Dynamic Friction Company Drum Brake Shoe Set P/N:1903-0612-00
Restore firm, even drum braking on your medium-duty truck with the Dynamic Friction Drum Brake Shoe Set 1901-0612-00 — a premium service shoe set cataloged for both the front and rear drum positions. It drops in as a direct-fit replacement for the 1986-2010 Chevrolet W4500 Tiltmaster, 1995-2009 Chevrolet W3500 Tiltmaster, 1992-2010 GMC W4500 Forward, 1995-2008 GMC W3500 Forward, 1986-2009 and 2011-2018 Isuzu NPR, and 2012-2015 Isuzu Reach; see the Buyer's Guide tab for engine-level fitment.
Each set is field- and lab-tested for reliability. Drum brake shoes are a wear item — signs they may need replacing include reduced braking, grinding or squealing from the drums, and a longer pedal. Replace the shoes on both wheels of an axle together as a matched set for even, balanced braking.
Does this shoe set fit front or rear drums?
This set is cataloged for both the front and rear drum brake positions on the listed applications. Confirm the correct position for your vehicle in the Buyer's Guide tab.
What friction material do these shoes use?
The shoes use a semi-metallic friction material, bonded or riveted to 100% new carbon steel shoes per OE specifications.
Is attachment hardware included?
Attachment hardware such as levers and pins is included where applicable. Check the service procedure to confirm what your specific application needs.
Which vehicles does 1901-0612-00 fit?
It fits medium-duty Chevrolet W3500/W4500 Tiltmaster, GMC W3500/W4500 Forward, Isuzu NPR, and Isuzu Reach models. See the Buyer's Guide tab for full year and engine detail.
Should I replace both sides at once?
Yes — replace the shoes on both wheels of the same axle together as a matched set so braking stays even and balanced.
