bleeder nipple box wrench size????

[t2jeff]

Running to Sears at lunch to buy a wrench for bleeding my brakes. Anyone know the right size to fit on the nipples???? What about the MC???

Thanks!!

I'm sure someone will post the sizes, but between the bleeders and both MC ports you'll need 3 different sizes. I'd suggest just getting their 5 pc flare wrench set and then you'll have what you need.

What he said, one can never have too many tools. However the bleeder size should be 3/8" I just rebleed my system and that was the size for me.

One GM caliper is 3/8, the other is 10mm
The rear drums are 5/16
That is off of memory and subject to human error

metric sizes??? My 75 has drums all the way around. I buy 3/8 or 5/16, but metric????

Anyone else?

Metric is possible…
The rebuilt calipers and wheel cylinders are often rebuilt in strange parts of the world. If the bleeder fits and doesn’t leak, good enough. Some batches might be metric head from a newer car.

Also, 5/16 and 8mm are so close they are interchangeable. I learned that when doing GM side post battery terminals. To this day I don’t know what the correct size wrench for those are?

I just bled mine last night. 10mm on the back drums, 3/8" on the front disks. But my bronco is equipped with auto parts store brake equipment and not OEM
