We are doing a full brake rebuild on the 65 Valiant convertible. Front 9 inch brakes. We received new Wagner brake shoes and they are different than the ones we took off. 2 of the 4 shoes in the box look like thye only have padding on 3/4 of the shoe. The other 2 have full coverage. The old shoes were fully covered on all of them. The car will continue to be really low mileage, and it never had a braking distance issue in the past. Wondering if these shoes were mis-manufactured and I should persue getting another set (delaying the project) or just not worry about it. They fit otherwise.
