Idle set too high or accelerator is sticking and needs lubrication.
If the brakes are too loose that could be a result.
The friction caused by the brakes causes the car to decelerate. This negative acceleration, in turn, causes a force to be applied to all those in the car. This is the lurch you feel.
It is possible it is one of the speed sensors.
A repair shop can release a car with bad brakes if they were not asked to repair the brakes or the customer refused service. It is then the responsibility of the customer to have them repaired.
Weight transfer. When a car brakes, its weight moves forward and causes the front brakes to do the majority of the work in stopping the car.
You could have worn out shocks or stuts
There are a few causes to whining brakes in a car. One reason could be that the caliper is out, and another could be that the pad is worn out.
Friction causes the heat.
Assuming you are not pressing down on the gas, when you release the pedal, the car will slow down over time and evetualy come to a stop. Unless you are going down a hill, in which case you will speed up.
When there are any issues with your brakes it is best to take your car in to a certified mechanic. Brakes can knock for several reasons, including the calipers, brake pads, and bearings.
The force of friction between the tires and the road surface is what primarily causes a car to stop. When the brakes are applied, the brake pads press against the rotating wheels, generating friction that slows down the car.
because the alignment is off Warped or out of round brake rotors/drums.
