Master Cylinder Holes Question

(1/3) > >>

paulbaker1954:
Just rebuilding my Master Cylinder and have a ? I am sure I have seen this ? before somewhere but cant find it !!

There are two holes in the base of the reservoir. One is clear and reatively large the other is my problem. Is it a very small hole or what. I tried poking with the end of a safety pin but hesitant to get more agreesive until I know what it should be like.

Hopefully picture is self explanatory

mickwinf:
yes its a tiny hole and it must be clear to work properly

MrDavo:
I managed to make things worse by breaking the end of a pin in the tiny hole as I tried to clear it of years of hardened gunge.

I thought I needed a new one until a very nice man drilled the hole out with a pillar drill and a tiny bit. The crucial thing then is to make sure there is no swarf sticking out into the master cylinder bore, ripping up your seal with potentially disastrous consequences.

peterengland:
The only thing I found to clear the hole was to snip a bristle from my wire brush and it worked a treat. No pin in the house was small enough
