Discurile de fr\u00e2n\u0103 se deformeaz\u0103 la un moment dat din diverse motive. La fel ca celelalte piese auto, \u0219i acestea se deterioreaz\u0103 \u00een timp, \u00eentruc\u00e2t apar zone neuniforme pe suprafa\u021ba loc, iar modific\u0103rile care survin vor avea un impact asupra modului \u00een care fr\u00e2neaz\u0103 ma\u0219in\u0103.<\/p>\n\n\n\n

C\u00e2nd se deformeaz\u0103, procesul de fr\u00e2nare va fi mai pu\u021bin eficient, iar acest lucru poate pune \u00een pericol siguran\u021b\u0103 pasagerilor \u0219i \u0219oferului.<\/p>\n\n\n\n

De ce apar deform\u0103ri ale discurilor de fr\u00e2n\u0103?<\/h3>\n\n\n\n

Materialul din care sunt realizate discurile de fr\u00e2n\u0103 este unul foarte rezistent. Cu toate acestea, pot s\u0103 apar\u0103 anumite nereguli, iar cea care le afecteaz\u0103 \u00een acest caz este c\u0103ldur\u0103. Atunci c\u00e2nd pedala de fr\u00e2n\u0103 este folosit\u0103 \u00een exces, componentele se supra\u00eenc\u0103lzesc.<\/p>\n\n\n\n

Pe de alt\u0103 parte, dac\u0103 pl\u0103cu\u021bele de fr\u00e2n\u0103 sunt uzate sau au calitate slab\u0103 exist\u0103 un risc crescut de deformare. O alt\u0103 cauz\u0103 este vitez\u0103 crescut\u0103 cu care circul\u0103 mul\u021bi \u0219oferi, \u0219i fr\u00e2narea brusc\u0103. \u00cen astfel de cazuri, pl\u0103cu\u021bele de fr\u00e2n\u0103 se \u00eenc\u0103lzesc, anumite componente se \u00eenmoaie \u0219i ajung \u00een spa\u021biul dintre pl\u0103cu\u021b\u0103 \u0219i disc<\/a>.<\/p>\n\n\n\n

Se poate evita deformarea discurilor de fr\u00e2n\u0103?<\/h3>\n\n\n\n

Dac\u0103 ve\u021bi circul\u0103 pe o pant\u0103 de rulare descenden\u021ba este indicat s\u0103 controla\u021bi vitez\u0103 ma\u0219inii prin trecerea acesteia \u00eentr-o treapt\u0103 de vitez\u0103 inferioar\u0103.<\/p>\n\n\n\n

Dac\u0103 discurile de fr\u00e2n\u0103 sunt deformate se vor auzi zgomote sub form\u0103 unor sc\u00e2r\u021b\u00e2ituri, precum \u0219i miros de cauciuc ars. Mai mult, dac\u0103 fr\u00e2narea se va realiza cu \u00eentreruperi dese \u0219i apar vibra\u021bii \u00een momentul ma\u0219inii, aceste lucru \u00eenseamn\u0103 c\u0103 discurile sunt deformate.<\/p>\n\n\n\n

Care sunt semnele care arat\u0103 c\u0103 fr\u00e2nele vor ceda<\/h3>\n\n\n\n

Un indiciu care v\u0103 indic\u0103 uzura pl\u0103cu\u0163elor de fr\u00e2n\u0103 \u00eel reprezint\u0103 canalul de pe mijlocul pl\u0103cu\u0163ei. Dac\u0103 canalul nu mai este pronun\u0163at, este evident c\u0103 pl\u0103cu\u0163ele trebuie schimbate. Performan\u0163\u0103 slab\u0103 de fr\u00e2nare sau cursa moale a pedalei. \u00cen acest caz probabil lichidul s-a scurs din sistem. Asta denot\u0103 o problem\u0103 mai grav\u0103 care cere schimbarea complet\u0103 a sistemului. Ajuns \u00een acest punct ma\u015fina nu mai poate fi transportat\u0103 pe ro\u0163ile ei p\u00e2n\u0103 la cel mai apropiat service;<\/p>\n\n\n\n

Sc\u00e2r\u0163\u00e2it sau huruit<\/a>\u00a0\u00een timpul fr\u00e2n\u0103rii. Acestea pot anun\u0163a uzarea pl\u0103cu\u0163elor sau blocarea pistonului de etrier.\u00a0Dac\u0103 ma\u015fina \u201etrage\u201d \u00eentr-o parte \u00eenseamn\u0103 c\u0103 pl\u0103cu\u0163ele de fr\u00e2n\u0103 fie au fost contaminate cu ulei sau cu vaselina, fr\u00e2narea fiind ineficienta la respectiva roat\u0103, fie etrierul s-a blocat.<\/p>\n\n\n\n
