Toyota Yaris Drum Brake Bleed Nipples

Heating could damage the rubber cups and seals in the cylinders, best bet is to replace them, you can splice a new piece of brake line onto the old one but need a double flare tool, In the US you can get them pretty cheap at harbor freight, don't know what's available in the UK though.If line is pretty rusty, may be better to replace it to, you will need a tubing bender so you don't kink the new line when bending it to fit.
