Just got myself an Ammco 8000 brake arcing machine. It is still in the trunk of my car after 2 weeks as I came home with the bloody flu. Been laid up for 2 weeks now. Worst part is a pulled chest muscle from coughing.Pain is amazing. First time taking flu shot and BAM. Here's your sign. Will report more later.
 
Hope you're feeling better- flu was bad here in the midwest as well.

Once up and running, will you be offering your services to others? If not, anybody know who would do this on an Atlas with 2LS front brake in the Chicagoland area? I asked Ed at Morrie's a while back and he said he didn't do brake work...
 
Yes, I was going to offer this to our forum users. I have to get it organized and do my own first to see what a diff it makes. I am sure my brakes have never seated in even after 15 k miles. From what Dog says it made a heck of a difference. I was going to arc mine as he did but figured what the hay. Get the frigging machine. Stand by for updates.
 
I got my rear shoes re-bonded by a brake specialist in Whangarei, but gave him the full set up so he could true the linings up to suit the drum.

Hi
What the heck dose this machine look like :?: ?
I do mine on one of my lathes?
Got quoted a massive price for a brake shop to do some, may be they have one of these machine?

Best Regards

The difference is like dragging your feet or real brakes, I only did the front, I have no trouble locking up the rear. But they also have to be adjusted correctly. When I started on mine, I was getting maybe 10% of the shoe hitting the drum. Ended up with over 90% in contact.
 
brake arcing machine.
This is what I do.
Lathe with over 6-1/2" swing.
mandrel with a double taper. Fixed taper at the chuck end and screw on taper at outer end.
simple device to prevent backing plate rotation on taper while cutting.
pieces of shim stock to set your running clearance between each shoe and each cam.
process=cut to measured drum diameter + if required increase shims until % of cut area to your satisfaction.
 
Hi
Pretty handy tool by the looks of it, I do my the same as Dyno Dave, certainly worth the effort if you want good brakes.

Those machines have been around for a long time. presume you know to check the pivot is not worn and flogging around etc. Will be a good investment when set up properly.
