Brake Thread Sealant?

[cult45]

NOS brake master works great but is leaking, both at the cups and the senders [though could be leaking from the cups onto the senders]. I didn't use any thread sealant during assembly. Should one have..? And if so, what?

At the bottom of reservoirs is copper crush washer and hollow bolt. Take everything apart ,clean bits, and reassemble to sqeeze plastic housing just a bit. If yer carefull , you shouldn't have to bleed brakes.

You might also be leaking from rear seal where it abuts the booster. If that's so, maybe time for a non ABS FJ80 MC replacement.
