re "But, since these are hydraulic, I don't know what you would adjust. Hmm" I just wrote a big thing the other day addressing what is adjustable on vanagon clutch hydraulics, what commonly can wear and be a problem, how the whole thing is self-adjusting at the slave cylinder .. that the only adjustment is push rod length from clutch pedal to clutch master cylinder etc. etc., ----- Original Message ----- From: "Raymond Paquette" <raymondpaquette@GMAIL.COM> To: <vanagon@GERRY.VANAGON.COM> Sent: Thursday, September 23, 2010 3:53 AM Subject: Re: "Wish in one hand, _____ in the other..."
