Actually it's the other way around. When these things are
manufactured overseas, metric hex stock is common while imperial
dimension stock is near impossible to source. Result is that
replacement parts are often delivered with metric dimensions, so we are
now forced to be adding metric tools to our traveling tool kits.<br><br>

To continue research, we must go to McMaster-Carr and see if
their hex stock costs more in the larger sizes, and how much.

<dd> One kind lister recommended Speed Bleeders a couple of weeks
ago, and I bought them for my MGB, SB 3824 for front brakes, SB 1428 for
rear, and SB 71620 for the clutch. It was time to change the
hydraulic fluid, so seemed opportune to install these.<br>
<dd> Thanks for the recommendation. They made the job quick
and neat.<br>
<dd> Instructions are OK, but let me add that one should try to
pinch the brake lines with ViceGrips to minimise loss of fluid, and pinch
the clutch line even if you don’t do the others. All three
SBs were of different wrench size from original bleed screws. Have
wrenches ready for both sizes.<br>
<dd> We had two cars to do, hence had two people. What the observer
learned, watching from underneath, was that three pumps for each wheel
will bring clear, clean fluid to both front and rear brakes. <br>
<dd> $38 well spent.<br>
