As others have commented, the TR wasn't the first car ever to have front disc 
brakes, though it was 
certainly the first British sports car in the more budget price sector to have 
them. In that regard, 
it was a bit of one-upmanship against the likes of Austin Healey, MG and 
Sunbeam Talbot.

I'm surmising here - and I'm sure Paul Richardson would confirm from the 
extensive records he has 
from his late father, Ken - that TR3 heavy braking with drum brakes on the 
European Alpine rallies 
of the early 1950's led to serious brake fade and possible boiling of fluid? 
Although it wasn't a 
TR, my own bug-eye Sprite had terrifyingly inadequate front drum brakes 
(through fade) when used on 
those same roads. Needless to say, the Sprite wasn't being driven nearly as 
fast as a TR but the 
lack of effective braking was a good alternative to an effective laxative!

Don't construe this response to indicate that drum brakes per se are 
ineffective. Rolls Royce and 
Bentley used excellent four shoe front drum brakes for years and I think up to 
the end of the 
1960's. An uncle had a RR Phantom which I drove on occasions. I recall that 
stopping about three 
tons of the best English drawing-room from around 80mph in a somewhat urgent 
situation was both 
impressive and very effective.
