<p>You still have air in the system. Keep bleeding. The reason the bakes pump up in 2 to 3 strokes is that at that point you have compressed the air enough to transmit force to the fluid.</p>

<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Changed
<span style=""> </span>out the front callipers (to 4 pot) and the problems started.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">After repeated bleeding on first push,<span style="">
</span>pedal went to the floor.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">After 2/3 pumps the pedal came right up and held.<span style="">
</span>After about 30 secs of no pressure on pedal <span style=""> </span>goes to the floor again.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Pistons are all in contact with pads and pads with disc; all looks good at callipers.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Suspecting a faulty MC changed it out.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Primed the new MC with fluid prior to installing.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Same story after another 1.5 pints of DOT 4 fluid focusing mainly on bleeding front callipers and booster (new);
<span style=""> </span>also bled rear drums.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Pedal still goes to the floor on first pump and comes up after pumping as before.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">No visible leaks and inlet from reservoir shows no leaks: tapped callipers with mallet to dislodge any air pockets.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">I am using the one man bleed system a with clear tube into a container and close the bleeder valve
<span style=""> </span>with no visible air at nipple and full tube of fluid to container. BTW also changed clutch MC at same time and no problems with bleeding etc.</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Have now run about 1.5 pints of fluid through the new MC -
<span style=""> </span>perhaps am being <span style=""> </span>too impatient ? </font>
<span style=""><font style="font-size:11pt"> </font></span></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">But no evidence of any air after about 0.5 pint. Typically how much fluid is required to clear air from MC and lines ?</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Now sort or suspecting the inlet to MC from reservoir but for life of me cannot see how air can get in with no visible fluid leaks,</font></font></p>
<p class="MsoNormal" style="margin:0cm 0cm 6pt; line-height:13pt"><font face="Calibri"><font style="font-size:11pt">Any ideas from the more AH experienced listers appreciated.</font></font></p>
