pigil ang takbo(parang naka brake lagi)

[duncan_sheek]

update po:

I asked my cousin to bring it to the mechanic bec meron akong pasok.
they did a test drive, talagang apat na gulong ang naninikit at pigil ang takbo.
the mechanic's recommendation is to replace the hydrovac.
so my cousin bought a surplus hydrovac at pati na din ang brake master. so whole assembly na ang ipinalit(hydrovac and brake master)

question no. 1. faulty hydrovac ba talaga ang dahilan kaya pigil ang takbo at parang laging naka-preno?

questin no. 2. since na-install na ang new hydrovac and brake master. iba ang pikiramdam ko sa brakes. konting apak lang ay preno agad. parang sumubsob ako sa konting apak. is this normal? sa tingin ko parang hindi but I want your expert opinion. Thanks again.

for number 1: yes a FAULTY Hydraulic vacuum booster will usually have that symptoms... i have experienced that with our assembled AUV where the brakes seems to be engaged all the time making the brakes get hot... replacing the booster have solved the problem

for number 2:thats a good sign your brakes are working properly especially your brake booster...

Yan ang problema ng hydraulic booster ay yong seal sa loob ng booster na kapag na-rapture ay hindi na normal ang operation, it wont push back the pedal dahil may by-pass sa normal valve and will hold the pedal down kaya palaging nainikit ang preno mo.

Kunin mo yong booster na pinalitan nila dahil pwede mong e-rebuilt at bibili ka nang gasket kit, very reasonable price. Gawin mong reserba o di kaya ibinta mo.

thanks dreamer and yapoy.
so tama ang ginawa ng mekaniko na palitan ang hydrovac. ang bili ko ay 2,500 for a surplus one.
I have the old one and will keep it muna.
