I just bled my Matco brake system from the bottom up with the commonly used HF oiler and some tubing. Worked very well and was easy to do. Pumped until fluid was coming out of the reservoir and then repeated on the other side.
I thought I had a problem because it seemed my brake pedals were not moving much at all. I called Matco and talked to tech support. He thought maybe my reservoir wasn't vented so I removed the inverted check valve I had installed. Same issue...very stiff brake pedals. I also double checked to make sure the calipers were not compressed...they were not. I could spin the tire. Lastly, I verified the shafts were completely extended on each master cylinder.
Following Matco's suggestion I found someone to sit in the plane and depress the brake pedals. Sure enough the calipers compressed as they should. The crazy thing is, the toe of the brake pedals don't move more than 1/4" for the brakes to fully apply...is this right??? Seems like a couple inches of travel would be nominal. Anyone else had this issue on a brand new set of master cylinders and calipers? Maybe things loosen up over time or after following the brake "brake-in" procedure?
