The wear of friction pair is the main reason for the deterioration of braking state. Jagorar da ke aiki a cikin hanyar mai ƙarfi ta dace, da asarar kayan da rikici a rarrabe sannu a hankali yana ƙaruwa da karuwar amfanin amfani. Lokacin da sayawar ta tara zuwa wani gwargwado, sigogi na halayyar dan adam sau biyu a sannu a hankali canza kuma ana rage karfin aiki. The wear of other matching parts also affects the wear of friction pairs. Misali, rashin daidaituwa na birki na birki yana shafar ɗalibin garin, wanda kuma ya shafi gudun hijira har sai ya shafi lambar tsakanin kayan masarufi da biyu.

Wear depends on the conditions of friction and the state of friction. Abubuwan da aka ƙarfafawa galibi suna cikin nau'in bushewar bushe, kuma wannan yanayin tashin hankali ba tare da mummunan yanayin ba, wanda zai zama babu makawa ga suttura da haɓaka rata mai dacewa, kuma yana shafar aikin yisti. Kuma a karkashin yanayi na yau da kullun, wanda ke sa bangaren tashin hankali ya zama mara nauyi, kuma sanya rake da rata shi ne kuma mara kyau, wanda ya shahara a kan birki. The non-uniformity of friction changes the distribution of brake pressure and increases the non-uniform wear of friction pairs. Bugu da kari, masanan dumama na aikin braking da kuma ƙura na yanayin aiki a cikin 'yantar da tuki, da kuma sa sawa a lokaci guda, wato, sakin shi ba makawa. Koyaya, adadin da saurin sutura za a iya sarrafa shi, saboda saurin sa ya dogara da lamba da kuma yawan amfani, ƙarfin amfani da, amfani da yanayin amfani.
