Wagner Brake ZD921 front brake pad for the 2005-2008 Cadillac STS and other vehicles is a ceramic pad that presses against the rotor to slow the car, and it comes with a mechanical wear sensor.
- Wagner QuickStop line, designed and tested to restore like-new performance
- 100% post-cure process for even friction performance through the life of the pad
- Application-specific design to reduce noise-causing vibration
- Application-specific materials, formulated for the needs of each vehicle
- Wagner OE25 zero-copper friction formulation
A squeal from the wear sensor, a grinding noise or a pulsing pedal can mean the pads are worn. Before you replace them, rule out a sticking caliper or a rotor problem, since either one can also make the car pull or the pedal pulse.
This front brake pad is a direct-fit replacement for the 2005-2008 Cadillac STS, the 2005-2008 Pontiac Grand Prix and the 2003-2007 Cadillac CTS. The 2003-2007 Cadillac CTS takes one set.
