Restore full hydraulic braking assistance and maximum OSHA safety compliance to your heavy-duty Clark forklift with this premium Replacement Brake Hydrovac Repair Kit (Part # 991878). Engineered specifically to rebuild the hydraulic brake boosters on Clark C500 and Y-series internal combustion lifts, this comprehensive kit includes all the heavy-duty diaphragms, seals, springs, and hardware required for a complete, leak-free overhaul.
A failing hydrovac booster results in a dangerously stiff brake pedal, severely increased stopping distances, or total loss of braking assist under heavy industrial payloads. This direct-replacement aftermarket rebuild kit is precision-manufactured with industrial-grade, fluid-resistant polymers to ensure long-lasting pressure retention and reliable stopping power. We offer transparent pricing with fast, fully insured, FREE shipping directly to your repair facility.
⚠️ STRICT HYDRAULIC PART RETURN POLICY - PLEASE READ ⚠️

Once hydraulic brake fluid has been introduced to these seals and diaphragms, the kit cannot be legally resold as new. Please utilize proper diagnostic procedures to verify that your hydrovac housing is not pitted or scored beyond repair prior to ordering. All sales on opened hydraulic rebuild kits are final.
