    S2a confusion

    Hey there brains trust

    Newby here. Just scored myself a old S2a Ute and in the process of stripping down and replacing all the cactus bits. I am just confused with if this is actually a S2A the bulkhead label says S2a but on further inspection of RH front spring hanger it has stamping of Y1976 F1. See attachment. Wouldn’t 1976 make it a S3?

    Just want to confirm model before ordering parts.

    Also I need new brake master cylinder, originally it has a single line with no booster. Is it possible to fit dual line cylinder with booster? And if so are there any tricks or issues in doing it.

    Thanks in advance for any pearls of wisdom

    Cheers

    The number looks like it has probably been issued by the relevant authority as a chassis number replacement. The 253 prefix on the tally plate indicates it is a LWB 2A that came to Aus as CKD. The G suffix indicates it is a late 2A, 69-71 (ish).

    As above for what it is. Check the LH rear back spring hanger for the original chassis number and confirm it is the same as the plate on the firewall.

    It is possible to fit dual circuit boosted brakes, but it is not a simple matter of replacing the master cylinder. The entire brake pedal assembly and a fair bit of piping needs to be replaced as well. in addition the panel from the footwell to the top of the mudguarf needs to be replaced by one from an S3, and a new bracket to attach it to the mudguard fabricated and welded or rivetted in place.

    Personally I would not bother. In good condition the unboosted brakes perform quite well for the performance available. A single circuit booster is quite easy to fit if you feel pedal pressures are too high. I have been driving vehicles with single circuit brakes for about sixty years, and have never had brake failure. just a matter of regular checks for signs of fluid leaks and fix them.

    Thanks I’ll check LH rear
