Obviously yours have been turned. Once thinned, they can fall victim to uneven pad pressure as one or more of the Girling calipers gather bore dirt and the pistons stick. This condition speeds warping. Best to simply replace them. Opinion # 47-2/3 rdsMine measure .471 and .451 they both have very light surface rust and have been parked for 40 years Can they be resurfaced and still be good without issues and should they both be about the same thickness after machining or is one being .020 thicker okay
We’re the new ones you just bought ready to install or did they require turning to true them up ? , I know 50 years ago that was required but new ones these days come ready to install on modern cars Thanks for your response.From my very bad memory, is 1/2" not the new thickness?
A quick google search turned up:
The new rotors are .500 inch and the minimum is .375 inch. The data came
from a factory service bulletin. Hope this helps.
I just bought a pair of new ones from Rick at SS
I do agree that .375 is too thin I am assured that the new ones I have ordered are ready to be installed without any turning required like you had to do way back in the 60s. Thanks you all with advice and suggestionsThe Brakes on Tigers are high up on the Weak points of the car.
.375 is WAY too thin for a Tiger rotor!
Take ANY suggestion to turn them that thin with Block of salt!

I thought so too, but that is what the service bulletin apparently says. Then again I am only as informed as Mr GoogleThe Brakes on Tigers are high up on the Weak points of the car.

Do you even need brake pads if you are using stainless caliper pistons 😮It's amazing that some things aren't in the Sunbeam Specialties catalog. It took Rick a couple of years to add the AC housing.
My advice see how they fade. Get em hot and see what they do. How many panic stops will you make concurrently?
Some good comments would also evolve around what's your favorite brake pad?
