Jabiru main landing gear question

[PureCaboose]

Bolts replaced, new brake disks installed and taxi runs done.

 

Trying to get the balance between too much space between the disks and pads and too much travel in the brake lever.

 

I just need to araldite in the screw in fittings for the fairings and it will be good for a flight test (and I can get back to flying).

Nothing pulls the Pads back. The pack of pressure should be enough for them to turn freely.  Nev

Thanks Nev, the brakes are more akin to mountain bike brakes that automotive brakes. I will set them up the way I set up my MTB brakes and see how that goes. They work, just need to be adjusted properly. 

 

Compared to before the before brakes they are fantastic.

 

New disks on the left, old disks on the left. Have a zoom in and have a look at the bearing surface on the old disks.

Lack of pressure,  also.(Not pack)  Yours are designed to handle water Any bit of wobble will move the discs away .  Nev

On a normal disc brake caliper the square section o'ring pulls the piston back because it twists a bit when the piston moves through it.

I only have experince of two aircraft disk brake installations - I have always thought that the rotating "floating" disk (as in free to move horizontally) is the main factor in moving the pads away/back😈

I wouldn't think THAT is the case. If the wheel bearings get loose, THAT will straight away give you pedal travel before  brake application. A "floating disc" reduces the effect of disc warpage (Shuddering.)  U/Ls don't need Brakes like race cars  have, but they need to be reliable. ( Like when the plane in front of you stops or you're turning close to things) The DH 82 didn't HAVE Brakes . Nev

The Caliper itself has to float freely, too. Not too clear in the Vid. A disc brake assembly can end up quite weighty. Something from a Mountain Bike should be OK. You don't require sustained High energy braking in most normal ops Clevelands are Drum. A good form of brake Could be in the wheel as a multi Plate clutch as some larger aircraft brakes are. Nev
