parking brake issue

[jeepjseries]

1976 jeep Wagoneer parking brake issue. I can push down parking brake and it holds well, but as soon as I let off the pedal it releases. my question is what isn't working to hold the pedal in place?

You need a replacement foot pedal assembly for the parking brake in the cab, the gears get worn down or the rivet gets sloppy that holds the unit together.

Might have a broken spring in there that hold the ratchet cog down in the teeth to engage the foot pedal.

You can probably push the pedal down, then push (do not pull) the release handle, and it might engage.

If it does, then probably a broken spring.

NOTE- Do not trust that park brake to hold working like it does. Always make sure you have the rig in gear or chock the wheels.

ok thank you sir, I'll try that. Thank you for the replies. I will work on getting a different assembly.

I always have hated those types of park brakes.
Can't trust them at all!
Through the years my Jeeps park brake decided to engage and my truck rolled a couple meters and had to run to press the brake pedal to save it.

I'm replacing it with a pull park brake assembly from a 40/41 Ford truck.

The one that mounts parallel under the dash?

I remember those, and they were cool

You mean the rod type with a T-handle that pulls towards you!?

Those are cool ,but I choose for this type,

It is going to sit at the same place under the dash as the original foot park brake.

Oh yes, I thought the T handles were cool too

This old Chevy under dash type was my thought

I was thinking about the Chevy under dash type but could not figure out how they mount on the steering column and if it could work with the jeep column
Also did not find any good pictures of it and then I came across the ford type lever so that is the way I went.

The OEM pedal frame can also bend. Comes from stomping on the pedal at an angle. These pedals went through several revisions, and '76 is early.

If the frame of the assembly is bent, the pawl no longer lines up with the ratchet and the brake won't stay set. You can remove the assembly and try to straighten it, or reset/replace the pivot rivet if that's the problem. If the teeth are worn, I'd say it's done.

We replaced a lot of these on warranty in the '70s.

Wrangler YJs use a similar pedal - you might be able to make one of those work.
