If your housing is old or worn, your braking and shifting will definately suffer. Replacing housing and putting on new brakes is one of the best things you can do to tune up your bike and make sure it is safe.
Replacing housing is a difficult job and takes a lot of time. I spent several hours doing it with a great mechanic. O.k., he did it and I just watched. I would recommend having a trained mechanic replace your housing as it is difficult and if not properly done, then you are wasting your time. Small details make a difference, like filing the ends of the housing before capping among other things.
Anyone who is having trouble braking and or shifting should look into this type of treatment.
