2001 Ford F-250 Super Duty Question: Brakes - Calipers

When I press the brake with my foot....About 1/2 way through the deceleration process I hear a loud thump noise from my front left wheel...I dont hear the every time I brake....Is it a defective caliper or rotor....? -
Answer 1
You might have a loose caliper on that side or your pad has become delaminated from its backing, Better get this checked right away -
Answer 2
You know I had the same problem and was told it was the power booster. sooo I changed that and still had the same problem. I've been told it is the power steering pump so that is the next to be changed. If you pop the hood and listen underthe hood or brakes have someone press them and you can find the vibration. -
Answer 3
Check left front ball joints. -
Answer 4
Ball joints fixed mine. Front right was my culprit. -
Answer 5
I had the same problem. There is a vacuum hose going to the brake caliper. Check to make sure it is on. I repaced this hose and the thump disappeared. -
