I like some others have put up posts about brake problems on the Jazz. My Brother lives in Canada and has a Jaguar XJS. He has experienced brake problems with deteriorating seals in the braking system. The failing seals were blamed on incompatability with Girling Brake Fluid, it was recommended that He use USA made brake fluid!!!! He has just sent me an E mail on Brake Fluid. Using Google put in 'Girling brake fluid'. There is an article on brake fluids headed 'Tech article, Brake fluid for classic British cars'. It is applicable to us as Jazz owners because it explains such things as why it is imperative to change the brake fluid as per manufacturers service schedule. This article is NOT for the faint hearted BUT if you are interested, plod on as it explains an awful lot about brake fluid/ brake fade/ failing seals and allied problems. It contains an awful lot of technical information but to some one like me that is on the borderline between amateur and professional mechanic, it explains a lot. Why do we have clear plastic reservoirs on the master cylinder? It is to obviate the necessity to remove the cap. Every time the cap on the reservoir is removed water is absorbed! It even goes as far as to suggesting checking the seal on the top of the reservoir, that's how important it is to keep it all sealed tight. Copper brake lines, all the rage in days gone by BUT there is chemical reaction in the pipes. It is far too much to trivialize by trying to precis it BUT it is well worth reading. Even the experts might find some interest. Good reading.
