BRK4591SF
This is a brake shoe kit for heavy-duty trailer air brake systems. It replaces the shoes on one wheel of a Dexter-style 12.25-inch diameter by 7.5-inch wide S-cam drum brake, commonly used on 23,000-lb trailer axles. The kit includes two new shoes pre-lined with friction material and the mounting hardware needed for installation. You would replace it when shoes are worn down, contaminated, or cracked to restore safe stopping power.
Designed for 23K GAWR axles. Verify your brake dimensions (12.25 in. drum, 7.5 in. wide shoe) and closed/closed S-cam style before ordering. The shoes may fit multiple OEM axles that share the FMSI 4591SF profile.
