I have a 1994 Civic EX Sedan with a B20b swap. I recently got new tires mounted and balanced and just got an alignment today thinking it may have been part of the problem.

<u>The Problem: My car shakes very violently when braking anywhere over 45 mph. It doesn't pull at all to the sides. </U>
I have gotten it aligned and I had my mechanic recheck to make sure everything was balanced and I got a printout with my alignment from today and everything was perfect when they were done.

I am thinking warped rotors but it only does it anywhere over 45.

Thanks for any help. Sorry my post was kinda long.

 

Mine does the same, but not as bad. Just from 37 to 47 mph. It's warped brake rotors. I'm going with Brembo flat rotors FTW

 

It could be warped rotors or unevenly worn pads.

Or a torn bushing in your endlink/lca.

It's more likely pads or rotors though.

 

I still put my $$ on warped rotors, or maybe uneven pad wear as ekFG said

I'm going to put on PBR/Axxis pads on my car

 

most likely your rotors bro, if your pads are out or close to being so i would throw on some hawk pads.

 

Ok I already ordered Powerslot rotors all the way around with the hawk pads. Thanks. I jsut wanted to make sure I did the right thing.

 

Yep. You installing them?

 

It may not be warped rotors. If you feel the shimmy mostly in the steering wheel and do not feel much if any pulses in the pedal, it is likely runout. Runout can be caused by a bad hub, or a bad rotor. You usually feel warped rotors in the pedal.

Like someone else mentioned, a bad tie-rod end or inner tie-rod could cause this as well. Or a bad lower ball joint, upper ball joint, or other front suspenion bushing.

 

It is everything the entire car shakes and the pedal moves. It has gotten so bad that my door panel inserts look like they are wiggling off the doors when I brake.

 

You may have a combination of warped rotors and excessive runout.
