This actually started last year and I'm just now trying to sort it out.<br>> <br>> Basically, after pumping the brake pedal a few times the front brakes lock up (only the fronts). If I crack open either bleed screw they free up. In fact, cracking open the line anywhere going back to the master cylinder frees up the brakes.<br>> <br>> I have bypassed the booster, replaced all of the rubber lines and rebuilt the calipers. This seems to leave the master cylinder. I disconnected the brake line from the master cylinder and put a short line on it that feeds back into the master cylinder reservoir so I could bleed any air out of it. That all seems to work okay.<br>> <br>> So, I'm looking for other ideas. <br>> <br>> Thanks,<br>> Joe Brown <br>> _______________________________________________<br>> <br>> <a href="mailto:tigers@autox.team.net" target="_blank">tigers@autox.team.net</a><br>> <br>> Donate: <a href="http://www.team.net/donate.html" target="_blank">http://www.team.net/donate.html</a><br>> Archive: <a href="http://www.team.net/pipermail/tigers" target="_blank">http://www.team.net/pipermail/tigers</a> <a href="http://autox.team.net/archive" target="_blank">http://autox.team.net/archive</a><br>> <br>> Unsubscribe: <a href="http://autox.team.net/mailman/options/tigers/fast427@sbcglobal.net" target="_blank">http://autox.team.net/mailman/options/tigers/fast427@sbcglobal.net</a><br>> <br>> <o:p></o:p></p></blockquote></div></blockquote></div></div></body></html>
