Brakes - complete renewal of pads,shoes, cylinders the lot. I can see how the pads and shoes would possibly have hardened but can rest generally be saved? Brake lines I guess would corrode and need replacing.
Exhaust - I guess if its rusted its rusted.
Tyres - Cracked etc. Im guessing these are no good or are cracked tyres still ok for mot?
Mounts - I guess the rubber would perish?
