Description

Restore firm, dependable braking with the PowerStop Autospecialty Disc Brake Caliper L4858, a rear right direct-replacement caliper that bolts on in place of the original stock unit with no modifications necessary. It drops in as a direct-fit replacement for the 2004-2011 Ford F-150 and the 2006-2008 Lincoln Mark LT — see the Buyer's Guide tab for engine-specific applications. Sold individually, it's built for both DIY and professional installers who want a hassle-free, value-minded caliper swap.

Expertly assembled: new seals, caliper guide pins/bolts, dust boots, bleeder screws, stainless-steel brake pad attachment hardware, and mounting brackets.
High-temperature EPDM rubber dust boots with premium assembly lubricant, designed for smooth caliper operation and durability in harsh conditions.
100% pressure tested and inspected to help deliver reliable, high-quality brake performance.
Bolt-on ready: installs directly in place of the factory caliper — no modifications required.

The brake caliper clamps the pads against the rotor to convert hydraulic pressure into stopping force. Signs the original may need replacing include a caliper that sticks or drags, uneven pad wear, fluid leaks at the piston or bleeder, or a soft brake pedal. If a failed caliper is the cause, this Autospecialty unit replaces it.

How do I know if my brake caliper is failing?
