Why does my front end shake when I appy my brakes?

Question

When I apply my brakes on my 1995 Grand-AM, The front end and steering wheel like shake back and forth. And sometimes going at highway speeds, the front end seems to wobble,and shake, like a knot on a tire, or something. But it's really bad when I apply my brakes...What could cause this?

Answer 1

rotors are warped if you get the shake when you hit the brakes and when going at highway speeds you get a vibration it's a bad wheel balance, get the tires balanced on a spin balancer as it will also show if you have a bad tire where a belt has shifted.

Answer 2

Warped rotors caused by somebody tightening the lug nuts with an impact gun with a regular socket and using a torque stick (proper stick that twist at certain torque value). Not using the torque stick, the clamping force is uneven and as the rotor gets hot, it will start to warp. If the clamping force is the same on all 5 lugs, warping of rotors are less likely. From 99 to 02, the Grand Am's, Alero's, and Malibu's were kings on brake pulsation complaints. In 2002, Gm sent a bullention that during the warranty period, the lugs need to be tighten with torque sticks. Since 02, I have seen the brake pulsation complaint drop considerably.

Answer 3

Roters are going to be the problem. You wont be able to turn that out just go buy new ones. I have never had luck when it shakes the wheel that much. You can turn out ones that have a slight vibration. Jack the car up grab the tire and move it see if any play in the steering linkage. Fix what ever has play in it.

13 year old car could have worn ft end parts. First have the brake rotors measured for Minium thickness and discard if to thin...then check if thick enough to resurface RUN OUT warpage and THICKNESS VARIATIONS that feeling just before the car stops like the brakes are being applied unevenly. You may need expensive parts replacement. Only allow good people work on your brakes. Good luck

Answer 5

your previous rotors which you place on are probubly warped. If it replaced into merely executed, it must be the pads seating into the rotors nevertheless. Did you have the rotors became (cut back) which could shelter the vibration. i do no longer know what the noise is yet once you have 2 surfaces that are no longer flat which could make a squeeky noise, vibrations interior the pedal, and or a grindish noise. Your ultimate wager could be to get them appeared at via somebody else, usually it fairly is loose. Worst case call who placed your pads in and tell them your no longer happy with the widely used of there artwork, they could furnish to take a 2d seem at it. it must be the seating of a clean pad on worn rotor. i could have somebody atleast take the wheel off and supply it a great seem. the hot pads is additionally defective. And which could be lined below conflict..

I replaced them

now? smooth as could be

The really important thing is this - there is potentially fatal wear and/or damage to your front end and/or steering and braking components. Get to a repair shop at your earliest convenience before further failure can throw you into a ditch, a tree or an oncoming car!

Answer 8

Warped rotors will cause shimmy while applying brakes.
Wheel balance will cause the shakes while driving

Answer 9

Nothing major here, just take your car in and get the front rotors machined or replaced.
As simple as that.

Answer 10

could be the brake rotors, but my best guess is the cv joints..
they are front wheel drive and will shake for sure
