Do a search on (Roadmaster Invisibrake Problems) and you may change your mind about the Invisibrake. I had it on my 98 Honda Accord worked great tell it rained and the brakes wanted to lockup. The little red light keep coming on, while others have lost brake pad and rotors. It may come on when just driving if it is raining, just the luck of the draw if you have problems. I went with the SMI Air Force One on my Ford Edge.
