Standard to power brake-help please
I am converting to power brakes on my 69. I have a new vacuum booster. What else other than different hard hydraulic lines do I need? Do I use the same brake pedal rod that goes from the brake pedal to the back of the master cylinder, or in this case the booster?
Thanks for your help.

The brake pedal has two holes. The top hole is for manual brakes and the lower bottom hole, the one furthust from the pivot is for power brakes.

Pictures
Pictures would be great. I have all the holes drilled out and have no problems mounting the unit on the firewall. My question has to do with the linkage connection from the pedal to the back of the booster. The linkage that came with my new booster has a threaded nut end and the rod on my pedal is also a threaded rod, but different. This is where I am confused.
Thanks for all of your help.

Re: Pictures (69Myway)
I am thinking of doing this conversion on my 1970 and would be interested to know how you have got on, and if you find a big improvment in your cars braking. One thing you say you have a new vacume booster have you also got a new power brake master cylinder as I was told they are different ?

Re: Pictures (69Myway)
I have manual brakes and see no need to change. But, many people in here periodically post questions about converting. Maybe you can do a technical article and have it posted in the technical area for those that want to do it in the future.
Good luck with your project.

Pictures and description would be greatly apreciated!
If I let others drive, I'm always somewhat embarassed
about the pedal-force needed. I always tell 'em:
It's a 33 year old car. You need to hit the brakes
HARD!!!
And the first time they try and stop the car I invariably
hear the "Wow, I didn't think it was going to be THAT
hard!"
So yes, I'd like to go Powerbrakes, too!

Re: Standard to power brake-help please (69Myway)
There must be something wrong with you current brakes. The manual brakes work just as good as the power and the pedal effort should be very small. I pefer my manual brakes and wouldn't want power brakes on a Corvette. My manual brakes will stop on a dime and I don't even notice any pedal effort. I just don't understand the motivation behind the conversion. You may be trying to fix a problem that you have with the manual brakes

OK, I'll take some digital pictures at lunch and E-mail 'em. I have driven both types and I prefer the boosted ones. Besides, I feel better about my wife driving it. Now she only complains about the steering, which I am NOT changing! :D

Re: Standard to power brake-help please (Wrencher)
I got one decent picture of the linkage under the dash. Man, it is difficult to take 'em blind and upside down! :mad Basically it is a threaded rod out of the booster with a "u" shaped clevis and a pin through the pedal. What we need is someone that has one all torn apart, or access to a dismantler. :yesnod:
E-mail me at hcabplanalp@ucdavis.edu for a copy of the picture.

Re: Pictures (British Mark)
I have had them both ways, and prefer power. Besides, my wife too will be driving this car, and at 4'11" she needs all the help she can get. Not to mention, the power brakes are just part of the whole equation. The car is getting power everything. Any of you that have seen my project develop also know that it is running electric headlight actuators and an electric wiper door. In fact, my a/c system uses all electric operation. Sooooooo, the brakes will actually be the only "vacuum" (or shall I say...part that sucks) on the whole car.
I bought the car as scrap, so I have to replace everything anyway. So, yes Mark, I will be slapping on a new master cylinder.
I will get that picture guys, thanks.

Re: Standard to power brake-help please (69Myway)
I drove my car for 12 years without power brakes and made the switch to power this summer. What a difference. I too was ashamed to let others drive my car for the braking effort was way too high and everything was new in my car. Now the braking effort is effortless and the brakes feel so much more powerful.
