California DMV Permit Test (Class C)Vehicle Operation and MaintenanceHard
You are driving and notice that your vehicle is consistently pulling to one side when you apply the brakes. What is the most probable cause of this issue?
- AToo much weight in the trunk of the vehicle.
- BAn overinflated tire on one side.
- CUneven wear or malfunction in the braking system on one side.
- DA misaligned steering wheel.
Show answer & explanationAnswer & explanation
Correct answer: C. Uneven wear or malfunction in the braking system on one side.
If a vehicle pulls to one side specifically when braking, it usually indicates an imbalance in the braking force applied to the wheels. This can be caused by a faulty caliper, worn brake pads, air in the brake line, or a seized brake component on one side, causing that wheel to brake harder or softer than the others.
Why the other options are wrong
- A. Excessive weight in the trunk can affect suspension and overall balance but is unlikely to cause a specific pull only when braking.
- B. While tire pressure affects handling, it's less likely to cause a consistent pull only during braking compared to a brake system issue.
- D. A misaligned steering wheel would primarily affect straight-line driving and general handling, not specifically pulling during braking.
Brake Pull Diagnosis
A vehicle pulling to one side specifically during braking indicates an imbalance or malfunction within the braking system, requiring immediate inspection and repair.
- Caused by unequal braking force.
- Common issues: faulty caliper, worn pads, air in line.
- Requires professional brake system diagnosis.
Memory trick: Brake pull means brake fault, get it checked, don't delay.
