With the problems we experienced in bleeding the rear drum brakes on the Bugeye, we decided to go ahead and upgrade to the later Sprite/Midget rear brakes with the dual action cylinders. My Dad was able to source all the parts from Gerard Chateauvieux (formerly Gerard’s Garage). Gerard didn’t know the exact year of the donor car, but said it was a 1968-72 model. The parts arrived and look great. My Dad built up the rear assemblies and we will install and bleed the lines once again when I can get the car to his garage.
MiniMania has a great instructional video on how to put the brakes assemblies together, but Dad made a video himself: https://vimeo.com/666405518/a1d0cbd91b
