When braking, most of the time my car shakes heavily when braking. What would be the MAIN causes of this?

 

"warped" rotors

 

Yeah I thought it would be that but replaced that with the brake pads. Noticed a lil' difference. Any other areas?

 

Tie-rods, ball joints check for slop. Jack your car up and wiggle stuff in the front end steering/suspension stuff. Did you have your rotors resurfaced or replaced when you got your brakes done?

 

I did rotors then brakes.

 

My car was doing the same thing, shaking during heavy braking, usually above 60 mph or so, and it turned out one of my front tires was bad. I got new tires and the problem disappeared.

 

tire out of balance by a little bit like stated above

 

air in your brake-lines. Bleed them and bleed your ABS reservior* (if equiped and IF bleedable).

 

make sure your lug nuts are all torqued properly

 

there is no such thing as warped rotors

your pads were not broken in correctly, unevenly distributing pad material on rotor surface

Yeah the tires are new, and I got the lugs on just right after I put on the brake pads. But I probably need to bleed the brakes, haven't tried that. Anything else to check before performing these tasks?

 

No this happened before I got the pads, thats why I bought the new pads. I broke them in with patience as well.

 

my car is doin the same thing, but probably for a different reason, my d.s. axle is too long cuz i did an oddball swap and didnt get a custom axle yet, so as a result of that me wheel bearing is shot...i mean shot! so check your wheel bearing too...you can do that by jacking up the front end and shaking the wheel top to bottom (put one hand on top and one hand on the bottom, then shake). If there is any play you need a new bearing. If that is the case i would go ahead and get the hub right away too. You can get the parts pretty cheap through AC-Delco

 

LMAO I don't know where some of you came up with; "there is no such thing as warped rotors." It makes me laugh everytime I see it.

is ur car aligned? my friends 300zx shakes when he brakes and he just needs to get the brakes aligned, but he's too lazy to do it

 

i have never heard of aligning the brakes. Are you sure thats a real thing? Perhaps you talking a normal fron end alignment? ie. adjusting the toe/camber/caster and all that good stuff.
If that were the case he would only pull hard to one side.
Could be anumber of thing.
Is it doing it while the car is driving or only under braking conditions?

 

I know buddy. Thats why it was in quotes.

Its impossible to warp rotors on street cars with street brake setups.

 

Your joking, right?
