Brake at low speed first.
On the traces of rubber on the road, check for the same length of the traces, which indicates the uniform operation of the brakes.
Check the parking brake in the same way.
To test the brakes at higher speeds, a level section of the road is needed.
At a speed of approximately 50 km/h, with the steering wheel released and hands ready to grab it immediately, brake lightly at first and then abruptly to a stop.
If at the same time the car pulls to the left, then one of the brakes on the right wheels is not in order. The car pulls to the side more than the braked wheels.
Let the car roll down a slight slope to see if the wheels roll easily.
After a test drive, try with your hand, is there a difference in the temperature of the rims on different sides of the car? If so, the cause may be stuck brake calipers, heavy play of the rear drum brakes, or defective wheel bearings.
