Suzuki - Lehman Brake Prob ?
This intermittent brake problem has been hounding me for the last 8 months. Sometimes after stopping and shutting off the trike, upon restart, the rear brakes are locked up. They've never locked up while riding, only after a shutdown. &amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
I'd crawl underneath and crack a bleeder valve and the brakes would unlock and I'd be on my way again. Didn't happen on every ride and when it did act up, it might have been once per ride. By cracking the bleeder valve and having that unlock the brakes, this told me that it's a hydraulic problem and not mechanical. Got to a point where I wrapped some pipe thread tape on the bleeder valves and that held up for about 5 months with zero problems, then it happened again. &amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Decided that air must be getting in from either the bleeder valve threads or thru the wheel cylinders, so tore everything down and am in the process of renewing the brake system. Installed new wheel cylinders, new brake shoes and new brake spring hardware. Ordered a rebuild kit for the rear brake master cylinder and still waiting for that to arrive.&lt;br /&gt;<br /><br />
&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Even tho' this trike is powered by a 2002 Suzuki VS800, the brake fluid reservoir and the rear brake master cylinder are from a Suzuki VS1400.<br /><br />
<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Noticed that the brake line from the banjo fitting on the rear brake master cylinder runs to a brass T-fitting, 3/8&amp;amp;quot;.<br />
<br />
That section of line has the banjo fitting on the master cylinder end and what looks to be a valve of some sort on the other end and that valve screws into the T-fitting.
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Question: Is this valve a &amp;amp;quot;residual pressure valve&amp;amp;quot; ? If so, does anyone know if this valve could have been causing the issues I've been having with the brakes locking up ? &amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Also, does anyone know what the replacement brand and part # for this valve might be ? &amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Noticed that the brake line itself for this section says &amp;amp;quot;Goodridge&amp;amp;quot; so am guessing that Lehman fabbed up this section of brake line. &amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
&amp;lt;br /&amp;gt;&lt;br /&gt;<br /><br />
Thanx in advance for any and all help with this &amp;lt;img src=&amp;quot;images/smilies/thumbup.gif&amp;quot; border=&amp;quot;0&amp;quot; alt=&amp;quot;&amp;quot; title=&amp;quot;&lt;img src=&quot;images/smilies/thumbup.gif&quot; border=&quot;0&quot; alt=&quot;&quot; title=&quot;<img src="images/smilies/thumbup.gif" border="0" alt="" title="<img src="images/smilies/thumbup.gif" border="0" alt="" title="" class="inlineimg" />" class="inlineimg" />&quot; class=&quot;inlineimg&quot; /&gt;&amp;quot; class=&amp;quot;inlineimg&amp;quot; /&amp;gt;
