Help with 70 Camaro Brake Pedal
My car is now a manual equipped car, I'm not converting to auto, I'm adding power brakes and just need the brake pedal from a manual trrans car that was original with power brakes. Most 2nd gen brake pedals I have seen have 2 brake rod attaching points, 1 pin and 1 hole. My pedal I have now has the pin for the master cyl push rod in the top hole (manual brakes) I'm looking for a manual trans brake pedal with the pin in the bottom hole (power brakes).
Let me know if you can help....

Can you move the pin from the top hole to the lower hole? Here are pictures of my pedals if that helps. I'm not sure what year they are from because I picked them up off of e-bay.

Hey Alex,
I left a response in your thread at NastyZ28. But here it is again:
That pin is just pressed in. You can push it out & install it in the lower (power) hole. On a power brake car there is a little sheetmetal bracket that bolts to the upper hole to activate the brake light switch.
No need to hunt down a different pedal.

Amargari's pics show the stock power configuration. Hope this helps...

Thanks guys, Amargari for the pictures of your power brake pedal setup and Shane 73Z for both posts.
What brought about this conundrum is that I'm installing C5 Z06 brakes F&R on my 70 along with a Hydro boost from Paul at Hydratech. I am on my second boost unit from Paul and the M/C push rod on both units (1-long, 1-short) are too short to reach the pedal attaching points. Paul at Hydratech has been great to work with to try and figure out this problem.
The pics provided by Amargari showing his power pedal has the #8063 stamped into the pedal, I have 2 sets of pedals (both manual brake) 1 in the car and 1 on the shelf, both have the #5697 stamped into the pedal, which corresponds to the last 4 digits of the part# for the pedal in my GM 1970 parts book #3965697. My parts book only shows 2 brake pedals avaliable; W/ A.T. #3972201 and exc. A.T. #3965697 so where the #8063 comes from on the pedal in the pic who knows??
How about this, would some of you guys check your cars (manual trans / power brake) and let me know if the clutch and brake pedals are at the same height, and if not the difference in height. If the brake pedal is lower that would explain the sheetmetal tab used on the power brake pedal for the brake light switch. Now on my manual trans manual brake car both clutch and brake pedals are the same height and the pedal arm accuates the brake light switch.
This would help clear up allot of confusion and I'll just move the pin to the lower hole and use the pedal assy. that I have.
Thanks, Alex

If you are using a different system and booster system you may need to put the hole in a totally different spot. You might try what you have first.
The 79-81 Trans Ams with the factory 4 WD used a dual diaphragm booster. The disc/drum cars used a single booster. The 4WD used a pedal with a different location that the regular power brakes as it provided more assist. When I made the swap and at first kept the old pedal stopped great , just no "pedal feel". The Hot Rod article incorrectly said the 4WD needed more leverage. I looked at the pedals at first and saw the old one had more. It needed less, so I got the 4WD pedal.

Thanks, Alex
