What it can mean
Brake torque variation is common, but wheel, tire, hub, steering and suspension faults can feel similar.
What to do next
- Stop driving if braking is reduced, the vehicle pulls sharply, grinding is heard or fluid is leaking.
- Note whether vibration is in the steering wheel, seat or pedal.
- Have braking and wheel components inspected rather than replacing parts by guess.
Possible causes to test
- Brake rotor thickness variation
- Wheel or tire problem
- Loose or worn steering/suspension component
- Normal ABS operation on a low-grip surface
