MGM Brakes Mgm CS20L S-Cam Brake 60-Count Pack - 1621901X

Early signs of failing spring brake chambers often go unnoticed without visual inspection. When performing routine maintenance on your semi-truck or other commercial vehicle, you may want to check to see if the brake chamber rod is bent; isn't fully retracting or chamber and slack adjusters are out of adjustment. It could be time for a replacement. After all, brake chambers should be replaced every two-five years.
