Ar an dara dul síos, tar éis na pillíní coscáin a athrú, déan iarracht gan cosc ​​a chur ar chosa móra, gan trácht ar choscán géar. Toisc nach bhfuil dromchla cuimilte na bpillíní coscáin nua comhoiriúnach go hiomlán le dromchla an diosca coscáin.

Mar sin, cén fáth a roghnaíonn samhlacha ardfheidhmíochta dioscaí agus pillíní coscáin ar mhéid mór? The more reasonable explanation is that the increase of the contact area is conducive to heat dissipation and reduce the thermal attenuation effect when braking. Thairis sin, má tá an ceap coscáin beag, is furasta é a chuimilt an -tanaí, má tá an ceap coscáin mór, cuirfidh sé moill ar an am tanaithe.

The so-called thermal attenuation refers to that when braking vigorously, due to the intense friction between the brake pad and the brake disc, the friction material of the brake pad is softened by thermal expansion, and the friction coefficient is reduced, thus affecting the Feidhmíocht coscánaithe.

In general, after the new brake pads are replaced, it is necessary to fully run in at least 500km to allow the new brake pads to enter the best working condition. Before this, the speed should be properly controlled, and the road condition should be predicted at the high speed to prevent sudden braking and affect the braking force. I mbáisteach agus i aimsir sneachta, ba cheart dúinn níos mó airde a thabhairt ar an gcoscán a thuiscint agus an fad a choinneáil.
