[Fot] Leaky brake master cylinder resevoir

[sherry robyn]

On my 74 TR6, I have a leak between the master cylinder and its resevoir. It was 
pretty clean but I cleaned it all spotless and used new rubbers between the m/c 
and its resevoir. It still leaks. Has anyone been here on this? I'm wondering if 
I should sand down the 4 attachment points so as to get more pressure on the 
rubbers or is a new resevoir my best option? Thanks for any assistance on this.
