pflaming Posted January 7, 2009 Report Posted January 7, 2009 Been searching threads couldn't find answer to the following . In the resevior are two holes. One cleaned out easily. I have used everything from a hair pin to an extremely small dremmel bit and cannot drill through. I honed the inside til the cylider walls shine like glass yet only see one hole into the cylinder. Does the small hole go through. Seems it should. Quote
norrism1 Posted January 7, 2009 Report Posted January 7, 2009 Original master C had 1 hole. Goes out when you push the brake and returns when you let off the brake. Quote

Is the radio still humming the same tune? Quote
pflaming Posted January 8, 2009 Author Report Posted January 8, 2009 Master cylinder: I had it bead blasted, confirmed only one hole, and cylinder is pitted. Looked good after honeing, but it must have smoothed the good areas and 'filled' the bad. Will go with a new one. Radio: It still only has one tune, will research help on that and will eventually have it fixed or restored. Looks great!!! Paul Quote
Don Coatney Posted January 8, 2009 Report Posted January 8, 2009 On a P-15 master cylinder there are two holes and they both must be open. I would think the trucks are the same. Quote
pflaming Posted January 8, 2009 Author Report Posted January 8, 2009 (edited) Bead blasted the reseviour and there is only one hole in this Master Cylinder. Bead blasting also revealed pitting in the cylinder which honing did NOT reveal, so this MC will now be bronzed and made into a lamp beside my kids baby shoes. The P-15 MC is shaped quite differently than the truck MC. They are not the same. Edit 12 / 17 / 09 Took this MC to my local parts store. Parts man took one look, took it back to the shop and opened the second hole. IT IS SMALL, size of fly's terd. Even when opened it was hard to see. So glad I took Don's statement, 'two holes' serious. Edited December 17, 2009 by pflaming Quote
Young Ed Posted January 8, 2009 Report Posted January 8, 2009 Its not dead yet. You could have it sleeved and put back into service that way. Quote

pflaming Posted January 8, 2009 Author Report Posted January 8, 2009 Don and Ed: Don, I agree, yet I took a VERY small dremmel bit and all I hit was cast iron, could not get a hole going and after blead blasting could not see a second hole on the inside. Ed: Who sleaves and at what cost? A new MC runs around $170. PF Quote
Young Ed Posted January 8, 2009 Report Posted January 8, 2009 The shop here last I heard was about 110 after sleeving and buying the rebuild kit. Its brake and equipment warehouse in minneapolis. They have a website www.brakeplace.com but it was down the last time it was mentioned on the site. Quote
Don Coatney Posted January 8, 2009 Report Posted January 8, 2009 Who sleaves and at what cost? PF Go to the links section of the main web page supporting this forum. Scroll down to the brakes section. Then scroll down looking for brake cylinder re-linning. Quote
pflaming Posted January 8, 2009 Author Report Posted January 8, 2009 http://http//www.whitepost.com/brake.html Tried Whitepost via their web site. Not active, at least not from my computer. Don, you, Ed and I all must be in for lunch or a break. I am finalizing my wiring front to rear today. Sure would be nice to have a rack! Gets tiring crawling under that truck and I have it up on 9" blocks! Quote
Don Coatney Posted January 8, 2009 Report Posted January 8, 2009 Don, you, Ed and I all must be in for lunch or a break. My job at this location (Dulles, Virginia) is complete. My motel room is paid for tonight so I am just hanging out this afternoon. I will get up bright and early in the morning and spend about 12 hours driving home. I am still about 60 postings behind in my forum reading. Quote
pflaming Posted January 8, 2009 Author Report Posted January 8, 2009 I remember those trips, traveled all day to solve a problem in one hour, then had the day left over. Did see 48 of the 50 states though, but a lot of that alone. Lots of interesting sights on the back roads of Virginia and other places. Sometimes even a little spooky did some U-turns when I didn't feel comfortable. Remember a little store that was stocked with 1940 basics, like oil lamps, gasoline powered washing machines, all new, not a antique store. Blew my mind! Have a good trip, appreciate your input to the forum. Paul Quote
Jim Yergin Posted January 8, 2009 Report Posted January 8, 2009 Paul. For sleeving the m/c you might want to check out this company. http://www.applehydraulics.com/ I used them and was pleased with the price, the work and the quick turn around. Jim Yergin Quote

Gets tiring crawling under that truck and I have it up on 9" blocks! Call Whitepost (540) 837-1140) if you want to get in touch with them. They've done all the cylinders in 2 of my vehicles. Good work, probably the best, but there are cheaper places. It'll come back read to bolt in. A year ago master cylinders were $160 + about $15 to ship it back. However - I had the master cylinder from my 3 ton 47 dodge done, a 1 3/4" big one, it was a total rust mess. Cost $350 when done, but was like new. It looked just like yours, just bigger. Gene G.

stevenelle Posted January 12, 2009 Report Posted January 12, 2009 Regarding the number of holes in Pilothouse master cylinder - both the B2B and B2C I have had, have 2 holes between MC reservoir and the cylinder. The rear hole (toward the back of the truck is so very tiny that you will have difficulty seeing it. It is the relief port that allows pressurized fluid to return to the reservoir when brake pedal is released. Mine has gotten plugged preventing excess pressure in brake system to be relieved. I have taken the smallest wire I could find - a stiff 28 ga wire and finally got it down in the hole and tried to clean it out. It took a lot of effort, but finally, black fluid came back up into the reservoir after the hole was cleared. I doubt they make a dremel bit small enough to go through that hole. Quote
