Hi Mike,
Please let your Triumph racing experiences flow and be shared.
Dave H.
p.s. Where is your TR3 now?

I had planned on staying out of this but my fingers have over ruled my
brain....
My poor old TR3 has NEVER faded a brake at any race anywhere! That includes an
amazing bumper to bumper race with an ex IMSA, 6cyl Vitesse at Road America at
a previous TR reunion. I led him twice and we finished with a separation of a
few inches. There was no other 4 cyl Triumph within sight. Similarly at tracks
as brutal on brakes as Sebring at the 12 hr support race. Ran it many times. NO
FADE, even at the old hairpin config.
You are working on this problem too hard. Or.....as once advised by an old,
successful pro racer "more throttle, less brake"
The real issue to worry about is rear axles, front spindles and front and rear
hubs. Modern tires are the villain here, not brakes. Actually, modern tires
make the brake issue smaller.

Brakes are definitely a limiting factor in many vintage cars. One of the things
that keep them vintage. The rules for the three clubs below essentially say -
calipers of the same size and number of pistons, rotors ditto.
SVRA says - 3. Alternate rotors and drums of the same diameter and thickness
are permitted. Rotors may be drilled or grooved.
4. Alternate calipers or wheel cylinders must be of the same material, design
and number of pistons as the original component. There must be no increase in
the frictional surface of the pads or shoes
VRG - Brakes must be the original type (disc, drum), size, and design as
supplied by the manufacturer, or listed option, for the model. Updating from
drum to disc will result in reclassification if eligibility timeline (e.g.
1960) is crossed. Lining and pad materials are free. Rotors may be drilled or
grooved, but must be same diameter, thickness, and material as originally
supplied. Modern aftermarket calipers are not permitted.
VDCA - Braking systems must be of the same type as standard for the year of
manufacture or as homologated by the original manufacturer for that year.
Updating or backdating is not allowed.
1. Aftermarket brake calipers are prohibited

Hello All,
I am starting the selection for front brakes on my TR4 racer. Naturally the old
stock ones are out. Are the Toyota four piston calipers good enough? They are
less expensive and easy to get, with disks and assorted pads. Which after
market models work well and bolt wright in? Which disks work the best and last?
10 inch, 10.5 inch -- bigger or smaller?
All comments are welcome!
Thank You,
Steve & Matthew
Florida TR4 Racing
