How to Remove the Front Caliper of an Oldsmobile Aurora

The brake calipers on the Oldsmobile Aurora press the brake pads against the spinning disc, or rotor, to slow or stop the vehicle. Over time, those calipers can wear or sustain damage, leading to uneven or poor braking. To avoid potential braking problems, inspect, and replace if necessary, the calipers when changing the brake pads.

Instructions

1

Remove two-thirds of the brake fluid from the master cylinder using a turkey baster or siphon pump. The master cylinder is located on the driver's side rear of the engine compartment and has a large plastic reservoir atop it.

2

Loosen, but do not remove, the lug nuts on the front wheels with a tire iron. Lift the front of the Aurora with the jack and support it with jack stands. Remove the lug nuts completely and take off the wheels.

3

Thread two of the lug nuts on the wheel studs loosely to keep the rotor on the hub once the caliper has been removed.

4

Use the socket and ratchet to remove the bolts that hold the brake line to the caliper. Remove the brake line from the caliper, which fits over the rotor like a clamp. Plug the hose with the shop rag to avoid fluid loss.

5

Place the C-clamp over the caliper with one end on the face of the piston. Compress the caliper piston into the bore by turning the handle on the C-clamp inward. Place a thin piece of cardboard over the face of the piston to prevent surface damage.

6

Remove the caliper mounting bolts with a ratchet and socket. Remove the caliper from the mounting bracket.
