My PA-12 brake handle does not have a spring. You pull the handle to engage the brake as it slides over the ratchet. To disengage, you press the thumb lever while pulling slightly to get it loose from the ratchet & keep pressing the thumb lever until all the ratchet teeth are cleared. The pull of the brake cable sort of acts like a spring to keep the brake hanle engaged on the ratchet and pulls on the handle to release the brake when the thumb lever is pressed.
The first photo is with the parking brake engaged.
The second photo is with the parking brake disengaged.
Let me know if you need more photos. It's a tight spot to get a good view.
If posting these photos worked, that means I successfully graduated from SJ's remedial photo posting class.
