I have past e-mail showing the torque on the 5/16" bolts is 45 ft/lbs and
for the 3/8" bolts it is 75 ft/lbs.
I used these figures when I rebuilt my calipers and have had no issues at
all with them.
I had to split mine because one of the bolts what broken when I bought the
car.

Subject: [TR] FW: Early TR4 - Front Brakes
I now have one of the front brake calipers apart. I know that you're not
supposed to split them, but that is the only way that the pistons were going
to
come out after decades of nil use. Also, I am not going to trust the
condition
of the 44 year old seal between the 2 halves; Moss shows that they have them
in
stock. The 2 pistons have badly rusted where they were exposed, but all the
"hidden" areas look to be in good condition.
So to today's questions:
1 - Has anyone split a caliper and succesfully put it back together without
leaks? If so, what torque values should I use?
2 - Both Moss and TRF show replacement pistons. TRF state that they make
their
own from Stainless, don't know about Moss. Anyone have any experience with
either of these, or others?
As always, thanks for the assistance.
