This may be caused by an alignment issue with the wheels. here are some things you can do to test your suspicions:
if it is indeed your front-end alignment, try to feel for any unusual binding in the steering wheel while turning corners or points where you accelerate. you may also want to take some turns without braking so that at least one set of tires has an equal chance of creating a wobble while accelerating, but keep in mind this won't necessarily tell you what's wrong if all four sets didn't wobble when braking. if there is no binding in the steering wheel after testing with straight driving, then it could be one of two front-end problems which are both relatively costly repairs depending on how badly damaged
why does my car wobble when i brake?
if your car is making a shuddering noise when you brake, the stiffness of your brake pads may be too high.
stiffness, or more simply resistance to moving, in this context most often leads to the noise. make sure that they are not coming into contact with the metal drums when placed against them. also make sure that they are worn down enough so that you can see their “teeth”.
is it bad if my car shakes when i brake?
you are braking too hard. when you brake, keep constant pressure on the breaks to avoid having the car jump one way or another.
why is my car shaking when i brake at high speeds?
the shaking comes from a design flaw in the manufacturers' assembly of a metal-on-metal friction system. the sound is not dangerous, but it probably means that your car's brakes will begin to wear down very quickly. to remedy this problem, you should have the brake pads checked and replaced by an automotive technician. in other words, it sounds like your emissions system needs repairs! 🙂
i hope you found this helpful! i'm sure someone else has been wondering about that too 😉
can bad alignment cause wobble when braking?
yes, bad alignment can cause wobble when braking.
the four major problems that could cause brake wobble or what we call “brake judder” are the brake pads and the rotors not lining up correctly with each other, a bent rotor which isn't caused by an accident but from neglect due to lack of routine care (including belt replacement), an uneven tire wear pattern on the v-shaped pad edges that's asymmetric by at least one millimeter based on worn out, close-to-reaching end status; and finally a warped disc rotor which has been damaged from improper storage and excessive heat and/or pressure.
