Built for Real Farm Work
This kit restores braking power to John Deere 40 Series tractors—the 1640, 2040, 2140, 3040, 3140, and 3640 models that have been the backbone of farms for decades.

Made to Last
Farm brake systems deal with dust, moisture, and temperature swings that can destroy inferior seals quickly. These replacement seals are manufactured to handle the demands of agricultural work, using materials that resist brake fluid contamination and maintain their flexibility through years of service.
Installation Notes
Master cylinder rebuilding requires clean working conditions—any contamination will destroy new seals quickly. Remove all old fluid and thoroughly clean the cylinder bore before installing new seals. After rebuilding, bleed the brake system completely to remove air bubbles that cause spongy pedal feel.
