Is the brake pedal(design, length shape etc) the same for a power disc brake compared to a manual disc brake? Any help appreciated.

Yes same design manual vs power brakes -

Difference is in the way the pedal attaches to the master cylinder - power brakes use an additional belcrank to change the amount of force being exerted.

Yes the bellcrank reduces the pressure you can apply with your foot. It also places the master cylinder higher up on the bulkhead than the manual brake version.

If I remember right, some of the bell cranks had a little spring, and some did not. Anyone know what that's about?

Thanks for all the replies. I was a little confused because when I converted to manual brakes with the correct pushrod the brake pedal was sitting real high. I then noticed that there is a bracket with adjustment that holds the rear tail light switch which can be adjusted to lower the brake pedal. I dont think that should affect the m/c since I have not added fluid & bled the brakes yet.

The spring was used to hold the belcrank rod during assembly to aid in aligning everything

Doesn't ring a bell. Got a pic? I must have had about 15 of them pulled out at one time. Been selling them off for years. Probably have another 8 or so right now. No springs. Not very hard to assemble.

Mean while, back at the ranch. Are you sure that you have the right rod for your model of car? After bleeding the system, let the pedal return back and stop. Then adjust the switch into the pedal. Someone please correct me if I'm wrong.

This is my concern. Without bleeding the m/c the brake pedal sits too high. Its a pushrod from a 70 cuda manual brake car. The donor car was a 4 speed and I have an automatic. Think that may be the difference?

Auto/4spd don't matter,....is it possible you didn't "seat" the rod into the manual master, as a small hard rubber ring is placed on the tip of the rod, and it pops into the master cylinder's bore with pressure, locking it in place, to prevent it from falling out, this may be the reason you have a higher pedal

I thought about that but it looks like its in all the way which seems to be only about an inch. I also depressed the pedal all the way and if I did not seat it on the bench I'm sure it seated when the pedal was depressed all the way.

If you feel the brake pedal is still too high, use the adjustable manual pedal rod from Mopar Performance to cure your ills

Thanks for posting those pics Dayclona. Here's a pic of the real thing. The hook on the top end of the spring is bent spread a little so that it can't fall off once installed. The bell cranks that came with the spring have a groove that the spring is meant to sit in. I never was sure why some had a spring and some didn't. It seems like there's more that don't have it. I'd agree that it isn't very hard to assemble without the spring.

I've sometimes wondered how to identify which car a particular bell crank goes to. The one I pictured above is stamped with the letter "E" near the spring. Does that mean it's for an E body? It seemed to fit my Challenger just fine. What about other bell cranks? Do they all look pretty much alike? Maybe this info would help the original poster identify if he had the right part?

Would it be normal for a manual brake pedal to sit higher than a power brake pedal? More leverage so you can really push on it? It's been a long time since I had manual brakes.

Interesting about the spring. I wonder if they removed it after assy?? I went out in the yard and checked six 71-4B's and no springs. All are St Louis cas if that matters.
