I have read a bunch of threads on brakes, but it can get a little confusing. To simplify, I dont want to do the NNBS upgrade at this time. Maybe in a few years. So for now I tow a travel trailer monthly. It stops OK, but I need to replace the pads, and was looking for a recommendation for a pad upgrade that might make a noticeable difference. No dust would be a bonus, but stopping is most important. That being said if there is a part that would make an additional improvement, I would consider. For example - SS lines. Do they really make a difference in stopping, or just a firmer pedal?
