* Specific model: Is it a Silverado, Silverado HD, Sierra, or Sierra HD? Even within those models, there are variations.
* Axle: Front or rear brakes will have different bolt sizes.
* Brake type: The size might vary slightly depending on the specific brake system components used (e.g., different manufacturers).
To find the correct size, you must consult your truck's repair manual or a reliable online parts catalog (like AutoZone, Advance Auto Parts, or RockAuto) using your truck's VIN number. This will ensure you get the correct parts for your specific vehicle. Trying to use a generic size could lead to incorrect installation and potential safety hazards.
