We recently restored a 1275cc-powered 1967 Mini Cooper S, one that was originally equipped with Hydrolastic suspension. What a fantastic design.
Designed by Alex Moulton, this unique suspension system uses hydraulic displacer units filled with water and what is effectively antifreeze. Lines r…
My first car was a Hydrolastic Mini Cooper S 1275 (1293 really, full race SCCA C Sedan car). I kept a gallon of suspension fluid around and raised or lowered the car on a whim by pumping in or out enough fluid to suit my fancy for the day.
The Skill-Lync video is truly terrible, not showing the displacer unit function at all. It includes a cross-section (starting at 1:20), and adds labels, then never shows it working; the description in the audio is even mismatched to the illustration, misidentifying the spring. At one point the later silly graphics even show fluid flowing into front and rear units at the same time, which is not possible because they are simply connected and have no other source of fluid.
To be fair, although there are some good descriptions avaialble online, I wasn't able to find a decent illustration at all.
