Recently, we wrote about converting manual to power brakes whether your car originally came from the factory with drum or disc brakes. We received several follow up questions from people with drum brakes looking to upgrade to better braking - but trying hard to stay on a budget. Since the hardware at the wheels and brake lines can remain untouched after converting to a power assisted pedal, we were asked, "Can I just add a booster and new master cylinder to my car?" Essentially the questioners were asking whether the booster master conversion kit or the complete brake conversion kit was their best solution.
Of course, like the answer to a lot of questions, it depends!
