The very first entry (June ’21) in my workshop diary for the Hornet was to replace the cups and boots on the brake slave cylinders as they were leaking and at the same time I inserted modern oil seals on the rear axles as the rear brakes were covered in oil. As it happened this was a complete waste of time as there were parts missing (parts 6 & 8) so the brakes continued to leak

Times have moved on so now you can use the following instead of the the spring and the two missing bottle caps. Also I have found that the first series of Chevy Corvette rear wheel cylinders have the same diameter and piston arrangement plus they are very cheap I bought some ($17 each for a complete wheel cylinder) and ratted the springs, cups, boots and pistons.

Also the modern oil seals placed in the rear axle tubes had been running on what I realised later were wonky axles so they still leaked and destroyed another set of brake shoes. Luckily Hornet’s very close relative MG has a community that had a solution.
What were originally a weird castellated nut (first pic) that held the rear hub on became a hex nut (second pic) with an oil seal in the centre and the now new axles and hubs (again MG) had a stainless steel sleeve (marked blue) epoxied in place for the seal to run on.



So after about a year the brakes and the back axle don’t leak but the brakes are still crap at their actual job of stopping. To be continued.
