I should point out that I designed and built the toe brakes that Joey is running on his plane. and if you want to lay into them they will wrap a 600 psi pressure guage.After his first landing gear and brake conversion, his comment to me was these things are super strong and I'm going to have to watch it and he has said somewhere on this site that he could literally stand his plane on its nose.This performance was achieved with 21 inch tires w-62 internal calipers and 1/8 inch brake line.I've only ever ran accross 2 people who could properly determine the leverage on an avid flyer toe braking system. One was George Happ and the other one was an individual who talked to George back in around 2002.Here is the link to Joey's original conversion from go cart to matco brakes.

Drilled disc rotors,are in fact drilled for rain
so the brake linings do not hydroplane over the rotors which would cause total loss of braking
Floating rotor's, are specifically made to dissipate heat

get rid of the 1/8 " line
exchange it for 1/4" line
it works much much better for pressure and that alone will increase the pressure
most Matco brake issues are do to the master cylinder not getting correct 2.5 to 1 ratio when depressing toe brakes
or actuating the brake assemble of the master/toe brake combo
Tow brakes have a complicated geometry,
and if not done right can seriously hamper the efficiency of the brakeing
If you were to take the line off the caliper
and hook a pressure gauge up in that spot you could gauge the amount of pressure when applying the brake
from there you could adjust the master cylinder toe brake set up to give more pressure
There is probably very few out there who can produce above 450 psi pressure
which is the minimum that is needed for the brakes to work optimum
At least as far as the Matco installation pamphlet I got from Matco states
450 psi is just enough pressure and is at the bottom of the scale of what is acceptable pressure
no lower than 450 psi and up to 600 psi
over 600 psi and you actually get caliper/brake pad problems such as,
caliper deflections that will reduce the torque increase
Also,making sure both brake lining pads move in and out correctly and freely/smoothly
if the one pad that rides(compared to the pad that the piston moves as it is a one piston caliper)
if the ride pad gets sticky,then right there your braking is decreased by 50%
the calipers(and pads/linings) need to be able to float,if there sticky and gunge up they loose efficiency
these few problems when addressed, can make a dramatic difference in your braking

Hey Dude,
I have a new set of bungees for my Avid B model that I got from
Brett at Airdale. I'm going to use the Airdale bush gear instead so I don't
need them. They are 90" I believe, with the formed loops. He charged $100
for them - you can have them for $50 plus a few bucks shipping if you're
interested.

As a young machinist, serving a 4-year Toolmaker apprenticeship, I had a boss who would never admit to ever making a mistake.
This man was a schoolteacher before becoming a foreman.
The old Journeymen Toolmakers told us that he was probably right: "A man who never does anything cannot make a mistake!"
"The good machinist learns from mistakes - his own and others'!"
I'm learning from Leni, and now you!!!! HA!

If you are in Celceas, THATS HOT! Guess about 40?

I have an early Magnum builders manual. Tell me which control parts you are asking about, and I will see what is in the book, and copy if it will help you. I am a dinosauer at puters - so send me a private email with your address and I will copy the pages you need and mail them to you at no charge. If you dont know how to send message thru this site, I can tell you how.

On the kit list question, EAA didn't know but said it should still qualify.
FAA said no problem, but sometimes you get different government answers-ever call the IRS for answers?
Does anyone have drawing of the controls? Thank you.

Joey,
Probably my last comment, since you have gotten so much advice.
If you have a pressure problem with your nylon lines - Look in Spruce, and you will see same size nylon lines listed in two different pressure ratings. Unless someone knows why not, then opt for the high pressure lines.

Have you checked your braking pressure?

C5Engineer added a post in a topic Looking for some landing gear part numbers
Mike thanks for the info. Everything is the same. I used to run my lines down the back legs of my old gear so the line was long enough to run down the front legs of the new gear. I'm using the 1/8" line from the bottom of my MC's to the calipers. I had a hard time getting the air out of the system this time around. I also think I may have gotten some fluid on the pads. One of my pads is missing a chunk too that's why want to replace them.

Joey:
Don't drill your rotors.It is of no benifit.Sleeving the master cylinders is a waste of time as you have line psi coming out the wazoo already.Matco sets their torque and energy ratings at a line psi of 450.When you lay into your brakes hard you are approaching the 600 psi range already.when you went to the taller gear if you had to do some hyd line splicing and used rubber line there will be a problem with pressure obsorption. You also mentioned something about an issue with getting the brakes to bolt up to the new landing gear, having to do some adapting. If there is excessive flexing in this area then your brakes not work like they used to.Brake pads are easily buggered as well.very fine line between use and abuse (speaking from experience)
My speculation for your ponder.

The sleeve and piston kit should give you a lot better brakes.
IMO, Drilling rotors only lightens them - dont see why it would increase braking power - might even wear pads faster - but should run cooler for long braking runs, which you probably dont need anyway - wont increase brakes for static runups.

Yes the timken numbers are on the race. I just didn't want to tear it apart, put it back together, order parts and then tear it back apart again. I share a hangar and can't keep my plane on a jack. I am running MC-4D master cylinders. Guess I will just call and see what they can do. I've seen people that drilled their rotors too. I am thinking about doing that mod also.

John_L_Seagull added a post in a topic Size of trailer to move a Kitfox?
couple things I failed to mention
I use something to brace the rudder from moving back and forth
as it will rub on the folded flaperons when swinging back and forth in the wind
I use two pieces of lathe,covered in soft cloth that I made
one on each side of rudder,then zip strapped together on each end and in the middle
to prevent the rudder from moving
I also have a small wooden dowl I made,with two holes drilled in it on each end
I use it in the cockpit to brace the ends of the flaperons when folded
The wooden dowel fits right into the slots where the flaperon control rods connect
I use some quick locking pins to secure it
This helps in making the flaperons ,so they do not wiggle back and forth/rock back and forth(side to side)
At the back of the plane,I use a very small light weight bungee chord to tie together the ends of the flaperons
This also helps them from twisting around back and forth and rubbing against the rudder
It also helps,with tightening up the wings when folded
otherwise they rattle a bit from being loose
These are just a couple of other things I do, when trailering my plane

I finally moved into something that will haul the family around. The Sedan is very comfortable, especially when compared to the 140. Speed is not it's forte but I'm not in much of a rush. From the factory the Sedan only had one door on the passenger side, but when this Sedan was upgraded to 180 HP, seaplane doors on both sides were installed.
The more I fly it the more I like it. It's a little like driving an old truck, with a real solid feel to it.

VVERY STUPID ME:
a few sleeps ago i went to check an area for deer sign- stopped the engine and looked about for 15 mins then jumped back in and took off for the next palce .
Ashort while later and maybe 500 ft above the trees the engine started to cut out and stop and after the initial panic I saw id switched the fuel off on the last stop- i usually leave it on.
after what seemed like an eternity of cranking the electric start she roared into life but i was close to landing in the trees
id say that avid header tank had 5 mins in it which in this case was enough.
Id fallen into the old, getting distracted , complacency trap of not ddoing even a quick prestart check

Ed.
The increase would be 56%.
Joey,
What Master cylinders are you using? If they are 5/8" bore the intensifier kit would increase your braking pressure quite a bit. My masters are the MC-1 with the 1/2" bore and I have very good braking. I do use the RA66-106 pads they may have a greater friction coefficient.

jOEY,
About all of the Timken bearings I have seen have the number stamped on one of the races. Have you tried looking at yours?
