brake pedal and car slight vibrates when pressed

[quote:633c31bacb="liltapper21"]when the brake pedal is pressed. you can feel the whole car shudder... not violently. but enough to notice it.. you can feel it in the pedal too.. ive replaced both rotors.. the right rotor twice! the right caliper froze up twice which wore the brake pads on the right down to nothing and grinded the rotor. so i replaced all the components. the first time i had replaced it i replaced the brake hose. i belive the back right drum is rubbing on a brake. maybe its warped or something odd inside. but i dont know if it would cause it to vibrate and shudder... it happens more when you brake at a higher speed. maybe 45 and higher... you dont feel it braking much at a slower speed. any ideas on what it could be, or suggestions what to look at i havent already. i greatly appreciate it.[/quote:633c31bacb]

Been here before with warped rotor/s mike it and check its out of roundness/parallelism.

ive replaced both rotors, one of them twice.. how do they go warped in a matter of days ,after i replaced them.. they probably are warped... can drums do this too the vibrating. or just rotors? cuz i beleive one drum is warped or uneven. inside.. i am going to go check them out again, but what do you mean by mike it? thanks

Miking it is checking its thickness-then use a dial indicator.

Drums you need a brake gauge to determine its wear-out of specs-could me replacement and /or resurfacing it.

Good Luck

okay i checked all the front two side. the rotors for thickness which iwas in range and check for warpness. didnt find any at that , i check the calipers for movement , or frozen and brake pads. greased everything.. all seems to slide okay... air bled out... i didnt get to look at the drums yet again.. . but after i looked and greased up the front. i took it out. and it still vibrates to a point. i dont think its as bad, but might be my imagination... the pedal still pulsates.. some.. and it still shudders when you brake at higher speed..... sometimes the steering vibrates too.... could it be a tire out of balance or steering or . i still need to look at the drums ? im sure anything can do it, but what would you recommend i look at next? i really need to figure this out... i apreciate any help thanks!!

Go check what's happening on the back this will conclude the brake system. Then we'll think! about wheel alignment/suspension
