I'm going to paint the engine compartment on my 73 Challenger soon (318, non-rallye car...will be a driver). It currently has manual disk brakes, but I'm thinking of upgrading to power with either a used booster or a new one from Advance. I have all the other needed parts. I'm thinking this is the time to decide...BEFORE the paint is on!
The only reason I would consider leaving the system manual is that the brakes will work the same whether the car is running or not. (i.e.:engine vacuum is not an issue)
I've had (minor) issues in the past with engine stalling and having to use BOTH feet to stop the car! No problem with the manual disk setup.
Thanks for your input!
