<div dir="auto">Actually - part of the problem is the BN1 and some BN2 bleeder valves originally had a separate ball inside the slave’s bleeder which the little ball sealed the system. Over the years i’m sure that ball has been lost and maybe you think the bleed screw is sealing the slave when it really isn’t until it’s fully cinched. That also can contribute to the inability to get a firm pedal. </div><div dir="auto"><br></div><div dir="auto">Cheers,</div><div dir="auto"><br></div><div dir="auto">Alan</div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 31 Aug 2022 at 4:16 PM, Simon Lachlan via Healeys <<a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div lang="EN-GB" link="#0563C1" vlink="#954F72"><div class="m_-9048889340569780999WordSection1"><p class="MsoNormal"><span style="font-size:11pt;font-family:Calibri,sans-serif">Yes, for sure, an Eezibleeder helps.

The car has been professionally restored & appears to be in excellent condition. Today, we tried again to bleed the system following the shop manual. I.E. backing off the adjusters on the front & back & bleeding & then readjusting the brakes. The results were the same. There seems to be an excessively large amount of pedal travel before the brakes are engaged & when engaged they feel "spongy". We have access to 2 other 100's for reference. Any help would be greatly appreciated. Also, we are not clear on the adjustment of the free play of the master cylinder. <u style="font-family:"Comic Sans MS""></u><u style="font-family:"Comic Sans MS""></u></span></p><div><p class="MsoNormal"><span lang="EN-US" style="font-family:"Comic Sans MS";color:black">Gary Hodson <u style="font-family:"Comic Sans MS""></u><u style="font-family:"Comic Sans MS""></u></span></p></div></div></div></div></div>_______________________________________________<br>
