rear brake adjusting tool

richmccolman · Post by **richmccolman** » Sat Aug 18, 2012 10:51 am

Does anyone know where I can get a 7mm square-opening rear brake shoe adjusting wrench for my '72 coupe? A regular 7mm open-end wrench won't budge the adjusting bolt without tearing up both wrench and bolt head, even after applying penetrating fluid to the rusted bolt threads. (The last time I adjusted them, I think I used a small vice grip, but doing that repeatedly is sure to eventually bugger up the square head on the bolt.)
I wonder if one of the specialty mechanics tool distributors (Snap-on, Matco, etc) carry such an item (assuming that such a bolt wasn't exclusive to the Honda 600s).
Thanks,
Richard

Will a 1/4" drive extension used backwards? It measured almost 7mm across.

I tried a 1/4" drive socket - a bit too small. Thanks for the response though.
Anybody else got an idea?

Perhaps an adjustable tap driver might do it... Lisle also makes a set of 8 tap drive sockets but I can't find the exact dimensions on them. I can measure the sizes tomorrow if you like, they're at my work...

The adjustable tap driver is an interesting idea, Derek. (I do wonder whether I can get one that will work in the confined space between the rear brake backing plate flange and the lower connection point for the shock, though. Kinda tight in that area.) I actually have one style of adjustable tap driver myself. I'll have to see if I can make it work. If you think you have something at work that might do the trick, I'd be interested in finding out what it is.
Thanks,
Richard

Guys, in the time you have been talking about this subject, you could have taken the backing plates off, repainted them cleaned up the slave cylinders and been done with it all.

Wow, I wish!

The Lisle tap drive sockets don't fit much better than a 1/4" drive, the nearest one is about 6.5mm. And the square part is set back from the front of the socket, so you'd have to grind it as well. You would probably have to modify (destroy) a tee handle tap driver by grinding the fixed handle off to fit... Perhaps it's time to take Johns advice and free the thing up.

Even if you get a tool to fit the square you wont be able to turn it because it's seized and the last time they were adjusted they were very tight (not quite seized) and were "rounded" off so the next time, ie now they are really seized and wont turn because they are rounded off!! they are so easy to strip down and free off do it, you know it makes sense.
