At the SCCA Driver's school I took at Nelson Ledges in NE Ohio, we were instructed; "Throttle good, brakes bad!". Nelson is/was a 2.1 mile 13 turn track. Brake at 4, 6, 12, & 13. And yeah, after 20 hard laps, there was some brake fade, but nothing to worry about.<br><br></div>Paul<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Sep 8, 2015 at 3:35 PM, Richard Shepard via Datsun-roadsters <span dir="ltr"><<a href="mailto:datsun-roadsters@autox.team.net" target="_blank">datsun-roadsters@autox.team.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:16px"><div><span></span></div><div>When I took my Roadster to a SCCA track nite at Portland the stock bakes sucked big time.

response / braking torque to pressure is Linear with disc brakes and

valve on the rear to limit braking torque.<br>A proportioning valve is
miss named as it changes the pressure response to pedal travel - which
flattens the torque response of the drum brake.</div><div dir="ltr"><br></div><div dir="ltr">Phil</div></div></div></div><br>________________________________________<br><br><a href="mailto:datsun-roadsters@autox.team.net" rel="nofollow" target="_blank">datsun-roadsters@autox.team.net</a><br><br>Donate: <a href="http://www.team.net/donate.html" rel="nofollow" target="_blank">http://www.team.net/donate.html</a><br>Archive: <a href="http://www.team.net/archive" rel="nofollow" target="_blank">http://www.team.net/archive</a><br>Forums: <a href="http://www.team.net/forums" rel="nofollow" target="_blank">http://www.team.net/forums</a><br>Unsubscribe: <a href="http://autox.team.net/mailman/options/datsun-roadsters/aultgc@att.net" rel="nofollow" target="_blank">http://autox.team.net/mailman/options/datsun-roadsters/aultgc@att.net</a><br><br><br><br><br></div> </div> </div> </div></div><br>________________________________________<br>
