ASE G1 Auto Maintenance and Light RepairSuspension and SteeringMedium
A vehicle exhibits a pull to one side during braking, but not during normal driving. The most likely cause is a fault in which of the following systems?
- ABraking system.
- BWheel alignment.
- CSuspension system.
- DSteering system.
Show answer & explanationAnswer & explanation
Correct answer: A. Braking system.
A pull experienced only during braking strongly indicates an issue within the braking system itself, such as a sticking caliper, restricted brake hose, or contaminated brake pad on one side, causing uneven braking force.
Why the other options are wrong
- B. Incorrect wheel alignment typically causes a pull during normal driving and accelerated tire wear, not solely during braking.
- C. Suspension system issues (e.g., worn bushings) can cause a pull, but often also affect normal driving and handling, not just braking.
- D. Steering system issues usually cause a pull during normal driving or turning, not exclusively during braking.
Brake Pull Diagnosis
A vehicle pulling to one side exclusively during braking is a strong indicator of an issue within the braking system, causing uneven deceleration force.
- Common causes include sticking calipers, restricted brake hoses, or unevenly worn/contaminated pads.
- Requires inspection of brake components on both sides of the affected axle.
- Can lead to premature tire wear and reduced braking effectiveness.
Memory trick: Pull on brake, brake's the culprit.
