mag brakes

hi lads ,took my mag elite apart and found that the mag brakes had rusted over .when i took them out the rust had eaten 1 nothing but rust left ,any ideas how to fix it or how to stoping it happening again

try dan in the halfway, he might have an old one with the bits you need, or else try murrays in town, i handed my mag elite in when it was broke and they charged me a whopping €6.50 to repair and service it
