Kev txhim kho cov ntaub qhwv tshiab rau ntawm qhov qub, hnav tsis sib xws tuaj yeem ua rau cov brakes kub heev thaum thawj theem ntawm kev siv. Qhov no yog vim qhov kev sib txhuam tas li ntawm cov ntaub qhwv ntawm lub disc.

Nws tseem pom zoo kom tig cov discs yog tias lub disc yog xeb. Thov nco ntsoov tias tom qab tig, lub thickness yuav tsum siab tshaj qhov tsawg kawg nkaus, thiab saum npoo yuav tsum tau pitted. Thickness Cov khoom uas peb tuaj yeem sau tau me me, yog li kev ua haujlwm zoo li no tsis tshua muaj peev xwm ua tau hauv kev xyaum.

Disks nrog kev khiav ntawm 50 km, piv txwv li, muaj qhov tsis sib xws thiab hnav zoo heev uas tom qab dov nws peb yuav tsis tau txais qhov tsawg kawg nkaus.

Ib qho kev puas tsuaj rau cov discs yog lawv curvature (twisting).

Txawm li cas los xij, cov ntaub thaiv zoo li no tuaj yeem kho tau zoo. Nws yog txaus rau dov lawv, nyiam dua yam tsis muaj disassembling lawv. Qhov kev pabcuam no yog me ntsis kim dua (PLN 100-150 rau ob lub log) dua li classic tig ntawm lub tshuab dhos, tab sis muab rau peb 100% kev ntseeg siab tias peb yuav tshem tawm qhov kev khiav tawm. Tsis tas li ntawd, hauv qee lub tsheb, disk disassembly yog kim thiab siv sij hawm, vim nws yuav tsum tau tshem tawm tag nrho cov kev ncua.

Hmoov zoo, nyob rau hauv ntau lub tsheb, hloov cov brakes yog ib qho yooj yim heev thiab siv sij hawm me ntsis ntau dua li hloov cov ntaub qhwv. Tus nqi ntawm kev hloov cov discs nrog cov ntaub qhwv yog li ntawm PLN 80 txog PLN 150. Shield nqi sib txawv heev.
