    Diesel starex van 1997 model - malakas o humihina ba ang air pressure galing sa vacumm ng alternator punta sa hydrovac kapag inapakan o hindi inaapakan ang accelerator?

    Halimbawa, para malaman kung malakas ang air pressure ay tinatakpan ng daliri ang hose na nakakabit sa hydrovac galing sa alternator vacumm.

    Maraming salamat po sa mga gusto magcomment dito sa tanong ko.

    are you asking about the amount of vacuum assist whether you pressed the brake pedal with your pinggur or stepping on it? the vacuum assist provided by the pump should be more than enough even at idle speed even with repeated application of the brakes.

    sir oca,

    a bit of misinformation here...vacuum is the absence of air (theoretically). the pump connected at the rear of the alternators of diesels is what we call vacuum pump. some are driven via the camshaft or other engine mechanicals. it evacuates air from the hydrovac/booster unit at the rear of the brake master cylinder. it does not supply "air pressure". instead, hihigop ng hangin ang vacuum pump. thus the name vacuum pump. if the booster is evacuated of air there is a difference in pressure between the ambient and the inside of the booster unit thus the braking force assist.
