Has anybody changed out the brake bias spring on an 85 master cylinder? If so, what's involved?

Assuming it is simular to a 96 there isn't all that much too it.

See "My Corvette Pictures" I uploaded a scaned copy of the DRM (http://www.dougrippie.com/) install directions and pictures.

I thought 94,or 95-96 Vettes had the bias spring already installed from the factory,and that its a spring that the tuners found to fit into older C4's that helped in braking balance.Anyone know if there is any truth to this.This is what I read a while back.Sorry to change the subject but it caught attention.Would sux to see later model C4's change out the spring they already have.If im wrong,just let me know the details.Love to know for sure about this stuff.

Yes there is a spring already, but DRM and Mid America sell a spring that adjust more bias to the rear by 7% - 10%. How this spring or any spring affects bias I don't know, but it does.

Strange,I thought the Bias spring they sold was a GM part and came in later model Vettes,wasnt a spring they manufactured on their own.Oh well,either way,sounds like a good mod for the cars.

Correct me if I'm wrong, but isn't that spring for '86 and up? '85s don't have ABS, so the master cylinder's different.
