Guest Posted August 27, 2003 Share Posted August 27, 2003 I think I need to change the brake shoes on my 48 Chrysler Windsor, but I'mstopped by the anchor bolt adjustment procedure called for in the ShopManual. The procedure calls for the use of special measuring tools in orderto adjust the eccentric anchor bolts so that the curvature of the brake shoeis parallel to the curvature of the brake drum.Am I likely to be able to find these measuring tools somewhere? Or is there away to make the anchor bolt adjustment without using the Chrysler-specifiedtools?Thanks,Doug Link to comment Share on other sites More sharing options...
Jon Robinson Posted August 28, 2003 Share Posted August 28, 2003 Doug: Having the tools is best, of course, but you can improvise. First, a note: When you get your shoes relined, specify that you want them done in 3/16"-thick lining, not the usual 1/4" stuff. If a rebuilder near you balks, call Valley Brake in Fontana, California, and they'll fix you up. Once you have to shoes on, adjust them to where you can slip the drum on over them. Make a measuring device out of a piece of stiff wire or a big measuring caliper, and you want to adjust the eccentric anchor bolt and the in-and-out adjusters to where the shoes form a near perfect circle like the drum. As you work the adjustments, try to drum on, and set it to where the shoes don't drag. Yes, there are different specs for the "heel" and "toe" of the shoe, but it's only thousandths of an inch, and you can get it close enough by trying for a good circle that fits within the diameter of the drum.

Guest Posted August 28, 2003 Share Posted August 28, 2003 Thanks for the good advice, Jon. I'll give it a try.Doug Link to comment Share on other sites More sharing options...
plymoth Posted August 29, 2003 Share Posted August 29, 2003 Major Brake adjustment:Drill a 1/4"hole in the face of the drum from the inside of drum next to shoe contact area.Install drum & rotate drum around shoes using the drilled hole as a peep hole to set the ankors to make perfectcontact between shoes & drum Link to comment Share on other sites More sharing options...
Guest Posted August 30, 2003 Share Posted August 30, 2003 Interesting idea, Plymoth. A hole would certainly make it easy to set the adjustments, but I'm afraid I'd be skittish about drilling holes in the brake drums.Thanks,Doug Link to comment Share on other sites More sharing options...
plymoth Posted September 1, 2003 Share Posted September 1, 2003 I've used this method for 45yrs! If you don't like the hole, Drill the hole with a letter "R" drill & shalow tap the hole 1/8"-pipe thread & install aallen head pipe plug.The "ChryslerMaster Drum Gauge" doesen't work as it adjust the brake shoes to the gauge- not to your specific drum.It helps to slot the ankor bolts with a hack saw in order to hold the ankor bolt with a screw driver while tighting the hex nut.Then recheck shoe adjustment again to be sure nothing changed while tighting the hex nut....Plymoth Link to comment Share on other sites More sharing options...

plymoth Posted September 1, 2003 Share Posted September 1, 2003 Let me explain the drilled hole.The hole is drilled from the inside of the drum toward the face of the drum (face of drum being the part of the drum that is drilled & tapped to receive the lug bolts).The hole isn't drilled on the 2"wide surface that the brake shoes makecontact with when the brakes are applied.I hope this makes my suggestionmore clear.......Plymoth@ webtv.net Link to comment Share on other sites More sharing options...
Guest Albert Posted September 3, 2003 Share Posted September 3, 2003 Plymoth the Packard's have a slot cut like you say so a feeler guage will slide between the drum surface and the shoe, makes it real quick adjusting. Link to comment Share on other sites More sharing options...
