Title: Rear Wheel Cylinder Bore Diameter
Post by: OldGuy on February 27, 2018, 01:32:19 PM
Guys, what is the correct bore diameter for the rear wheel cylinders on a GT-350H (built in the mid-November/December time frame)?

Thanks in advance for your help.

Originals were 29/32".

They should be the same as the stock V8 Mustang.  They were not unique to the GT350's.

+1, and I think they had little teeny bleeders

Yes the small bleeders are a feature of all early/classic period wheel cylinders

Thanks to all for your quick replies! Does anyone know of a source for new cylinders (with little tiny bleeders) or, if not, restorable cores?

Thanks so much for the help.

Hi Frank,

See the link below from Brant at Virginia Mustang, about 1/4 the way down you we see three orignal restored and sleeved wheels cylinders.  The cast part number is 38767.  Those are the ones.

Good luck

Cory

And if you want to get really detailed they should each have 2 white paint spots.

Can someone post a photo of the bleeders?  Gold or silver color?

Thanks,

Hi Steve,  The bleeder here is the small version.  I did buy some NOS gold bleaders that should be around here somewhere. ::)

These have been rebuilt and sleeved.  They will need the two white paint marks that Dave mentions.

Hi Cory!

Thanks again!  How are you and Mark doing?  You guys saved me again.  Gotta get those cylinders changed out but I HATE brake fluid!!!  Love those pictures!

Cheers,

Steve

I reproduced the 13/16 bore and the 7/8 right and left bore   small bleeder if this helps.
