Hello, welcome and thank you for using Justanswer.
What did really happen with your brakes ,did the pedal went down to the floor?
Is the pedal hard, when you stepping on it ?
Is it soft and low ?
Let me know ,i can not help on the cost because i am not from South Africa.
If this is really what you need ,you can always go to an independent shop ,they are definitely cheaper (labor) than the dealer.
let me know.
Let me know what you have.
