If your car pulls to one side when you press the brakes while you are driving, this means that there is a problem with the moving part of your vehicle. So why does the car pull to the right or left when it hits the brakes?
Cars need to go in a straight line while driving and braking. When you brake in your vehicle, seeing it go to one side means that the vehicle pulls.
The way to understand what the car is pulling is very simple. Release the steering wheel while cruising without accelerating too much. Start braking slowly. If the car is going to one side on its own, it’s called pulling.
If your vehicle pulls to one side when it presses the brakes, this is a harbinger of a malfunction.
Reasons to Pull Right or Left When Pressing the Brake
1- Brake Calipers
There are pads inside the brake caliper. If one of the calipers fails, it cannot print on the disk. When you brake in your vehicle, it means that the braking system on the towing side is working.
2- Irregular Wear of Linings
The brake pads squeeze the discs so that the car can stop. This tightening process must be of the same power in the wheels on both sides. However, if one side’s brake pad runs out more quickly, it causes the car to pull to the right or left.
3- Suspension Failures
A ruptured shock absorber, tie rod or suspension malfunctions can cause your vehicle to pull to one side when you press the brakes.
