Description
When your brakes start feeling spongy or you have to pump the pedal to get them to grab, it’s usually this brake actuator assembly that’s giving you trouble. This critical component converts hydraulic pressure from your master cylinder into the mechanical force that actually stops your tractor. Without it working properly, you’re looking at poor braking performance or even complete brake failure—definitely not something you want when you’re hauling a loaded wagon down a hill or trying to stop quick on the road.
What You’re Getting
- Complete actuator assembly that mounts directly in place of your worn unit
- Precision-machined components that maintain consistent hydraulic pressure
- Heavy-duty seals designed to handle thousands of brake cycles without leaking
- Works with standard brake hydraulic fluid for reliable operation
- Factory-quality construction built to withstand the demands of farm use
Built for Real Farm Work
This actuator fits Ford New Holland 40 series tractors like the 5640, 6640, 7740, 7840, 8240, and 8340, plus the TS series including TS90, TS100, TS110, and TS115 models. These are serious work tractors that spend their days pulling heavy implements, hauling loaded trailers, and working challenging terrain where reliable brakes aren’t just convenient—they’re essential for safety.
Made to Last
Farm tractors put brake components through the wringer with constant pressure cycles, temperature extremes, and exposure to dust and moisture. This actuator assembly features robust internal seals that resist deterioration from brake fluid and maintain their sealing properties even after years of service. The precision-machined bore ensures smooth operation and prevents the internal leakage that causes brake fade.
Good to Know
This is a direct replacement that bolts right where your old actuator was mounted. The spring component (part 1886562) and slave cylinder (42223) are available separately if you need those pieces. When installing, it’s a good idea to flush your brake system with fresh fluid since you’ll be opening the lines anyway. Always bleed the system completely after installation to ensure proper brake feel.
