Hydrovac Brake Booster – 2512076X (International/IHC)
The 2512076X is a frame-mounted remote booster (no bracket included) engineered for IHC hydraulic brake systems. Typical specs for this family include a 12-3/4 inch diaphragm and approximately 17-5/8 inch overall length, with common porting of 1/2 inch input, 1/2 inch-20 output, a 3/4 inch air cleaner tube, and a 1/2 inch NPT vacuum supply. It’s a proven replacement when the original Hydrovac shows low assist, vacuum leaks, or internal bypass, and it preserves OE pedal feel on loaded or downhill stops.
Applications (verify by unit ID & plumbing):
- International Harvester Loadstar 1600 — documented in mid-1970s service (e.g., 1974 and 1978) using Hydrovac ID that crosses to Bendix 2512076 or 2512076X.
- International S-Series — early-1980s examples (e.g., 1980) shown equipped with a Hydrovac matching 2512076.
- General IHC Coverage — International/IHC trucks specifying Bendix fourth-series single-diaphragm Hydrovac with OE reference 277082C92. Always confirm your tag number and line sizes.
Cross-references (for identification only): 277082C92 (IHC), 2514917, 51-8002 (A1/Cardone), RV2512076X (Haldex). Match by the ID tag on your existing booster and the port style before ordering.
Fitment notes: International used several Hydrovac variants that look similar. Check the stamped ID (2512076 / 2512076X), overall length, and port thread styles against your unit. This model is the single-diaphragm, frame-mount configuration and is supplied without a mounting bracket.
