i have drum brakes all around and i want to know what do i have to do to make power drum brakes? the service truck that i drive has power drum brakes and actually stops good for the weight of it. is all that i have to change is the master cylinder? someone tell me how it can be done.... thanks in advance. charlie

You probably need to look up one of the vendors, but in short, you will have to get the booster/master cylinder for the application and bleed the master cylinder before installation and for good measure, the rest of the system. You will need booster specific vacuum hose to complete the installation.

Check out "Praise Dyno brakes" if you serious about making 60's Chevelle drum brakes work real good power or not ......I would suggest you phone them after checking there website .... very helpful people...I have there Stage 111 drum brakes on my 66 with factory power booster ....... no disc's for me smile.gif

How do the Praise drum brakes compare to disc brakes? My car has 4-wheel manual drums, and is in dire need of some brake upgrading

My 72 rag came from the factory with plain drum brakes. Now here is the interesting part !
The original purchaser must have wanted power brakes (possibly a woman), so the dealer added a power booster. I found this out when I ordered new brake lines and the routing was different.
I've rebuilt the entire drum system and the car stops great.

hey you guys, if all that i need to do is get a power booster master cylinder and install it, then what type of doner car and what year car do i have to choose from? so that i can visit the junk yard and find a rebuildable one.....

Never really thought about it but my latest 69 malibu has power drums, thought it was odd as my last several drum cars were manual. Anyhow what I am getting to is this should be a easy mod with stock parts. OPG catalog lists boosters and master cylinders for drums.
