Brake pulsation — Saturn, Buick, Chevy, Pontiac

Brake pedal pulsates

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.
