Got all the brake lines and other brake accessories replaced including the brake booster assembly (had to change 3xboosters in order to get the right combo).
One alteration we did was to add a vacuum assisted clutch Master Cylinder. The brake booster assembly of a Vitz was used for the purpose. The alternation was worth as it improved the driving comfort of the vehicle (As the vehicle is to be used by my father occasionally).
Power steering box from a toyota Prado was also added which was bolt on swap.
