Here's how it works... As soon as a List member makes a Contribution through the Matronics Fund Raiser web site, they will instantly cease to receive these Fund Raiser messages for the rest of the month! Its just that simple. I really do appreciate each and every one of your individual Contributions to support the Lists. It is your support that enables me to upgrade the hardware and software that are required to run a List Site such as this one. It also goes to pay for the commercial-grade Internet connection and to pay the huge electric bill to keep the computer gear running and the air conditioner powered on. I run all of the Matronics Email List and Forums sites here locally which allows me to control and monitor every aspect of the system for the utmost in reliably and performance. Your personal Contribution matters because, when combined with other Listers such as yourself, it pays the bills to keep this site up and running. I accept exactly ZERO advertising dollars for the Matronics Lists sites. I can't stand the pop-up ads and all other commercials that are so prevalent on the Internet these days and I particularly don't want to have it on my Email List sites. If you appreciate the ad-free, grass-roots, down-home feel of the Matronics Email Lists, please make a Contribution to keep it that way!! http://www.matronics.com/contribution Thank you!

This is a straightforward task. One caliper needed honing due to minor corrosion. The other was done last year. I attach a cellphone photo of the components and another photo showing the seals and their respective positions.

I have also just finished stripping down the hydraulic brake calipers and discs on my Allegro 2000. After 4 years on a grass strip the brass plungers on the calipers were froze. Took everything apart, cleaned everything, re-polished the brass plunger ever so lightly, as well as the inside of the caliper itself. Put in new "O" rings and rubber plunger as well as new brake pads. I have not re-filled the hydraulic system yet. I did notice in your photos that you also disassembled the little master cylinder. Why did you do that? Was there a problem with it? I do have a question that I need some help on. What is the best way to re-fill the brake system on an Allegro 2000 with hydraulic brake fluid? I see no way to fill the system from the top down (i.e. through the master cylinder in the plane) with out disassembling the master cylinder itself, and then re-assembling it. This seems to be difficult and cumbersome. How do you re-fill your brake system (top down, or bottom up) and then bleed the system after re-filling?

I have had a problem with pressure whe n the system gets cold.. I have replaced the gasket on the plunger in the m aster several times.. I may have a small burr inside.. For some reason it h as been holding pressure for the last 6 months, we will see what happens wh en it gets cold again..
