What could be the reason for a brake grabbing issue during a test drive?

Worn brake pads
Brake fluid or grease on the brake linings
Overinflated tires
Faulty wheel bearings

The correct answer is: Brake fluid or grease on the brake linings

A brake grabbing issue during a test drive is often caused by brake fluid or grease contaminating the brake linings. When this happens, the friction between the brake pads and the rotor is compromised, which can lead to uneven braking performance. Specifically, if the brake lining becomes contaminated with fluid or grease, it can lead to a decrease in the material’s coefficient of friction. This results in an inconsistent grip on the rotor, causing the brakes to grab or respond inappropriately during application. In contrast, worn brake pads typically lead to a lack of performance or increased stopping distance rather than grabbing. Overinflated tires could affect vehicle handling or ride quality but would not directly cause brake grabbing. Faulty wheel bearings may introduce noise or lead to mechanical failure, but they are not responsible for the grabbing sensation during braking. Thus, the presence of brake fluid or grease on the brake linings is the most direct cause for such braking behavior.
