Amazon has Carlyle 800-6 4ply tires straight rib for $50, I have these on my plane now. They are showing wear and need replacement. I would like taller tires but haven't decided yet and $100 for the Carlyle vs $220 for the 21" tall 800-6 tires is a consideration.

I'm going to talk to the Matco guys at Sun N Fun about braking power.

I stopped by matco last week,    they have a backing plate  that that you can mount a brake caliper on both front and back.   I've got access to extra calipers so only picked up the backing  plate.   usually it comes as a kit with two plates and two calipers

with the bigger tires you will need the extra brakes On Mar 14, 2016 10:37 AM, "Rick Neilsen" <neilsenrm(at)gmail.com (neilsenrm(at)gmail.com)> wrote: 	  Quote:

John Williamson had dual calipers on his Kolbra.

 

Another caliper on my MKIII would be nice to have.  I can not quite hold my aircraft at wide open throttle.

I have 8.00-6 tires and one Matco caliper was not enough.  I added an additional newer Matco caliper on the existing wheels and now I can lock a wheel to make a sharp turn and also hold tight at run up.  See pictures.

Rex/Kolbers:



I like that.  Much beefier looking caliper.



What is the mechanical advantage of your brake pedals?

Rex, the problem with this setup is you have a rigid caliper mount, a rigid disk mount, and single action calipers. Where is the movement that allows the caliper to squeeze the disk from both sides? My guess is that this is why you weren't getting stopping and holding power.I have a customer with Matco brakes on his Highlander, but they have slide pins so the caliper can move to bring both inside and outside pucks to bear on the disk.

My trike's brakes have slide pins for the disk instead, but the outcome is the same and the caliper grips both sides of the disk.

Take a look at the disk brakes on almost all cars. They have single action calipers mounted on slide pins so the caliper can grip both sides of the disk.

Rick Girard

PS For builders out there. If you are getting ready to mount Matco brakes with single action calipers think through where the brake dust is going and mount the caliper so the slide pins are UPWIND of the pucks. If you don't the dust turns the slide pin lube into lapping compound. The builder of the Highlander didn't and my customer was going through brake pucks every 30 hours and having to replace disks every 60 hours. This on an airplane that rarely sees a paved runway. At the last caliper rebuild I showed him the problem and got him to let me reverse the caliper mounting. He's at 60 hours and the brake pucks show little wear.

The mechanical advantage is about 4.5:1 with the new design.  I modified the brakes to fit my feet as it was difficult not to ride the brakes while taxing.



The next time I'm at the airport I'll take some pictures of the new brake pedals and also check if the calipers are dual acting.  They are the Matco setup and have not been changed.  I assume they would be dual acting.

Attached are pictures of the brake pedals I modified to fit my feet. 



 I bought new Matco wheels about 2 years ago as they are thicker and Matco had cracking problems with the old ones.  I ordered the new machined caliper with the wheels as they have a larger piston than the old cast versions.  The braking was better but still not acceptable.  I then mounted the old calipers on in addition as the wheels were drilled for dual calipers and the mounting holes were the same.



Now the braking is great.

Looks good, and I bet they do work much better.
