civic shakes
 

hi there
am new here! i ve just recently bought a 99 civic vti 5 door hatch. my
problem has just started recently, i noticed it when i was drivig about
130 mph, when braking the rear of the car shakes like an eathquake,
continues to do so until i get to about 70 mph, i was approaching a
bend when i braked. i have been told that it maybe my wheel bearings or
discs might have warped. how can you tell which one it is? also when
driving about 5mph the rear brakes have a squeak on them, which is
really annoying at times, but you cant hear it as soon as i spped up.
could you guys tell me what my probs could be from experience and could
the both problems be linked.
open to all suggestions!!
thanks!
