Brake pedal arm question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Bowtiefreak · 03-20-2005, 08:09 PM

I know there are two styles.
1.) with one hole and non-power brakes
2.) with two holes and with power brakes
I want to add the second hole to my brake pedal arm so I can add power brakes to my truck. The power brake booster rod connects to the bottom hole.
The question is: I believe its about 1 inch appart but is it 1 inch from the center of the top hole?

Help me if you can.
Thanks Ron

Never drilled one adding factory power brakes, the neat linkage behind the booster takes care of that. Hole drilling is for boosters that have a straight pushrod, like 73-up or aftermarket. Brian

I didn't have to drill any holes to put power brakes on my 70. It only has one hole, you just have to adjust the rod to the length you need.

Me too, I've done several power brakes swaps. The stock pedals hook right up to the new booster linkage without any extra holes needed. The stock one hole works fine.

OK thanks. Why do some have two holes?

Big trucks used it maybe?? They have some weird tandem booster setups. Brian

I think you may be looking at the bracket upsie-down here is a pic from my truck(68 C-10) where I installed a 72 power brake setup.
