Hope I'm not swearing in church here, but the simplicity reminds me very much of the Citroen CX's setup. Two slim forged steel arms and an all aluminium 'hub/4-pot calliper' combo with inboard suspension.
I wouldn't use Hammerite anywhere. It becomes too brittle and chips off, or at least it did last time I used it about twenty years ago. In respect of the discs - I would sand off the rusty deposits, use rust converter if it floats your boat, but otherwise etch prime and finish in satin black. Then it looks the business. All this can be done on the car. And at the same time tidy up the track rods and anything else looking worse for wear. If you neglect it - it will only deteriotate over time to a point at which it can't be saved. Discs need tlc every year or so.
thanks...especially for the heads up on the Hammerite. I think I'll live with the slightly rough inner wheels.
The only 2 bits of rust are the pressed metal cap on the top of the suspension upright and the disk. The metal cap I've cleaned, treated and will paint it silver. It will be the same at the back.
The disk I've treated but will leave unpainted, very little shows at the front.
At the rear it is another matter, the disk centre needs painting black.
No, I am pretty sure the CX's swivel had regular but rather oversized ball joints. The upper inner bearings were tapered roller bearings and the lower were some kind of 'plastic' material. Very stiff rigid and kept the wheels in place rather well.
With the front near side done it was time to see what needed doing on the rear hub.
Step one was to remove the wheel: this is what greeted me. A rusty dirty disk centre, visible through the wheel, was exposed: work to be done. The photo was taken part way through masking up, after rubbing down with wire wool.
Two brake callipers? Yes, the front one is the handbrake, clearly showing the “Brembo” label on the pad backing. The after calliper is a 2 pot unit by AP Racing, to match the 6 pot ones at the front.
I’d been asked what sort of wheel nuts were used on the Aero Plus 8. This is what came with the car, very neat stainless steel nuts, they need a polish but look good.
The next photo is taken under the wing, looking aft. It is nice to see the inside of the wheel arch is wood and the construction is very much traditional Morgan. I need to look at fitting some stone protection, as described by DW and others. But that is for another day.
This photo shows the rear suspension elements: not quite as neat as at the front, but just as well engineered.
After cleaning up the hub and calliper I masked off the area where the wheel sat and then painted the rest with black Hammerite “Smooth” finish, it looks good!
Whilst the paint was drying I cleaned and polished the wheel and cleaned and waxed the callipers. I need to get some yellow paint to highlight the “AP Racing” logo, so as to match the front!
Remounting the wheel I was very pleased with the result!
