used on a Grob Twin II fixed gear which used a Cleveland caliper? Glider made about 1981.
I'm aware of the Dot 3/4 compatible O-ring used in the caliper.

Thanks,

after a couple hours on the computer, I found a listing on an archived Cleveland
application chart, seems to call out;
disk, #164-02601
caliper, #30-63A, But the O-rings have to be changed out to dot 3-4 compatible rings.
linings#066-10500
wheel, #40-97A
