I'll get to the point. Every time I brake my car wobbles. I've had the rear rotors fixed and replaced a front wheel bearing. I know next to nothing about cars; I unknowingly bought a lemon for reasons that are irrelevant and have now paid more in repairs than the car. Why? Because, apparently, I am a dumb. Now, the car doesn't shake when driving, in reverse, etc., just when I brake. Is this a tie rod issue? Stabilizer link? Any help is appreciated. Let me know if you need further car details.

First of all, what do you mean by "wobbles?" Are you talking about a pulsing sensation in the brake pedal (and maybe the steering), is the car trying to dive all over the road, is it pitching like a boat in rough water, or what? Have you had the front rotors checked, resurfaced, or replaced? That's probably the first place I'd look.

1500quidporsche posted:have the front rotors machined. Rotors are so loving cheap that no one machines them any more. Unless you are a huge poor, you can afford 14 dollar a side rotors. Shaking under braking is most certainly warped brake rotors. Do front rotors and pads and if your caliper setup has slides make sure they move freely. I don't know how poo poo works unless it's on a 15 year old poo poo box subaru.

Yeah, it has sort of a pulsing sensation. Doesn't do that when driving at low speeds, just anything above 40mph.

hosed rotors, and likely hosed guide pins on your calipers. take the poo poo apart and grease the pins with the right grease and get some shithouse quality rotors on it. that'll cure your issues.

Slow is Fast posted:Rotors are so loving cheap that no one machines them any more The guy who owns the shop we use for cabs tests and machines basically every rotor he comes across. He swears every rotor on earth comes from the factory out of spec unless its some crazy high end poo poo. He pulled a brand new rotor for one of our Rav4s out of the box and put it on the lathe for demonstration. Sure enough that poo poo was off ever so slightly, so he cleaned it up before it went on. I mean it makes perfect sense that some factory in bumfuck china's tooling isn't perfect

First brake rotors. While they're being changed, check (or have your mechanic check) for any play in suspension or steering joints. If it's still doing it after getting the ok on both, get the alignment checked.

GM-bashing/'they were all lemons' jokes aside it's pretty standard for any vehicle of that age to need a bunch of work, and doubly so for a '90s General. If you like the car enough to keep it just bear in mind you're going to be throwing some money at it on a somewhat regular basis. That said, warped rotors and/or some front end work is not a particularly big deal.

Also front brakes rotors being too small for the car is a common problem, manufacturers cost cutting usually means sourcing stuff like brakes from whatever was avaliable, which was usually the smaller previous generation. You haven't bought a lemon, you've just bought a 90s car.

ultimateforce posted:"I bought a cheap used car, what do you mean it requires maintenance?" - Every AI question thread To be fair I think everybody goes through that stage of car buying. Eventually they either buck up and learn to do the maintenance or learn that they need to spend a bit more to get a car that doesn't need work.

Update: rotor, ceramic pad issue, as all of you suggested. Fixed now, though my silent rage run neath over having to purge my wallet these last few weeks. (Apparently I also have an antifreeze leak that torrents right onto my starter. Moral of the day: don't be a dumb and be patient when buying a car from a private owner. Also bring a mechanic along with you)

I knew before buying the car there would be necessary repairs, just didn't expect to purge my wallet so quickly. Thanks for all the feedback.

You haven't bought a lemon, you've just bought a 90s car. 90's GM sedans were loving terrible for this. Pontiac Grand Prix I'm looking at you with your tiny rear end rotors and massive front brake bias.
