1934 Ford Brake/Clutch pads

[WRA]

Folks I've done search but didn't quite find what I was looking for.

I'm looking for just the rubber pads, not the rubber that's bonded to a new metal frame.

I bought Macs bonded set and they have a 1/2 x 20 stud that is incorrect for the car. I would like to use the Henry Metal and get a replacement rubber pad.

Can anyone suggest a vendor that sells just the rubber?

Some of the 33 pedals use the 32 pads B-2454 with nuts and lock washers to attach them to the pedals. Later pedals are threaded for the 40-2454 pads that thread into the pedals. I do not believe anyone is making just the rubber to fit over a worn pad, at this time. There are older rubber replacements but fit and durability of old rubber???

Ford never offered separate pads to replace the worn portion of the pad and base assembly. The only pad replacements were aftermarket and the face of them was totally different from the Ford design. I mention that as you state that 1/2 x 20 threaded assemblies are "incorrect". Late '33 and all '34 pedals used 1/2 x 20 studded pedal pad assemblies. While the pattern on the face of the replacements from Mac's may be incorrect or not, the studs and their threads are correct. Perhaps you have early '33 pedals as stated above or your '34 pedals have been modified.

Maybe his 34 has tapered threads like my 34 has. Drake has/had both threads.

This leaves me puzzled. I know that David is the expert authority, and I also know that the pedals in my late 33 / early 34 are not 1/2-20. Maybe my pedal assy has been changed ??

Bob,

I'm away from my car stuff so I shouldn't have piped in without checking my NOS pedal pad assemblies. On second thought, I believe that the threads are pipe threads, i.e. tapered as stated above. Notwithstanding, lock washers were still used even though they likely weren't required.

I actually have 3 sets of pedals, including the ones in the car. The Henry pads spin right on all 3, but the Macs bind after a turn or so. I havnt forced it but it feels cross threaded, possibly maybe even the wrong pitch. I'll get my thread gauge out letter today and compare the two.

As a side note, I was told that 40 Ford rubber pads would fit the Henry Metal. I just don't have one to try.

My understanding is the 1933-48 is 1/4" pipe taper, that allowed the pedal to be lock into the arm with just the stud.

First double check your arm with a piece of 1/4" tapped pipe. Then try extending the thread (and depth of taper) on the pad with a 1/4" pipe die.

Just pulled a pad and checked it. 1/2-20 nut will start on it and seems like a good fix for about two turns and then it tightens up. Checked the threads against a 1/4-18 pipe tape and looks like a perfect fit. However, on my pads the threaded stud is straight, not tapered.

[WRA]

Seems the repop pads have a 1/2 x 20 tapered thread and the Ford are 1/2 x 20 straight thread.

Here is a summary sheet that I made up a few years back when I was confused (common occurrence) about which pedal pad to use for a rumble seat step pad. Notice the difference in the threads between the B-2454 pad and the 40-2454 pad.

My repop pads have the straight thread, the thread is 1/4-18 pipe thread just not tapered.

How does that work? The holes in the pedals are clearly 1/2

[JSeery]

Not in mine, I have two sets of original pedal assys and they are 1/4-18, they may look like 1/2 inch.

From post #9 above "Just pulled a pad and checked it. 1/2-20 nut will start on it and seems like a good fix for about two turns and then it tightens up. Checked the threads against a 1/4-18 pipe tape and looks like a perfect fit."

They may look like a 1/2-20 and it may start for a thread or two, but that is not the correct size on the ones I have. Both the pedal assembly and the repo pads I have are 1/4-18 NPT and fit perfectly.

Have you tried a 1/4-18 NPT to see it works in your pedals? Get a short section of pipe from a hardware store and try it.
