I recently replaced all 4 shocks on my 00 tacoma. The ones that were on the vehicle when I bought it were shot! So now I have a vibration / bump coming from the brake pedal while braking. Anyone have any ideas on what may cause this. It was not doing this before the shocks were replaced but now that the shocks have been replaced the front and rear of the vehicle seem to sitting higher. The new shocks are HD Bilstiens.
