Ah yes, those seals. I believe the proper procedure is to mix peanut butter (smooth, not chunky), marmite, and Vegemite in equal proportions, expose the mixture to X Rad of 122 keV gamma radiation (where X is your longitude in degrees), and then apply the mixture to the two halves of the caliper. They will never leak/separate/function again.
If that doesn't inspire confidence*, try the T3 Sport/Touring
