hi have you tried bleeding them first? both clutch and brakes also when where the fluids changed? after 3 years they should be drained and new ep90 put in or whatever is recommended for your make and model as over time water can become more evident and not provide proper breaking due to this also have you checked your brake pads and discs are they still all okay, clutch again renew fluids and re bleed as this may solve problem.
only what i would be doing and worth trying/checking hth
