If you want a robust, direct-replacement air supply knob set for your MV-3 dash valve that restores critical safety controls, choose Torque Parking Brake &; if you need a targeted fix to restore a missing fastener on your Curt Echo brake controller strap, choose splash n color SplashNColor Replacement Strap. These two items solve entirely different problems in the towing and heavy vehicle ecosystem, yet both are essential when specific components fail or wear out during the rainy season.
• Torque Parking Brake &: Offers a high-quality, solid plastic replacement for Bendix knobs with a precise 5/8" thread, making it ideal for restoring dashboard functionality; however, it is strictly limited to threaded MV-3 type valves and does not fit other valve styles.
• splash n color SplashNColor Replacement Strap: Provides a simple, cost-effective solution to replace a lost button on a brake controller retaining strap without needing a whole new assembly; its trade-off is that it is a single small part requiring you to already own the correct strap and controller hardware.
• Who each pick is for: Torque fits the driver who needs to repair their vehicle's primary air system controls immediately, while splash n color fits the trailer owner who lost a tiny button but wants to keep their existing brake controller setup intact.
This product is designed specifically for the operator of a medium-duty truck or trailer equipped with an MV-3 push-pull dash valve. The core function here is restoration. When the original yellow parking brake knob or red air supply knob from brands like Bendix fails, wears down, or simply falls off, this Torque set steps in as a direct replacement. The design philosophy is straightforward: durability and exact fitment. This low weight ensures they do not add unnecessary bulk to the dashboard, yet they are built to be durable enough for daily use.
The most critical specification for anyone considering this purchase is the thread size. The product explicitly states a 5/8" thread, which is the standard for mounting onto MV-3 type dash valves to moderate pressure. If your valve has this specific threading, installation is described as direct and easy. You do not need to modify the valve or drill new holes; the unit count is one set, replacing the specific Bendix part numbers 298817 (Red Air Supply) and 298818 (Yellow Parking Brake). This makes it a perfect match for fleet managers or individual owners looking to maintain safety compliance without waiting for obscure OEM parts.

However, this product is not a universal fix. It is engineered for a very specific interface. If your vehicle uses a different valve style or a non-threaded attachment method, this kit will not work. Furthermore, while the material is described as high-quality plastic, it is not a metal upgrade; it is a functional replacement designed to look and feel like the original factory parts. It is best suited for drivers who value the ability to quickly swap out worn controls to ensure their air braking system remains operational before hitting the road, especially during the rainy season when visibility is poor and reliable dashboard feedback is non-negotiable.
In stark contrast to the mechanical complexity of a brake valve knob, this item addresses a common frustration in the towing community: the loss of a tiny, easily misplaced component. The splash n color Replacement Strap Button is designed exclusively for users of the Curt Echo brake controller. The problem it solves is immediate and specific. If you perform a pre-trip check and discover that the button holding your brake controller strap in place is missing, you might panic and think you need to buy an entire new strap assembly. This product tells you otherwise. It replaces only the fastening part that went missing, allowing you to keep using your existing brake controller and strap.
The utility here lies in its targeted nature. It is a hardware fix for a hardware gap. Whether you are hauling a trailer across town for a local job or preparing for a long-distance road trip, losing that one small button renders the strap useless because the controller can no longer be secured. This replacement part fills that exact void. It is compatible with your existing setup, meaning you bring your own brake controller and strap assembly, and this plastic piece does the final securing job.
The physical characteristics support this role. The packaging indicates that no additional hardware is included; it is purely the button itself. This product is for the practical tow owner who understands that replacing a whole assembly is wasteful when a single fastener is gone. It is particularly useful during the rainy season, where a loose brake controller could slide around the cab floor, creating a hazard. Securing that strap back into place with this button ensures the controller stays put, regardless of the weather conditions outside.

I would choose the Torque Parking Brake & if I were facing a failure in my truck's air braking system because the stakes are higher; losing the ability to clearly identify or engage the parking brake and air supply is a major safety risk. However, if I were a trailer owner dealing with a missing button on my Curt Echo controller, I would grab the splash n color strap replacement immediately. It is the smarter financial and logistical choice to save time and money by fixing the root cause rather than replacing the whole system. For the rainy season, having a secure, functioning brake controller is vital, and this small button ensures your gear stays exactly where it belongs when the roads get slick.
