I'd prefer to retain braking ability when going down a steep hill with 2 wheels on mud and the other 2 are on a dry asphalt surface and a **** in a 4WD hurtling up the road without any intention of pulling over.Well, if it works as intended, t should mean that one doesn't have the 'ability' to brake so hard that the car skids. Would you prefer to retain your ability to make the car skid?
