Does anyone know the tool / size needs to remove the brakes from a 2000 focus ZX3. (it looks like an allen wrench maybe 7mm?) but im wondering if it's a dealer only tool. I needed the info before i went out and bought a 7mm wrench. (the kit i have goes from 6 - 8 - 10. it's larger than 6 and smaller than 8. but if it's a dealer only tool then it might be a 7.xx ? who knows. thanks for the info.
