Brake shoes wear out gradually — so gradually that many fleets miss the warning signs. Knowing when to replace them prevents damage to drums and, more importantly, keeps your drivers safe.

Signs your brake shoes need replacement

• Metal-to-metal grinding noise — the lining is completely worn.
• Reduced braking performance — longer stopping distance or a low pedal.
• Visible wear — lining thickness below the recommended minimum (check your manual).
• Uneven wear — one shoe worn more than others, indicating an adjustment or hardware issue.

What to check during replacement

• Brake drum condition — scored or oval drums should be machined or replaced.
• Return springs, adjusters and hold-down hardware — replace worn parts while the hub is open.
• Wheel seals — a leaking seal contaminates the lining and shortens shoe life.

Choose the right shoe

Match the OEM number on your old shoe, and confirm the lining material suits your application (standard, heavy-duty or low-noise). Reputable suppliers like UIB Truck Parts can supply popular models such as the 4709 brake shoe with matching OE specifications and custom lining options.
