Stupid Question #1, SAE or Metric

[Recoil Rob]

So I have my 2002 4dr. 4WD up on jack stands, all pads and rotors off and it occurs to me I'm not sure if the all the nuts and bolt are SAE or metric. While disassembling it sometimes a metric socket fit better, sometimes a SAE.

While I'm at, it tomorrow it gets put back together and new brake fluid put in the system with a pressure bleeder. What's the proper order for bleeding the wheel cylinders?


thanks,

Rob

Probably metric, but use whatever fits best.

Bleed the brakes with the farthest (rear passenger) point first and work your way to the closest point.

Yep, that's the way I was old school taught ( on my1966 Triumph Spitfire) but recently, get back into mechanics, I see that my Honda CRV w/ABS had me do it the exact opposite, starting at the nearest and ending at the furthest.

From what I've experienced, the body, suspension and brakes are metric and the engine and frame are SAE.

There is no rhyme nor reason what size nut or bolt Ford uses. Just did my brakes and rotors and the caliper mounting bracket bolts on one side were 15mm and the other side was 17mm ( I own it from new so nobody switched on me). Just find the socket that fits and use it.

The only SAE tool I've needed on the ST is a 5/8" spark plug socket where the actual size 16 mm.

very simple really if 1/2 is too big and 3/8 is too small then its metric

What about 7/16 ? :

Yes, a lot of the ABS systems now get finicky. The wife had a Pontiac that was special, too.

I know after buying a new aftermarket "caliper bolt/slide pin kit" for my Ex last year, the caliper bolt heads in the new kit were a different size than the factory ones. Not sure if this is why you see a difference in sizes, but just a suggestion to consider in case yours were ever changed before.
