Knock on wood, I have never had that problem. It just seems that the cylinders are prone to leak a lot more than they should. I would think cylinders, both wheel and master, should last a lot longer than they do. --- On Thu, 11/17/11, Denis Dodson <coocoo@xxxxxxx> wrote: From: Denis Dodson <coocoo@xxxxxxx> Subject: [tcb] Re: repair story To: tcb@xxxxxxxxxxxxx Date: Thursday, November 17, 2011, 4:57 PM It’s the treading where the line goes to the cylinders. I could not get a good thread no matter how I tried. Had to take off the cylinder, thread in the line and put the cylinder back on the backing plate and I used plumbers tape. I don’t know that the tape is a good idea in an automotive use, but it did stop the leak.

I have changed so many wheel and master cylinders on my busses I think I could do it in my sleep. The current leak, lower cylinder on the left, is not more than 3 years old. About 3 years ago I rebuilt the entire front brakes on that thing with all new cylinders. I heard that Steve Chamberlain is an expert on the split bus brake systems. Maybe he has some ideas. --- On Thu, 11/17/11, Eric Woodall <ericthomaswoodall@xxxxxxx> wrote: From: Eric Woodall <ericthomaswoodall@xxxxxxx> Subject: [tcb] Re: repair story To: "tcb@xxxxxxxxxxxxx" <tcb@xxxxxxxxxxxxx> Date: Thursday, November 17, 2011, 8:20 AM I've got the same problem currently Sammie, which is the reason I haven't driven it in a while.

I drove the panel van to the VW club meeting the other night and the front brakes were pulling hard to the right. OK, got a chance to look at it this morning; sure enough wheel cylinder leak on the left had given the shoes a good coating of brake fluid. Order two new cylinders. Will be here in a couple of days. It's always something to keep them happy. --- On Wed, 11/16/11, Denis Dodson <coocoo@xxxxxxx> wrote: From: Denis Dodson <coocoo@xxxxxxx> Subject: [tcb] repair story To: tcb@xxxxxxxxxxxxx Date: Wednesday, November 16, 2011, 12:23 PM So, I have gone back to work, painting apartments and condos and houses for a rental management company and Murray is my work truck. He loves it and he goes to work every day, but he started a miss and a hesitation from a standing start and got worse soon. I cleaned my points with a little sandpaper and it seemed to run a little better, but still bad. I changed my spark plugs, I put in new set of points that was in my tool box. No joy. I bought and put in Petronix ignition (because I hated setting the gap on the points) and set my timing and still I had a miss. It wasn’t sporadic anymore it was a steady power loss. OK. Not the coil, no cracked dizzy cap, rotor OK, new ignition, new plugs, what the hell, I’ll change the spark plug wires. In doing so I couldn’t get one old one to come out. I had disconnected it at the dizzy and at the plug, but it wouldn’t pull free. I had changed my alternator months ago and, apparently, when I put the top shroud back on, I pinched the wire between the shroud tin and the head tin. What an idiot. I lopped off the old one and put in the new wire and… Murray runs like a rocket. Isn’t it a great satisfaction when you solve a problem and your bus runs well after?
