The brake place says they need to be replaced, but they look almost new.
The VSPER concept says that electrons will attempt to get as a protracted way removed from different electrons as possiblepoor costs do no longer love diverse undesirable feesthe terrific way I draw a Lewis shape is by ability of ability of first drawing the guy atoms with the electrons around themI then artwork out what number electrons each and every atom desires to get to realize a noble gas configurationas an example, C desires 4I then seem on the bonded atoms at combine the electrons to make bondsIn CO2, the C desires 4 and the O desires 2A drawing might appear like: :O: :C: :O: The 8 electrons in C and O can combine to make 4 bondsThere may well be 2 double bonds: :O C O: The lone pairs that are left over make each and every O atom polarthose are at the instant opposite, so as that they cancel another out and the molecule is independentdetermine your diagram by ability of utilising inclusive of each and every of the valence electrons assigned to each atom (given by utilising the artwork rigidity they're in) and seeing if that's a similar as a results of fact the quantity of electrons you drew (a million bond 2 electrons)A + or - sign next to a molecule shows that the molecule has a costElectrons have a poor valueThe + shows that an elctron was once lost, making the molecule extra usefulThe - ability that an electron become won, giving the molecule a extra physically powerful poor value.
Sounds like typical heat stressNew brake materials are a mixture of ceramics and other compounds to resist brake failure due to excess heatThis is why most brake pads have little dams and valleys around some areasThey act as thermal reliefsIf the cracks are very small, I wouldn't worryBut if they are large and deep, you may want to replace the pads.
