Thanks.  After removing and inspecting, I think the spring was binding =
on the threads and staying shut.  I am going to removing spring and =
screw and reinstall.  My front tires were locked up prior.  Amazing.  =

I've had mine disabled since around 1975.

The only downside to disabling the valve is that you may notice a low =
pedal after hard cornering.
At least for me, I've always still been able to get good brakes on the =
first application, the pedal just goes down farther than it usually =
does. Kind of disconcerting if you aren't expecting it, but it only =
takes one pump to bring it back up.

There is a modification to eliminate the low pedal, developed by "uncle =
jack" Drews IIRC and sold today by TRF (and probably others). Probably a =
good idea if you're going racing, but not really required on the street, =
IMO. I forget the change point offhand, but the factory quit fitting the =
valve at some point, either during TR4 or maybe when the 4A was =
introduced.

My front brakes feel like they are dragging and I heard that it can be
caused by faulty restrictor valve assembly (part number 116197 in Tr4 =
parts
manual).  I have same part on my 62 early Tr4.  The calipers have been
rebuilt, new seals, ss pistons, hoses and dot 5.  New master cylinder =
too.
Any harm in removing the spring and "screw" internals on the restrictor
valve so fluid flows freely.  Also heard that you don't really need
restrictor valve. =20
Thanks in advance,
