Hey John, thanks for reaching out. The brake shoe lining on a 3,500 lb axle brake assembly should be like 0.18" when brand new. Dexter recommends replacing the shoes when they get down to about 0.0625 or 1/16". Let me know if you need anything else.

Hey John, how did things go checking the brake lining thickness on your 3,500 lb Dexter axle? Your update could make it easier for the next person working on the same brakes.
