I know a lot of people will disagree with me but why change them. I know the advantages of disc brakes still I believe unless you are going put some monster engine in the Gremlin or going to race it the drum brakes will do fine. I know for the first 10 years I drove a car all we had were drum brakes. I think the first car I had with disc brakes was my 77 Gremlin. The only problems I remember having were if they got wet or if they were glazed they would fade other than that they worked fine. If it were mine and all I was using the Gremlin for was to take pleasure rides to the park and going to car shows I would save my time, effort, and money and use it for something else on the car. Just my thought. Good Gremling. [Non-text portions of this message have been removed]
