Brake Progress

Another concurrent project has been the Beringer brakes. As an upgrade to the standard Matco brakes, there are some extras that need to be considered. As previously mentioned the Beringer system came with a proportioning valve and a parking brake. Both of which required some head scratching to figure out mounting options.

Finally got it figured out and got all the lines made up and temporarily installed as well as the custom brackets. I had been waiting on some extra different fittings to make it all work, they finally came in and worked as expected. So, I will be final installing everything this week, then filling, bleeding and testing.

This was the initial way I had run the brake lines until I realized I needed to criss cross them so they wouldn't bind when flexing as the gear strokes. This way, I couldn't have enough slack in the line to accommodate that flexing. Plus, the fittings are much more exposed.

Here is a shot of the caliper quick disconnect. It will allow me to take the wheel/tire off or change brake pads, all without having to crack the brake system. The quarter turn quick disconnect is a lossless connector that won't leak or allow air into the system, pretty slick.

Another shot of the quick disconnect...

Here is a shot of the final position of the proportioning valve/bracket and parking brake/bracket with the new lines temporarily attached. That gray tube above them is the flap handle in the down most position.


This is the 45 degree bulkhead fitting exiting the fuselage bottom by the landing gear attachment. The line running upward is from the parking brake.

Here you are looking down onto the proportioning valve and  parking brake. This is the area between the seats. The flap handle was raised out of the way for the pic. Nothing is final installed at this time, just mocked up for fitment.

Here is a shot from behind the front gear mount looking forward. It shows the two brake bulkhead fittings through the fabric set in the criss cross position. There are two 45 degree brake line fittings that screw on to these bulkhead fittings.
 

More photos of the completed system soon...
