Question

I've removed the booster/master cyl. from my Camaro and have replaced them with a manual master cyl (disc brake) unit.
What do I use for a pushrod from the brake pedal to the m/c? Is there a manual brake pushrod available for an '80? The original pushrod was attached to the booster.

My '67 all drum uses a rounded ended, 5/16" or 3/8" fine threaded rod and lock-nut that screws into a clevis on the pedal It's adjustable and is installed w/ about oh, say 1/8" to a 1/4" play.

I'm changing everything so will have to shorten my rod or I prob. will make a spare to use and keep my stock one. pdq67

Master power has them. You need a clevis and pushrod. The rod is 3/8" I think.
You MUST use a master cyl with deep hole in the piston to keep the pushrod from falling out!
Someone told me their second gen came with manual brakes and had some kind of a guide that prevented pushrod fall out. But I haven't seen one.

David,
I called MasterPower a few weeks ago and told them what I was doing. They sent me some crappy adapter plate (that doesn't even bolt up to the studs on my firewall) and a clevis/rod assembly that also doesn't fit my brake pedal. My pedal has a pin that the brake pushrod eyelet clips over. Not much help from them...

I don't know why you would need any adaptor plate.
Maybe a resto catalog for the pushrod?

Thanks, David.
I was hoping to find one off another car...maybe someone converting from manual to power brakes.

Bill, did you ever find what you needed? What MC are you using and does it have the deep hole?

And you said your pedal has a pin sticking out? Is that the stock pedal? I hace not seen that style except in later cars, but I might have the pushrod you need.

Let me know,
Bill C.

The adapter plate is used to cover the hole and center the master cylinder. I converted to manual brakes and didn't do anything other than remount the master cylinder on the firewall where the booster once sat. My peddle had two holes to connect the pushrod to so I just switched holes. The peddle just sits higher than usual but that's about it. It was a no-brainer to switch.

Thanks guys for the info...
I didn't use the adapter plate, just mounted the MC to the firewall studs. My brake pedal has no holes...only one stud to attach the pushrod to.
I tried my local dealer...no luck.

I didn't notice before that you are working on an 80'.
You will have to figure out where the new brake pedal clevis hole needs to be and drill it.
On a first gen the upper hole is 2" below the pivot point, the PB hole is 3.25" below the pivot.
