If you have an Oldsmobile brake caliper on your car or SUV, then you have disc brakes. Likewise, if you have disc brakes on your Delta 88 or Alero, you have an Oldsmobile brake caliper hiding behind each wheel-or at least behind the front wheels. That's because disc brakes and the Oldsmobile brake caliper go hand in hand; you can't have one without the other. The Oldsmobile brake caliper accepts brake fluid under pressure from the master cylinder. You put the fluid under pressure when you step on the brakes, and it's routed through a network of pipes and hoses to the Oldsmobile brake caliper. Once there, that fluid presses on a piston or pistons inside the Oldsmobile brake caliper, which then press on the brake pads. Those pads squeeze the brake rotor and the resulting friction stops your car. That's how it's supposed to work, anyway. Problems with any of the components involved, including the Oldsmobile brake caliper, can alter the outcome. The main problem that occurs with the Oldsmobile brake caliper is leakage, with frozen pistons following close behind. When corrosion eats away at the insides of the Oldsmobile brake caliper, the resulting friction eats away the seals that hold the fluid in place. You can find a leaking Oldsmobile brake caliper easily by looking for dampness on the housing. A frozen Oldsmobile brake caliper will cause the car to stop erratically, usually pulling to the side opposite the frozen Oldsmobile brake caliper. Either condition can be easily and inexpensively rectified, though: A new or remanufactured Oldsmobile brake caliper is just a mouse click away when you order from us, and we'll ship your new parts the same day you order too. After all, brake parts like your Oldsmobile brake caliper are just too important to ignore!
