The kit includes two shoes (enough for one wheel) and the necessary hardware, providing everything needed to replace the friction material and restore proper braking performance on a single wheel end. You typically replace these shoes when the lining wears down to its minimum thickness, which can lead to reduced braking power, metal-on-metal contact, or failing a DOT inspection. This specific Haldex kit uses a high-grade 23,000 lb GAWR lining, making it appropriate for trailer axles rated for that weight.
