I'd try and keep the servo on if you can... but it does sound like it isn't working to me!! Have you tested it to see if it is working? With the engine off, pump the brake pedal half a dozen times to release any vacuum in the system. Next press and hold the brake pedal and start the engine... if the servo is working, the pedal will press down as the vacuum builds. If it doesn't, then you need to check all of the flexible hoses between the engine and the servo, and also the steel tube that runs front to back. If they are ok, then likely as not, the diaphragm in the servo has perished, and the servo needs replacing!! You can use the cheaper Brazilian servo, you just need to change the stud pattern in the mounting plate slightly!!
