Aurelia B20 S3 brake master cylinder

[williamcorke]

I removed the M/C from the S3 this weekend and dismantled it.

The bore looks good, but I'm not sure what rebuild kit I should buy for it.

Photos below show:

1. cylinder and inner assembly, in order
2. As 1 but from a different angle
3. Tav for S1 Aurelia M/C
4. M/C diagram found on this forum for an Augusta - this seems similar to mine.

What's confusing me is that my M/C is a much simpler design than the one show in the parts book.

The internal diameter of mine is 1 inch. The hole at the back end (opposite end to the pushrod) is concentric to be bore: I've seen a lot of photos of M/Cs that have an offset outlet there. I'm sure it was working on the car at some point - there was still fluid right through the system and everything seems to be in as good condition as you could hope for given fiftysome years off the road.

Any thoughts and advice welcomed.

Looks like you have a Lockheed master cylinder on your car. If you give it a good wire brush, you might find the Lockheed part number on the r/h side, like 993.

Being not familiar with Aurelias, I believe the brake system was made by SABIF. M/C can be bought from Cavalitto and Amadei Ricambi and others. I am sure, Aurelia owners in this forum will know more.

Karl is correct. s.2 M/C was by Sabif, and yes, Cavalitto is your man. Replace - as we've never had any luck with sleeving, although everyone says their guy is the best.....
