i have used silicone fluid in my 60 mga for the last 20 yrs with no problems. i just put it in and used it to flush the system, which was the instruction in my restoration handbook. yes the brakes are a little spongy but i was warned of that. btw corvettes should not use, i don't know why but that ws a warning i read somewhere. i used a bleeder i got from moss motors that uses the air in the tires for pressure.
