Bear in mind with a 'standard' servo it's got only a tiny percentage of the assistance provided by the electro-hydraulic Teves system that's there already.

Also, if you remove it, you'll have to stick it back on, and make sure it works come MOT time, unless you have a 'friendly' tester...

If you've got a problem with it, it's worth tracing and fixing the fault purely so that your ABS works. I have several guides for testing/diagnosis on the Teves mk2 system - let me know if you'd like a copy.
