Disc brakes: Pehea lākou e hana ai?

I ka makahiki 1917, ua hana kekahi mechanic i ke ano hou o na kaa i hoohana ia hydraulically.ʻElua mau makahiki ma hope mai ua hoʻomaikaʻi ʻo ia i kāna hoʻolālā a hoʻolauna i ka ʻōnaehana hydraulic brake hou.ʻOiai ʻaʻole i hilinaʻi ʻia mai nā mea āpau ma muli o nā pilikia me ke kaʻina hana, ua lawe ʻia i ka ʻoihana automotive me kekahi mau loli.

I kēia mau lā, ma muli o ka holomua o nā mea a me ka hoʻomaikaʻi ʻana i ka hana ʻana, ʻoi aku ka maikaʻi a me ka hilinaʻi o nā disc brakes.ʻO ka hapa nui o nā kaʻa hou he ʻehā huila kaʻa, hoʻohana ʻia e kahi ʻōnaehana hydraulic.Hiki iā ia ke disk a pahu paha, akā no ka mea, ʻoi aku ka nui o ke kaʻa ma mua kahi e pāʻani ai nā kaʻa, ʻo ke kaʻa ʻaʻohe pāʻani disc i mua.No ke aha mai?No ka mea, i ka wā o ka hoʻopaʻa ʻana, hāʻule ke kaumaha o ke kaʻa i mua a, no laila, ma nā huila mua.

E like me ka hapa nui o nā ʻāpana i hoʻokumu ʻia ai ke kaʻa, ʻo ka ʻōnaehana braking kahi mīkini i hana ʻia i nā ʻāpana he nui i mea e hana pono ai ka hoʻonohonoho.ʻO nā mea nui i loko o kahi disk brake:

Pills: Aia lākou i loko o ka puʻupuʻu ma nā ʻaoʻao ʻelua o ka diski i hiki iā lākou ke paheʻe ma hope, i ka disc a neʻe aku mai laila.Aia i loko o kahi pahu pahu kahi pila o nā mea hoʻoheheʻe i hoʻoheheʻe ʻia i kahi pā hoʻihoʻi metala.I ka nui o nā pad brake, hoʻopili ʻia nā kāmaʻa hoʻohaʻahaʻa walaʻau i ka pā.Inā ʻaʻahu ʻia kekahi o ia mau mea a kokoke paha i kēlā palena, a i ʻole he pōʻino, pono e hoʻololi ʻia nā axis a pau.

Tweezers: i loko o laila ka piston e kaomi ana i nā pila.ʻElua: paʻa a lana.ʻO ka mea mua, hoʻokomo pinepine ʻia i nā kaʻa haʻuki a me nā kaʻa nani.ʻO ka hapa nui o nā kaʻa e kaapuni nei i kēia lā, aia nā ʻōpiʻi pahu lana, a ʻaneʻane loaʻa i hoʻokahi a ʻelua paha piston ma loko.ʻO nā compacts a me SUV ka mea maʻamau he piston tweezers, ʻoiai nā SUV a me nā kaʻa nui he pālua piston tweezers i mua a me kahi piston ma hope.

Discs: Kau ʻia lākou ma luna o ka bushing a huli i ka huila i ka huila.I ka wā hoʻomaha, lilo ka ikehu kinetic o ke kaʻa i ka wela ma muli o ka paio ma waena o nā pila a me ka disc.No ka hoʻopau maikaʻi ʻana, ʻo ka hapa nui o nā kaʻa i hoʻokuʻu ʻia i nā discs ma nā huila mua.Hoʻohana ʻia nā disks hope i hoʻoheheʻe ʻia i ka mea kaumaha loa, ʻoiai ʻo ka mea liʻiliʻi loa i nā disks paʻa (ʻaʻole i hoʻoheheʻe ʻia).
