sorry yet another question, hopefully this might help someone else too in the long run
picture below is of my brake master cylinder, for a 1975 2.7 Carera (no servo)

question is whether it needs replacing as the 2 upper rubber conectors are somewhat perished, looking a little hardened and a few cracks in them both
New cylinder is only around £100, but can one buy service kits for these things ?
thanks
jonathan
