Hello All,
I decided to stay with the TR4 stock front brake calipers for my vintage =
racer, but as I took a look at the 25 year old units from when I raced =
in the 80=E2=80=99s the calipers don=E2=80=99t look like any TR =
calipers. I must have changed them. I don=E2=80=99t know what there off. =
Can anyone identify them?

I believe the TR6 calipers bolt right on to the existing set up and are =
more available. I assume they would perform as well and use the same =
size disks? Any comments. Most Vintage rules allow similar replacements.

I have attached two pictures for you to view.

Thxs. Steve & Matthew

You are right John, that caliper was used on early TR-3's, and 3A's.=C2=A0 =
The later 3A's had a caliper that was similar, but didn't have the external=
 tube which delivered brake fluid to both halves of the caliper.=C2=A0 The =
later TR-3A calipers did not have this external tube.=C2=A0 The very early =
TR-4's also used the same caliper as the later TR-3A's, without the externa=
l tube.=C2=A0 The caliper in the picture, and the one which came after it (=
without the tube) were interchangeable.=C2=A0 They were not interchangeable=
 with the later caliper used on the TR-4, as John mentioned below.=C2=A0 Th=
e rotor and caliper mounting bracket were different.=C2=A0 I think this lat=
est style caliper was also used on the TR-3B's, or at least some of them.=

That caliper looks like the one fitted to the TR3 and early TR3A (according=
 to the Moss catalog) and uses the 11" rotor and related brake pads and har=
dware/plumbing. The factory may have used this old-style caliper on the ear=
ly TR4 if they were leftover stock or your car was converted back.=C2=A0 If=
 you want to run the later style caliper and pads (like the 16P), you have =
to change over the caliper mounting bracket and use the smaller 10 3/4" rot=
or.=C2=A0
