The right brake pedal was a stiff push as expected but the left brake went easily to full compression. These brake master cylinders are at least 5 years old and they&#8217;ve been activated numerous times without hydraulic fluid since they&#8217;ve been in the plane, my bad. I took apart the master cylinder and the internal o-rings on the shaft are deteriorated.  The above image doesn&#8217;t show the internal o-ring which is the most deteriorated.  I ordered two new <a href=\"http:\/\/mcmcrbds4%20-%20mc-4%20seal%20rebuild%20kit\/\">MCMCRBDS4 &#8211; MC-4 SEAL REBUILD KIT<\/a> from Matco.  Buna-n o-rings are used in this assembly. Mil-H-5606 aircraft hydraulic fluid or compatible fluids like Royco 782 are recommended.  Better to find out about this stuff now than while taxiing for the first time.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I&#8217;m not entirely sure why this morning I felt the need to grab each brake pedal and test the brakes again, but glad I did.
