Harley Davidson brake pads have wear indicator marks in the brake pad friction material, but the marks are sometimes hard to see with the pads installed on the motorcycle. By removing the brake pads from the motorcycle you can easily see and measure the brake pad wear. The minimum brake pad friction material thickness for the 2008 Harley Davidson Road Glide for both the front and rear brakes is .016". The brake pads can be measured using a set of calipers.
