I used to find standard Brembo discs from GSF and Ferodo DS2500 or DS2000 pads a good combination when I had the standard 239mm discs.
Replace the brake fluid with a good quality fluid (I use Motul RBF600, it's not particularly expensive and I've never managed to overheat it). Service the rear drums replacing any worn parts, this needs doing regularly, if the rear brakes are poorly setup then it affects the fronts too.
