Pulsations,also (ABS)come on when turn hard left,or right.Had it tested by penntson auto,they say sensor keep pulling loose. But the rotors I,replaced all four,and brakes also.
Brake pedal pulsates when brakes applied. Dealer said rotors warped but plenty of material on my ceramic disc brake pads.
Found this recently. About to have this done. GM reports that owners of 2005-07 Relay, Buick Terraza, Chevy Uplander, and Pontiac Montana minivans may experience brake pulsation, even if they’ve had a brake job done recently. The problem has been traced to poorly designed dust shields that allow road debris to get thrown at the rotors. All that grit produces excessive and uneven rotor wear. The new dust shields are #19167950 for the left side, and #19167253 for the right side. Once you install the new shields, have the old rotors machined or replaced so you can start fresh.
When brakes are applied, it vibrates. Still stops tho
Front rotors have had to be replaced 3 times in 200000 miles
Same as described...looking for a fix
Passenger side wheel has pulsations- changed the brakes and rotors now they say its the bearings in the hub on that wheel.
same as some of the rest but more at high speed,when braking shakes very bad,had frontend check and nothing was found,except rotors&brakes.(firstname.lastname@example.org)
When stopping at highway speeds, I get a vigorous shake as the van comes to a stop. Usually the Service ABS System light will illuminate as well.
