Frequently Asked Questions About International PayStar 5000 Brake Parts & Acc.

Will these brake parts fit my specific year PayStar 5000, and are they DOT compliant?

Most brake components listed are designed to fit PayStar 5000 models from 2007-2016, but specific compatibility varies by part. Always verify your truck's VIN and model year before ordering. All our brake parts meet or exceed DOT FMVSS 121 standards for commercial vehicles. Check individual product descriptions for exact fitment details, as some components may have variations based on axle configuration (single vs. tandem) and GVWR ratings.

What's the difference between OEM and aftermarket brake pads, and which should I choose?

OEM brake pads typically use the exact compound and backing plate specifications as factory-installed parts, while quality aftermarket options often provide improved stopping power and longer wear life at a lower cost. For severe-duty applications like construction or heavy hauling, we recommend ceramic or semi-metallic aftermarket pads rated for 23,000-26,000 lb axles. Standard highway use can benefit from organic compounds that produce less dust and rotor wear.

Do I need special tools to install these brake chambers and slack adjusters?

Yes, proper installation requires specific tools including a cage bolt tool for spring brake chambers, a slack adjuster wrench (typically 9/16"), and torque wrenches capable of 450-500 ft-lbs for wheel bearing adjustments. Air brake system work also requires proper lockout/tagout procedures and should be performed by certified technicians. Many customers report that pre-adjusted automatic slack adjusters save significant installation time compared to manual units.

How do I know when to replace brake drums versus just turning them?

PayStar 5000 brake drums should be replaced when they exceed the maximum diameter stamped on the drum (typically 16.620" for 16.5" x 7" drums). Most drums can be turned 0.060" to 0.080" before reaching discard diameter. Signs requiring immediate replacement include heat cracks longer than 1.5", blue discoloration from overheating, or out-of-round conditions exceeding 0.015". Always measure with a drum gauge and replace drums in axle sets to maintain balanced braking.

Are brake hoses and gladhand seals universal, or do I need PayStar-specific parts?

While gladhand seals and service line hoses follow SAE J1402 standards and are generally universal, chassis-specific brake hoses vary by wheelbase and suspension type. PayStar 5000s with Hendrickson suspensions require different hose lengths than those with Chalmers setups. When ordering, provide your truck's wheelbase measurement and note whether you have air ride or spring suspension. We recommend replacing rubber hoses every 5-7 years regardless of appearance due to internal deterioration.
