Q: How to Replace the Front Brake Dust Shields (FE1) on Cadillac CTS?
A: To remove the front disc Brake Dust Shields (FE1), elevate and support the vehicle while removing the tire and the wheel assembly. Support the brake caliper with heavy mechanic's wire or similar whenever it's removed from its mount with the hydraulic flexible brake hose still connected or failure to do so may damage the hose causing a leakage of brake fluid. But off the brake caliper and caliper mounting bracket as an assembly from the suspension knuckle with no tension being on the hydraulic brake flexible hose and do not remove the hose from the caliper. Then, take out the front wheel bearing assembly and the dust shields of the Steering Knuckle. When installing the new dust shields, clean any rusts or contaminants from the wheel bearing flange & brake rotor mating surfaces using the wheel hub resurfacing kit(J 42450-A) in order to reduce excessive lateral runout & brake pulsation. Clean the mating surfaces of Steering Knuckle dust shields, install the dust shields to the Steering Knuckle, followed with the wheel bearing assembly. Finally, reinstall the brake caliper and caliper bracket in an assembly to the suspension knuckle, re-mount the tire and wheel assembly on, and have the vehicle lowered.
