DeanG Posted September 12, 2022 Share Posted September 12, 2022 Hello I'm currently getting my 1990 seven back on the road after being laid up for a number of years. I've found that the master cylinder reservoir has cracked does anyone know where the best place to get a replacement reservoir or if not a new master cylinder the marking on it is Locheed .70 3211.420 thank you in advance Dean Link to comment Share on other sites More sharing options...
ECR Posted September 13, 2022 Share Posted September 13, 2022 On my 1990 car the reservoir is integral with the cylinder. Is your reservoir separate?id speak to Redline... Link to comment Share on other sites More sharing options...

DeanG Posted September 13, 2022 Author Share Posted September 13, 2022 The reservoir is held on with 2 screws but im not sure if you can get it separately or if you need a whole master cylinder I'll try redline for advice thank you Link to comment Share on other sites More sharing options...
Youds7 Posted September 13, 2022 Share Posted September 13, 2022 I've seen reservoirs in the Demon Tweaks catalogue, no idea if they would fit your MC. Link to comment Share on other sites More sharing options...
Mrb00ns Posted September 13, 2022 Share Posted September 13, 2022 I have just removed the standard master cylinder from my car (replaced with updated) so have it spare and would be willing to sell if you are interested Dean? It's from an 18mth old car. Link to comment Share on other sites More sharing options...
rkeywood Posted September 15, 2022 Share Posted September 15, 2022 Hopefully Chris will sort you out but if not the check the number stamped on the body, it's usually 3211.426. That's the body only and there should be a metal tab sandwiched between the reservoir and body with the master cylinder number, usually 4222-404. The cylinder was used on a bunch of Vauxhalls (eg Viva HC Firenza) and other '80s cars. Try Northwest or google should find some options.I've not seen the reservoir sold separately for a long while but that's 3251-789 and was used on quite few other bodies as well. There's also a couple of larger capacity variants of the reservoir that were used on the 3211 and other bodies that will fit.Lockheed catalogues can be found here Lockheed catalogues The usually Caterham period arrangement is Illustration 171 on Page 2497Hope that helps Link to comment Share on other sites More sharing options...

DeanG Posted September 18, 2022 Author Share Posted September 18, 2022 Not sure if this would fit my car as yours is a lot newer than mine but thanks for the offer. Dean Link to comment Share on other sites More sharing options...
OldAndrewE Posted September 18, 2022 Share Posted September 18, 2022 I presume you are talking about the wedge shaped reservoir. I may have one from the M/C I had to replace on mine. Where are you based? Link to comment Share on other sites More sharing options...
