Matco brakes

[HighWing]

I already posted my experience with the Matcos, but Paul's response reminded me of a couple of things. I replaced the original linings on both of the brake sets on the two Model IVs. The first one, I did drill the rotors for weight reduction, but on the second I reduced the rotor dimensions to only the portion that was actually in contact with the pads - also for weight reduction. The second time, I replaced the pads with Cleveland linings - Part # 66-106 (Aircraft Spruce) A caution, the rivets sold for the installation are too short by about a sixteenth inch or so.

Same response as before ...........

I'll keep working on the bleeding problem.
Thanks for the help,

I had a similar problem on my RANS with the MATCO brakes. It took a lot of bleeding to get the air out. I ended up using an oil squit can filled with brake fliud. I put a bunch of rags around the master cylinder resevoir to catch the overflow, when I was bleeding them. I attached a small, snug fitting tube from the squirt can nozzle to the bleed screw on the wheel cylinder and kept pumping in fluid until there was no longer any air visibly coming out of the master cylinder. I actually had to do it a couple of times, with testing the pedal hardness, before I finally attained proper working brakes. I have now moved up to 29" AkbushWheel Airstreaks on the plane and the single pucks are not suffiecient. I am going to have to move up to dual calipers or double puck brakes.
