Q: Pulls left when brake apleyed have replaced ho front brakes calipers and lines still pulls left no air in sistom

I would need to know if the ABS or Check Engine Light is on? If it is, then it needs to be addressed to see if anything is causing the ABS control to engage and cause the pull for some reason.

如果没有灯打开，我会说检查何时缓慢行驶并轻轻触摸制动器，以查看它是否向左拉动。如果在轻刹车过程中拉动，则需要检查右前制动卡钳和橡胶软管，并检查左后制动器是否有相同的东西。

The rubber hose may be damaged internally and little or no pressure can pass to the caliper. This can be checked by bleeding the brakes and if little or no pressure gets through the right caliper then suspect a bad brake line on the passenger side front. A certified mechanic from YourMechanic candiagnose why your car is pulling to the left并确保进行正确的维修。
