To celebrate the victory I treated the car to a full set of Goodridge stainless-steel brake-hoses, front and rear, as I figured if one is beginning to swell then they could all do with replacing. The set cost me £93 from CAM Motorsport on eBay, which was slightly dearer than average, but they were the only stockist who could guarantee them in time for my re-test. For the price you also get two 1L cans of Super Blue Racing Brake-Fluid, worth about £30, which has a higher boiling-point than normal, though I doubt I'll ever get to try that out, but hey at least I had some fluid.
Oh, and I also bought the best dang Bosch wiper-blades I could find!
