Hi folks,

 I have just installed the main gear and hooked up  bled the brakes. Piston in the left master cylinder has about 1/2" of free  travel before brake pressure is applied. Right side is very tight, it has less  then 1/8" free travel before pressure is applied. Because there is virtually no  free travel I cant push the rudder pedal all the way forward before the brake  applies and the pressurized cylinder stops forward travel of the pedal.  It is not rod adjustment . I disconnected the cylinder from the pedal  and it is still tight. Also, disassembled the master cylinder-looks ok  inside.

 Any ideas?

 Eric

Eric:



If the symmetry between the pedal and the master

cylinder is correct, you will be able to apply full

rudder either direction without automatically applying

pressure to the cylinder.  This also imples that, even

if a master cylinder piston is stucked, you should

still be able to have full travel with both pedals.



Seems to me like there is something wrong with the

installation of both master cylinders.  You will need

to change the position where the master cylinder

pivots in the pedals assembly attachment brackets. 

You may need to redo those brackets.



If you check site www.matcomfg.com, there is a drawing

showing the right symmetry between the pedal and the

master cylinder.

Check your right brake, or swap master cylinders and

replenish the fluid.  See if it is the master or slave

cylinder.



To me, it sounds like the master.  See if it actually

locks the right brake with such little travel, or is

it self limiting?



I agree with what you already heard.  The cylinder

shouldn't limit the pedal travel in any case.

Eric,



Just an idea, and I don't know it it is applicable to your situation or not.



Here is what I ran into on the master cylinders. I purchased a dual brake 

system from Sky&#$^. After Sky&#$^ dissappeared, I found that I had two 

different cylinder models; two Matco MC-4A cylinders, which were the correct 

length, and two Matco MC-4 master cylinders which were too long for the 

application. The bodys of both the MC-4A and MC-4 were identical, the 

difference was in the lenght of the piston rod and some internal parts. The 

MC-4 piston rods were about 1/2" longer and resulted in exactly the same 

geometry problem with the rudder pedals which you described.



I realize that you said the cylinder length was not a problem, but there is 

some adjustment on the screw end of the piston rod which might make it 

possible to get the adjustment (eye to eye) close for the two models of 

cylinders yet still cause problems with the geometry.



I can't say you have the same problem, but you might want to check to be sure 

both sets of cylinders are the correct model number for the kit.



At any rate, Matco helped me out by exchanging the cylinders for a very 

reasonable rate and providing the tech data to figure the problem out. The 

individual I dealt with was:

George R. Happ

MATCO mfg

801-486-7574    801-486-7581 (F)

www.matcomfg.com



If the installation is still a problem, I would sincerely suggest contacting 

George. They know their products and also know how to treat people right. 

(No-they did not pay me to say that-its experience with them speaking) If you 

are stuck - I believe that MATCO will be able to help you figure the problem 

out.



Sincerely,



Dave S
