You still havent really explained why you did not call the garage as soon as you got home to explain the brake problem and see what they would do about it .....they would have called out and either sorted it there and then or recovered the vehicle to their place . .
As for your comment about your Toyota having "real brakes and not anti-lock" it's nothing to do with anti-lock .Brake circuits are of dual setup,unless your car is very old....I believe the diagonally opposite wheels are on one circuit and the other two on another circuit..both fed by their own fluid so if there is a fault in one pair the others will work ( to a degree) .I might be wrong there ....it could be frontwheels and back wheels but I don't think so .
