Keep your rear drum brakes working quietly and consistently with the Dynamic Friction Company Drum Brake Hardware Kit (MPN 370-37003, also written 37037003). This kit replaces the worn springs, retainers, and small hardware behind the drum on the 2004-2008 Chevrolet Colorado and 2004-2008 GMC Canyon, plus the 2007-2008 Isuzu i-290, 2006 Isuzu i-280, 2006 Isuzu i-350, and 2007-2008 Isuzu i-370 — a direct-fit set for the listed rear applications.
These small components position the brake shoes, return them after each stop, and hold everything in place. Fresh hardware is recommended whenever you replace shoes so the brake operates the way it should.
Sold as a rear axle kit, not per side, so you have the pieces for both sides of the axle. See the Buyer's Guide tab for the full engine-level fitment.
What does this hardware kit include?
It supplies the springs, retainers, and small hardware that position and return the rear brake shoes. It is sold as a rear axle kit, not per side, covering both wheels on the axle.
Does this fit my vehicle?
It's a direct-fit rear kit for the 2004-2008 Chevrolet Colorado and GMC Canyon, plus the 2006 Isuzu i-280 and i-350 and the 2007-2008 Isuzu i-290 and i-370. Check the Buyer's Guide tab to confirm your exact vehicle.
When should I replace the drum brake hardware?
Replacing this hardware is recommended whenever you install new brake shoes, since worn springs and retainers can cause noise, drag, or uneven shoe wear.
Do I need one kit or two?
One kit. It is sold as an axle kit, not per side, so it contains the hardware for both rear wheels.
Can worn hardware cause brake noise?
Yes. Weak or worn springs and retainers can let the shoes vibrate or drag, which may produce noise. If failed hardware is the cause, this kit replaces it.
