HiK & KK vs äldre bromsar (Fordon: allmänt)

av Anders_W, Wednesday, December 02, 2020, 20:56 (1629 dagar sedan)

Jag har läst att tryckluftsbromsarna HiK (Hildebrand-Knorr) och KK (Kunze-Knorr) betedde sig som ett mellanting mellan de äldre enkammarbromsarna och de nyare tvåkammarbromsarna.

Är någon på forumet bekant med vari skillnaden mot äldre enkammarbromsar låg?
