  • my dad's isuzu truck with diesel engine has the vacuum pump coupled to the alternator...newer alternators without the vacuum pumps are cheaper...can we just drill a hole on the intake manifold ang tap the brakes vacuum line there...so we can use a cheaper alternator?

  • @EvendimataE Seems like that would work, but you need that check valve and NO leaks. if there are leaks the brakes wont work right nor will the engine run right.

  • M35 GOV?

  • @Sirrom0206 - no this is the vacuum over hydraulic brakes on the 1939-42 GMC 'CCKW' 6x6, it is what the Army had before the Reo-Kaiser M35. i believe all the M35 series trucks had air over hydraulic brakes (compresses air)

  • Interesting film. Now I know how my brake system funks. I must fix an broken vacum hose, then it works.
