Power brakes

[60overdrive]

Does anyone know where to get a 12 volt electric vacum pump my 1960 Impala 348 tri power now rebult with a mild cam, does not seem to have enough vacum for the new disc brakes.:

Those things are made by Gast and another company probably in the Graingier catalogue...But.... Why not a reservior tank?

with a " mild " cam , you should have plenty of vacuum to oprate the brakes. You might first want to investigate any other issues, vacuum leaks etc....

If my memory is correct I believe the 60 chevy tri power cars
came equipped with a vaccum tank for the same reason you are
having a problem.
I think they where mounted on the inner fender under the
hood hinge.

60overdrive, I think bluescream is on the right track. I put power disc brakes on my 61' 348, it had factory power brakes, and didn't re connect the vacuum tank and it works fine. Are you using all new parts and, are you sure you have the push rod adjusted properly both from the master to the booster and the booster to the peddle? If it is not adjusted correctly and is pushing on the vacuum diaphragm it will result in a hard peddle. Good luck Dan
