Up for sale is a heavy-duty brake booster / hydrovac assembly that fits Isuzu D500 HINO 204-05701 203-07040. The dimensions of this brake booster is indicated in the pictures. There is a longer version this brake booster for the same engine so it is important for the buyer to measure the old part before buying. It comes with two (2) fittings and one washer. This is a brand new brake booster, not a remanufactured part like what others are selling. Also, this brake booster is made from heavy-weight steel alloys, weighing 10 kg as assembled, while the cheaper version that others are selling are made from light-weight alloys, which are apparently cheap but they don't compare to our brake booster in terms of quality.
