The Stovebolt Site Forums The Parking Lot Big Bolts Brakes on a 2 ton

My truck (1952 6400 2 ton) has the hydrovac unit.
Does anyone know if a power assist brake unit can be used to replace the hydrovac?

Thanks,

yes

What is the power assistbrake unit

Traditionally they are vacuum boosters bolted to a master cylinder, like most newer cars and pickups have.

Alternatively you can use a hydrobooster as found on most if not all current diesel pickups. If you will have power steering this is my preferred choice by far. A hydrobooster uses PS pump pressure to help instead of vacuum, it is attached to the MC in a similar fashion as a vacuum booster.

An older solution is the hydrovac like you have, and some slightly newer versions of the same thing could be substituted.

I have a 52 6400 and I put a on the firewall split system. The vac booster/master set up was $200 at NAPA and went to a chevy 1-1/2 ton, 1997 I think. Part No# 54-71046.Used the pedal from a S-10 and built the support for it. My rear wheel cylinders were good so I just put on new front ones. I had just cleaned the seat with WD-40 and went to try them. I was slammed into the steering wheel with great force. This is now a split system so if one brake line goes bad you still have brakes. Bob
