As getting reliable Hydrovac parts is dicey and Hydrovac brakes in my case have proven too weak, I want to replace with a hydroboost system.


Repairing a 1972 C600 with the Hydrovac unit behind the rear axle. Had the hydro replaced 20 yrs ago, it was only good for 3 years and last time I drove it I had to use the park brake to stop it. Not gonna do that again.

Sizing the master is my only real question.

Anyone have experience with this?
