yes its fine.
all of the wheels used to get locked.
so got a full brake check up.
fisrtly the mechanic changed the fliud without opening the cylinder.the problem prevailed after the test run.
the problem was in the cylinder.
after cleaning the cylinder and changin the fliud the problem was gone.
can mobil oil get mixed up with braking fliud.
the car was running fine ,no problem with the brakes no locking up.
but this problem came again after 6 months.
