Before the vibrating. I changed my front brake pads and rotors then my issue became.
i did some research and I know it’s not my engine mounts or transmission mounts, bleeding the brakes is next but if not, I’m gonna clean the throttle body.
does anyone have been thru this similar problem ? Or give me some tips thanks

 

it vibrates while idling at a stop or while coming to a stop?

 

I think you have a warped brake rotor by your not so accurate description of the issue

While it comes to a stop. It give me a rough idle.

 

Would I have to replace my front disc brakes again ? If there warped ?

 

If you put new rotors on already, they should not be warped. however it is possible they were dropped or something. how long ago did you replace them? warranty? Over tightening the lug nuts or not torquing them to the proper ft lbs can cause them to warp also as well --- overheating them can warp also.

 

Sounds like it's not brake related if it's a rough idle. It could be a lot of things. Did you touch any other part of the engine while doing the brakes?

 

POSSIBLE THAT THERE IS A LEAK IN THE BRAKE BOOSTER WHEN STEPPING ON THE BRAKE------oops sorry for the caps
