Parking Brake...

[comfortcat]

OK!

Time for installing a parking brake.

Is Matco still the best choice? I'd like the dual valve. BTW: I'm going with the Bonoco brake lines if that makes a difference.


I see they have a straight value and a 90 degree valve.

Option? I have not bought the valve yet so I have options.

I think I got this one from Van's. I mounted it above where the normal lines would be on the firewall. This keeps it away from the rudder/brake pedals.



Used a scrap of the hat section for the tipup canopy release as a mounting bracket. This way I could stick some nutplates behind it and not have the bolts poke through the firewall. The plate on the side acts as a position limiter for the control arm and holds the control cable.



I used Bonaco lines. The ones coming up from the brake cylinders are shorter than normal, since they don't have to loop over the rudder pedal tubes.



Last step was to add a microswitch for a parking brake warning light.



Parking brake control is mounted below the panel on the side.

Agreed! I've always liked the idea of a parking brake on my 9A, but have had concerns about adding "parking brake released" to my pre-landing checklist. The microswitch idea is a winner!

There is a "Check Brakes" on all checklists. Wouldn't the brakes feel funny with parking brake valve closed?

Also, taxi at full throttle might be a hint too.

I can't take all of the credit on the microswitch.

I stole some of the ideas in my parking brake implementation from others on this forum.

Startup checklist, yes. But I don't have "Check Brakes" on my PRE-LANDING checklist, as there's nothing for me to do if I check them and they go to the floor. I still have to land and I certainly can't service them from up there.

Beautiful Bruce. I would like to highlight that in your installation the arm down position is brakes off. I did mine the same way after a friend who mounted his the opposite way landed with his brakes on after vibration and gravity applied his parking brake for him, in flight

All Best

Can you tell me where you purchased your parking brake control cable? Do you have a part number for it? I like yours better than mine.

The cable is from ACS

A1840 T-Handle Button Lock Dash Control

Works great and has a very solid feel.
