Biennial brake fluid change just performed. This time using an inexpensive pressure bleed system provided via Temu. A few issues led to large quantities of brake fluid on the garage floor though when the seal on the bayonet air type union temporarily gave way half way through, this joining pressure vessel holding brake fluid to master cylinder cap adaptor. I initially pumped to 20 psi as recommended by Montegue but found the 10 psi shown in instructions worked almost as well putting less stress on the iffy bayonet. Such fittings are used on air lines and I did wonder how compatible the seal is with DOT 4 fluid.

As a process pressure bleeding is definately the way to go and can be performed single handed. Pleased I had a nice hard pedal after completion.
