Absorbs moisture from micro porous hoses or atmosphere.

No, its doesn't get pressurised as its above the actual master cylinder. When a fluid is compressed it produces water so that moisture will be in the brake fluid beyond the piston and seals as its under pressure when the brake pedal is depressed. You would need to sample the fluid from the caliper bleed nipples in which case you might as well bleed the system.

Where do take the test sample ?

Average mileage for everyday car use is 12000 per year. Usually recommended brake fluid change is every 2 years. The brake fluid lack of darkening colour is irrelevant as brake fluid is hygroscopic so as more moisture is absorbed this can vaporise and form bubbles although the fluid in the reservoir may look ok. Change the fluid every 2 yrs for low mileage road use or earlier if heavy track use.

Just got some flat roof rubber repair from B&Q but clean under the arches thoroughly and degrease with white spirit before painting it on.

Morgans are the same as far as being unsuitable for all round year use. When I owned mine in the late 90’s they talked about soggy sill boards where the horse hair padding of the sills below the doors wood absorb water and rot the sill board and frame. An aftermarket company produced a fibreglass moulded replacement. Add to the fact the car leaked like a sieve and water splashed up through the floorboards and was not what you would wish for a price of £23k at the time.

I can recommend the uprated Master Cyl and the use of the Sealy Bleeder Unit It means positive pressure as you close the bleed nipple and you can flush and use a good volume of brake fluid.

I have an ECU from my 1.6 sigma. Updated by Caterham from a 270 S to a 310S if it is of use. It was replaced by Northampton Motor Sport when I upgraded.

Thanks Andrew you are correct. 🙂👍

Flywheels are there to smooth out the pulses of the individual firing of the cylinders. It stores rotational energy to allow a smooth idle. Lightening the flywheel too much can compromise this idle smoothness. Standard production engines tend to have heavier flywheels to give production engines this smoothness as they are are more concerned with driver experience than performance . Flywheels in our sevens can be lighter as we are more tolerant of higher idle rpm which sometimes is required to maintain a smooth idle. My recent lightened flywheel gives an idle speed of approx 1000 so as it moderately lightened does not appear too extreme.

Just checked with Adrian Flux that the work carried out with Northampton Motor Sport didn't affect my insurance premium. They said it was ok and no increase. What a nice company. 👍

No more Chitty Chitty Bang Bang for me 🤣
