Brake issues

[bk312312]

Hi guys, got a brake issue that really knocked me for a loop. OK, here goes, I replaced the front rotors, calipers, and pads on the front, and Drums, springs, and pads, in the rear. There were no issues before hand other than they needed to be replaced. Now i have some heavy pulsations when braking from highway speeds and i cant figure out why. everything feels normal when braking from 50 and below. but around 75 braking is causing significant vibrations. i can feel it in the steering wheel and brake pedal. ive exhausted myself figuring this out. any ideas??

Welcome to AF!!

The rotors you put on the car are out of round or warped. It is not unheard of for new rotors not to be properly turned from the factory especially. I know of a gentlemen that put rotors on his Acura and had the same issue. Had them turned and everything was fine. If they are warranted take them back and exchange them for new ones.

thats what i was suspecting. earlier today i realized (like an idiot) i bled them in the wrong order. i went completely reverse. started from the closest to the master cylinder and worked my way out. logic seems to dictate to me that air still trapped in the system would be more of a cushion to those vibrations than anything. could this be a cause of the vibrations or no?? and thatnk you for the welcome. this is the first time ive ever posted a question on a forum. I look forward to adding this resource to my toolbox.

Bleeding the brakes in the wrong order will not cause the symptoms you describe. If they are bled correctly you shouldn't have any issues regardless especially if they are not spongy. I would pull the rotors and have them turned down or take them back for a replacement.
