Default One rotor replaced.

Should I have replaced both? I now have a wobble at 60+ that I cant explain with tire pressur. And yes I didnt have the old one turned. Are these cars prone to some wobble?

Question in my mind would be, why did you replace a rotor?

Yes, best to replace both at same time, I'm not a mechanic but I thought replacing one would be a big No No

It'* not the normal practice. however each caliper and rotor does work independently.

For consistency of braking etc, replacing both at the same time is recommmended.

However..depending on miles, same brand etc...you could do one w/o worries.

No, these cars are not prone to wobble, lol.

In fact, the opposite is true. Mine is smooth as silk when I have all systems maintained.

Also, you mention a wobble at 60 mph. Is that when you apply the brakes? Because if it'* happening when the brakes are not applied, you need to look further.

What type of wobble?

It could be an out of balance tire or a tire with internal belts letting go.

Alignment issues?

Please give us a little more info to go on.

Confession time. Ive been so broke during school I waited to long to change the brake pads. One side was munched the other was, or looked fine. So I replaced the bad side and the pads( on both sides). It wold of cost another 25 bucks and I didnt have it at the time. ( for the Rotor)

Hmm... Not with brakes... Just a shake. Like a tire out of balance I guess. The tires are old, but still seem to have good tread.

Ok another thing. I have no clue as to what to run my tire pressure at. I run it at 40 right now. I can't figure out what the side of the tire is telling me.

Im going to go get my son Ill read the stuff and bring it in.

I would look for sign'* of cupping on the tire too. I didn't get mine rotated in time and it was a little low on pressure and it cupped. You can feel a little wobble but it is very faint.
