I'm interested in knowing who some of the larger manufacturers of calipers and micrometers are. I know that Mitutoyo, Starrett, Brown & Sharpe, and Mahr are all big, but who are some others?

force with table?
force frame with pin?
steel tape?
string?
plumb bob?
inclined plane with friction block?
stopwatch?
double pulley?
uniform bar?
weight pan?
set of weights?
meter stick & wooden block?
protractor?
micrometer with steel bar?
venier caliper with aliminum cylinder?
bench pulley?

just give the use of any of them, answer as many as you caa please? one who answred the most will be given 10pts.

one of the two caliper bolts (the larger ones) broke in half when i was changing brake pads, am i out of luck? do i need a new caliper or can it be drilled out? the other of the two is also seized up in there and wont budge no matter what i do.

On rough pavement there is a rattling. Is it normal for a brake caliper base to expand to the point that the pads float enough to rattle or is it a rattle in the strut?
When brake is on no rattle.The shop said caliper base is not original and proceeded to adjust pad by putting a piece of stainless pipe clamp on base to tighten up pads. Still there is noise over bumps, no rattle when brakes applied Could it be the struts? They sound OK but it is difficult to load them by pushing down on vehicle., Thanks
