PowerStop Disc Brake Caliper P/N:L2683A
PowerStop L4639 front right brake caliper for the 1997-2005 Chevrolet Venture and other vehicles clamps the brake pads against the rotor to slow the wheel. It belongs to the Autospecialty line of PowerStop brake calipers.
A disc brake caliper that sticks or leaks can show up as the vehicle pulling to one side, pads wearing unevenly or brake fluid around the caliper. Those signs can point to this part, but a collapsed brake hose or worn pads can be behind them too, so find the cause before replacing it.
It is listed for a wide range of Buick, Chevrolet, Oldsmobile and Pontiac models, among them the 1997-2005 Chevrolet Venture, the 1997-2005 Buick Century and the 2000-2005 Buick LeSabre, each taking one caliper on the front right. This listing is one caliper; the front left is a separate part, and both sides are normally replaced together.
