I had a brake job done today, both front and rear, on my 2004 Impreza
2.5 TS Wagon, almost 60,000 miles. This was done at an independent garage. While they did not replace the calipers, they replaced the caliper sliders at $15 each.Was this really necessary? Is this something that is going to prevent problems in the future, or was I just nickle-and-dimed for $60?
