The shoes were slightly different than the ones I took off. They are the same length but like you noticed, the new secondary shoe has more friction material than the one I took off. There is a a primary and secondary shoe in with the new ones I bought but the secondary shoe has more material than the old one. I don't think this will pose a problem... although i am not 100 percent sure. I ordered new parking brake cables since mine are rusted and I am unable to adjust them, hopefully that will fix the problem.

Do you think that the secondary shoe being different then the one I took off will cause and issues?
