Rear wheel brake cylinders are a pain. I am still battling my tr3 brakes. The wheel cylinders I ordered leak. Granted I bought the cheapies and “now I want to know if the .7 Girlings” that BPNW offer for 40.00 will work on a tr3. They should. I think they are for tr4a and up, but won’t they inter change as a pair? They offer the ¾ bore as OE, but they are 80.00 and I am not sure if they are new or NOS.
