Warped rotors
not usually. warped rotors will cause a vibration during braking.
vibrations while slowing or braking? Get the front brake rotors checked.
This is a self-exited vibration problem.
Balance your tires!
The brake rotors are warped. Someone tightened the lugnuts out of sequence. That compressed and torqued the rotors out of spec. Replace the from rotors and pads and the rear ones too, if necessary.
Wheel bearings are the most common for causing a vibration.
Front brake shudder in a 1995 Mercury Villager can be caused by several factors, including warped brake rotors, uneven wear on brake pads, or issues with the brake calipers. Warped rotors can lead to inconsistent contact with the pads, causing vibration during braking. Additionally, if the brake pads are worn unevenly or not properly installed, this can contribute to shuddering. Regular inspection and maintenance of the braking system can help identify and resolve these issues.
Your rotors may be warped. They key need to be refinished or replaced.
What percent of braking are front wheels responsible
Yes, a loose front wheel bearing can cause shuddering when braking. When the wheel bearing is worn or improperly tightened, it can lead to excessive play in the wheel, causing the brake rotor to move unevenly. This uneven surface can result in vibration or shuddering during braking. It's important to address this issue promptly, as it can affect vehicle safety and handling.
The braking problem is almost certainly a disk brake rotor. The vibration could be a faulty tire, a bent or damaged "half shaft" or an out of balance tire. Front end vibration is not caused by an alignment problem, but can be accentuated by worn suspension or steering components.
