Would air in the brake lines cause the car to vibrate upon braking from 50mph ish? I was looking under the hood and found the cap to the brake fluid reservoir half way on.
So was the fluid level low? Did most of it splash out?
I would think air in the lines would mean brake failure (i.e. no brake function) and not necessarily any shaking.
There's the right amount of fluid in the reservoir, but air could have gone in the reservoir as well. My brakes aren't failing, just vibration while braking, I'm going to bleed the brakes tomorrow morning.
more than likely the rotors need to be turned. the rotors can develope waves on the braking surface causing the vibration under braking
I hope not, I literally just replaced them this summer. Would that mean my rotors were of low quality? I bought them from rotor pros and read nothing but good things about them.
I think all that will happen with leaving the brake fluid cap loose is moisture getting into the brake fluid, lowering its boiling point if you ever do a lot of hard braking. Id agree it's probably the rotors causing the issue.
Air in the lines would cause the pedal to feel soft and not stop well. Your rotors are warped.... #1 cause of warped rotors is improperly torquing the wheels. It can noticably warp new rotors very quickly.

Do you mean torquing them too hard or not torquing them down properly (star)?
I have had new rotors warp a week after putting them on, something to do with how they were heat treated. They were cheap rotors but after getting them turned they worked well for years.
