omillarga bog&#039;liq bo&#039;lishi mumkin:<\/p>\n\n\n\n<ul>\n<li>Eskirish va yirtilish: Tez-tez ishlatish pinlar, igna teshiklari va tormoz kolodkalari kabi komponentlarning a\u015f\u0131nmas\u0131na olib kelishi mumkin, bu esa tormoz qo&#039;lining holatida o&#039;zgarishlarga va tormozlash momentining pasayishiga olib keladi.<\/li>\n\n\n\n<li>Prujina muammolari: Zaif yoki noto&#039;g&#039;ri sozlangan asosiy prujinalar tormoz kuchini kamaytiradi, ko&#039;pincha material sifatining pastligi yoki charchoq tufayli.<\/li>\n\n\n\n<li>Noto&#039;g&#039;ri joylashuv: Tormoz g&#039;ildiragining radial noto&#039;g&#039;ri joylashuvi eksantriklikka olib kelishi mumkin, bu esa tormozlash samaradorligining pasayishiga olib keladi.<\/li>\n\n\n\n<li>Notekis yostiqcha oralig&#039;i: Tormoz yostiqchalari va tormoz g&#039;ildiragi orasidagi notekis aloqa momentni pasaytiradi, ko&#039;pincha o&#039;rnatishdagi noaniqliklar yoki bo&#039;shashgan murvatlar tufayli.<\/li>\n\n\n\n<li>Uzoq zarbali tormozlar tiqilib qolgan: Qarama-qarshi og&#039;irlik ostidagi tayanch material tormoz momentini kamaytirishi mumkin.<\/li>\n<\/ul>\n\n\n\n<p><strong>To&#039;liq bo&#039;lmagan tormozlash uchun yechimlar<\/strong><\/p>\n\n\n\n<p>Ishonchli tormozlashni tiklash uchun quyidagi amallar tavsiya etiladi:<\/p>\n\n\n\n<ul>\n<li>Eskirgan tormoz qismlarini almashtiring va har qanday to&#039;siqlarni olib tashlang.<\/li>\n\n\n\n<li>Ifloslantiruvchi moddalarni olib tashlash uchun tormoz g&#039;ildiragi va prokladkalarini kerosin yoki benzin bilan tozalang.<\/li>\n\n\n\n<li>Noto&#039;g&#039;ri hizalangan tormoz g&#039;ildiraklarini qayta tekislang yoki almashtiring.<\/li>\n\n\n\n<li>Yostiqchalar orasidagi masofani bir tekisda saqlash uchun vintlar va yordamchi prujinalarni sozlang.<\/li>\n\n\n\n<li>To&#039;g&#039;ri hizalanishni ta&#039;minlash uchun tormozlarni aniqlik bilan qayta o&#039;rnating va qarshi og&#039;irliklar ostida qo&#039;shimcha tayanchlarni olib tashlang.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\"
