Nigel Riches Posted December 29, 2015 Share Posted December 29, 2015 Anyone know which rear brake cylinders where installed to marina or ital rear assemblies, fitted to a 1982 S3.I have 3 different sizes found from searching t'internet, 15.75mm / 0.625", 17.78mm / 0.7" and 19.05mm / 0.75". Short of physically removing and measuring one I hope someone knowledgeable on these matters may know the answer.Thanks for any assistance. Nigel.

Ivaan Posted December 30, 2015 Share Posted December 30, 2015 How does you current brake set up feel? Do the fronts lock a long way before the rears? Do the rear drums get hot?My car ( live axle Ital ) was hugely over braked on the front, the rears where staying stone cold and not aiding any of the braking effort. Increasing the size of the rear slave cylinders helped the balance to a point.If you're happy with the set up, I'd remove one and take it to the suppliers. There's plenty of factor outlets about that can supply the cylinders.The larger sizes where used on the Estate version of the Ital.The best solution to poor brake balance is a rear disc conversion. Ask for details if you're interested.Clive Link to comment Share on other sites More sharing options...

Nigel Riches Posted January 2, 2016 Author Share Posted January 2, 2016 Thanks for the replies.Think I'll get one off, as I have the master cylinder off for a leaking seal, so not to have to bleed the system twice.Regards, Nigel. Link to comment Share on other sites More sharing options...
