Description
When your brakes start feeling spongy or you’re having to pump the pedal just to get your David Brown to stop, it’s time to replace that brake slave cylinder. This Carlisle cylinder is built specifically for LHM mineral oil brake systems—the green fluid your David Brown uses instead of regular brake fluid. Don’t gamble with weak brakes when you’re hauling loaded grain carts down steep hills or navigating busy farm roads.
What You’re Getting
- Designed specifically for LHM mineral oil systems—won’t fail like regular brake cylinders
- Carlisle quality construction that handles the constant pressure and movement
- Precision-machined bore provides smooth operation and consistent brake feel
- Direct replacement for worn or leaking cylinders with no modifications needed
Built for Real Farm Work
Your David Brown 1490, 1494, 1594, or 1690 tractors are workhorses that handle everything from heavy tillage to road transport with loaded wagons. These 90-160 horsepower machines can build serious momentum, especially when pulling equipment or climbing out of fields onto highways. Whether you’re running a 1490 for general farm work or pushing a 1690 hard through spring planting, reliable brakes aren’t optional when safety matters.
Made to Last
This Carlisle cylinder features internal seals specifically formulated for mineral oil compatibility—regular DOT brake fluid seals would deteriorate quickly and leave you with no brakes. The precision-machined cylinder bore resists wear and provides smooth piston movement even after thousands of brake applications. Heavy-duty construction handles the pressure spikes that happen during emergency stops.
Good to Know
Before installation, make absolutely sure your system uses LHM mineral oil—mixing fluids will destroy seals throughout the entire brake system. Bench bleed the new cylinder before installing to get all the air out. After installation, bleed the whole system thoroughly because any trapped air means poor braking. Keep repair kit 4745 handy for future maintenance, and remember that good brakes can mean the difference between a close call and a serious accident.
