Brake effect during normal driving?

Hello.

I guess I've got another "little" problem I could use some help with!

Have the impression that my brakes will slow down with very little pressure during normal driving.
For the test I drove without braking 15 minutes about 130km/h and rolled out into parking lot. See, all rims were equally warm, both front and rear, slightly stronger at the rear. I could not use my finger for more than approx. Tap for one second.

Otherwise, the brakes work perfectly, no ABS lamp and even braking.

(Just "overhapped" my brake caliper at the rear left and new blocks/dishes in and now it works again with the handbrake.)

Question, is this normal or is my braking system spinning? What can that be?

For a tip, I'll be very grateful.

Welcome

Hanno
