Txhawm rau txiav txim siab seb lub nres nres (rotor) xav tau kev hloov pauv, xav txog cov cim hauv qab no:
Pom Kev Hnav thiab Thickness- Ntsuas tus nres disc thickness siv lub caliper. Yog hais tias nws tau hnav hauv qab qhov chaw tsim khoom qhov tsawg kawg nkaus thickness specification, nws yuav tsum tau hloov.
Sib sib zog nqus Grooves lossis Scoring- Sib sib zog nqus khawb los yog grooves ntawm lub disc nto tuaj yeem txo qis kev ua haujlwm ntawm braking thiab qhia tias yuav tsum tau hloov.
Kev vibration los yog co- Yog tias koj xav tias muaj kev vibrations lossis pulsations hauv lub kauj tsheb lossis nres pedal thaum nres, cov discs yuav raug hloov thiab yuav tsum tau hloov.
Hnav tsis sib xws- Yog tias ib sab ntawm disc hnav ntau dua li lwm qhov, nws tuaj yeem qhia txog cov teeb meem caliper thiab yuav tsum tau hloov lub disc.
Squealing los yog sib tsoo suab nrov- Cov suab nrov txawv txav thaum braking tuaj yeem qhia qhov hnav ntau dhau los yog kev puas tsuaj rau qhov chaw disc.
Thaum tshav kub kub los yog Discoloration- Cov pob xiav lossis tsaus nti ntawm lub disc qhia tias muaj cua sov, uas tuaj yeem cuam tshuam kev ua haujlwm braking thiab yuav tsum tau hloov.
Txo Braking Performance- Yog tias qhov kev ncua deb nce lossis nres nres tsis muaj zog, cov discs yuav raug hnav thiab yuav tsum tau kuaj xyuas.
Kev tshuaj xyuas tsis tu ncua thiab hloov raws sij hawm ntawm cov nres discs kom paub meej tias kev ua haujlwm braking zoo thiab kev nyab xeeb ntawm kev tsav tsheb.
