Upset and brakeless

Hey guys.ive bought one of the most iconic toyotas ever made,the hilux hipps,or called sfa in south africa.1994 model.i love my vechile,and would not swop it for anything in the world.it goes anywhere,is reliable,and everything ive ever wanted.im so proud of it.the problem is that my local dealership in tableview,cape town,south africa,simply doesnt and cannot supply me with parts for my bakkie.i was looking for a brake master cylinder the past week,and no one could help me.when i phoned toyota mcarthy,they were simply..."your vechile is too old,we dont see them anymore,we cannot help you"....now im driving a bakkie with very little brakes,because the dealership cannot go the extra mile and at least try and help me source the part.ive looked high and low,by every brake,and parts dealer in our area...no one has...what do i do when i cannot find spares by the agency of the guys who made the thing!!!
