Each brake rod connects to each wheel with a pin/cotter pin combination. The pins wear and are no longer round. This end of the rod has a turnbuckle like adjuster with a stop nut, and wear in the turnbuckle doesn't introduce slop that can't be adjusted out.

Unfortunately the end of the brake rod that goes to the cross shaft, they have an eyelet that becomes egged out and they are more challenging to make round again.

Many brake rods have become un-straight.

There is another pin in connection between the pedal and the cross shaft.

Third Gen Automotive is my go-to for parts in this instance.
