Possibly a rotor scored badly or warped from overheating, maybe a piston that's sticking. Either way, essential to strip the front brakes and check everything.
not usually. warped rotors will cause a vibration during braking.
The shuddering could be caused by several things. Check the front end parts on the Fiesta to start with. A loose or worn part is the most likely cause of the problem.
Your rotors are probably warped from getting hot during braking and need to be "turned" or replaced. I suggest you take it to a brake shop or dealer.
warped rotor
replace front brake rotors and pads.
My first guess would be the front end alignment and possibly the brakes. During braking, you engine and transmission are not under a load so they should not cause any vibration.
When a front differential goes bad, you may notice symptoms such as loud noises coming from the front end, difficulty steering, vibrations, or the vehicle may feel like it's slipping or shuddering during turns. It is important to address these issues promptly to avoid further damage to the drivetrain.

realignment, 60 to 80 bucks
Get you front end aligned, that should take care of the shakes.
Yes, a brake caliper can cause the front end to shake when the brakes are applied. If a caliper is sticking or not functioning properly, it can lead to uneven braking pressure, causing vibrations. Additionally, if the brake pads are worn unevenly due to a malfunctioning caliper, it can result in a pulsating sensation during braking. Regular inspection and maintenance can help identify and resolve these issues.
the brake rotars are out of round or warped.have them machined
