411 Front Disc Brakes

[peter dowdle]

Kevin I spoke to the local brake specialist who confirmed what you said, it should be stamped on the disc. He made the point that being thinner than the minimum does not create a danger. Years ago a friend restored an Austin Healy 3000 with brand new discs but according to the garage who were doing the roadworthy certificate 1/2 inch discs were not satisfactory. Clearly there is confusion about the regulations.

Seems to me if I have my discs machined and they are not marked how can there be a problem. If I stick with standard disc and use the Cooper Craft calipers I should have adequate stopping power.

I was thinking the same thing. When I went to get a roadworthy on my 411, the tester commented to me verbally that the discs were a bit on the thin side, but that wasn't a failure point.

Personally I believe original braking performance on the 411 is adequate providing the system is in good working order.

The main concern if a car has been standing for a long period of time is rust on the skirt of the caliper pistons.
