be very scary around town. I have had good results with
Mintex pads and more recently with EBC who market a special compound pad that does not
give off awful black dust that corrodes your wheels. Both cost around £25 -£40 a set,
the EBC one's are colour coded for appropriate use (Green for road use). I have driven
many cars with both these makes fitted and they are slightly more efficient than the
factory fitted originals.

Serious upgrade at the front involves changing the original 2 pot callipers for 4 pot
callipers, bearing in mind that Morgan have now taken this route without any modification
at the rear, one has to question the front to rear balance of earlier cars fitted with two
pot callipers. Have you ever had the back end lock up first on a damp day?. I have
certainly experienced this in an early +8, it's ok if you are travelling in a straight
line, but I was not! Upgrading callipers is not cheap, you can fit the factory type 4
pots, the difference when driving the car is fantastic, giving a more balanced feel to
the system. The cost is going to be circa £600 as they do not fit onto the original
brackets so you will also require new brackets, flexible hoses and I would always fit
new discs.

A second option is a Mullbery conversion, The kit includes 4 pot billet
callipers, aeroquip flexible hoses, drilled and vented discs and conversion brackets
for the callipers. I am most impressed with the engineering and design, they are easier
than the factory type to fit and very effective. Very slightly more expensive than the
factory option but the quality is outstanding and of course the heat dissipation will be
much better with the vented discs.

The Hydraulics
The brake master cylinder after about 10 years is usually pretty soiled, new seals are
available for most types, but the bores must be in perfect condition. A refurbished dual
circuit or new old stock one is circa £150 - £180. A worthwhile consideration would be to
fit the current type master cylinder with an integral servo this greatly reduces the
amount of physical effort required to apply the brakes. The cost of the parts is around
£300 - £350 they can be fitted to most Morgans though space is tight especially on +8's
and most require some form of heat insulation as the exhaust system passes very close by.
Fitting a servo is not really a job for the inexperienced and dependent upon the model it
takes between 6 and 12 hours and is therefore not a cheap option if you are paying
proffesionals to carry out the work! That said, this conversion makes a huge difference.
The Flexible brake hoses as fitted by the factory are rubber, these expand slightly when
the system is pressurised and it is always a good idea to fit the stainless steel braided
type which firms up the pedal a little. The cost of a set of these is around £75 a little
over double the price of the standard items.
