PowerStop L4921 rear left brake caliper for the 2005-2007 Ford F-250 Super Duty and other vehicles clamps the pads against the rotor to slow the wheel.
Dragging at the rear left wheel, the vehicle pulling to one side or brake fluid around the caliper can mean this disc brake caliper is worn, though a rear brake hose or the rear pads can also be behind them, so find the cause first. Replace calipers in pairs; this listing is one rear left caliper, and the rear right is a separate part.
This rear left brake caliper bolts on in place of the original stock caliper, with no modifications needed, on the 2005-2007 Ford F-250 Super Duty and the 2005-2007 Ford F-350 Super Duty.
