Brake master cylinder

[Buster]

My 1976 1500 has a 3/4"  brake master cylinder, but i have seen some 5/8" master cylinders being sold for spitfires , what is the right size ?

5/8" is correct for a Spitfire. 3/4" was fitted to the late GT6 MkIII.
Do you have otherwise standard brakes?
The bigger diameter means you have shorter pedal travel but have to push a bit harder.

As far as I know the rest of the braking system is standard, better look for a new m/c now, does it have a bigger reservoir than the clutch m/c ?

Absolutely... As you can see here http://more-power.co.uk/photos/andys_spitfire/images/170/original.aspx

The originaly master cylinders had metal not plastic reservoirs and the lids could be a pain to get off if they'd been on a while....

Nice Land-Rover, headlights & number-plate in the right places.

;D And steering wheel on the correct side.... although there aren't many who agree over here!!!  :'(

I have the grill, just no means to fasten it... and I really intend finishing it (including painting wheels and wings one day (I may be in the horrible situation of having no vehicles in bits next year   :o so probably next summer!!!)

It's slow, it smokes when it's cold, the heaters mainly for display, it's noisy and hard work to drive, and I love it!!!!  ;)
