Delco 18014080 Hypower Booster Repair Service

Professional diagnostic and board-level repair service for this Delco 18014080 Hypower Booster.

Delco 18014080 is a Hy‑Power hydraulic vacuum brake booster used on medium‑duty GM trucks (TopKick/Kodiak) and similar heavy‑truck chassis. Common failures include loss of vacuum due to cracked or worn piston seals, internal leakage in the booster chamber, or failure of the vacuum pump/pressure regulator that supplies the assist system; symptoms are sluggish or no brake pedal feel and a “vacuum lost” warning light. For diagnosis, first verify the master cylinder’s vacuum pressure with a gauge while the engine is running, inspect the booster for any visible cracks or oil leaks, and check the vacuum line connections and filter for blockages or damage.
