Rear Brake Caliper With Bracket 18B5047 for Jeep and Dodge - Reliable

Our review of the Rear Brake Caliper With Bracket 18B5047 focuses on fitment and value for owners of select Jeep and Dodge models. This caliper is aimed at DIY mechanics and repair shops who need a direct-replacement rear caliper that bolts up with minimal fuss; the single biggest reason to buy is its broad vehicle fitment across Wrangler, Wrangler JK, Liberty and Nitro models combined with a phenolic piston that reduces heat transfer. The review examines fit, build, and installation based on specifications and customer feedback to help buyers decide if it meets their needs.

Key Features

• Vehicle Fitment: Covers rear left and rear right positions for multiple Jeep Wrangler, Wrangler JK, Liberty and Dodge Nitro years, which simplifies sourcing a replacement caliper.
• Piston Construction: Uses a phenolic piston that helps reduce heat transfer to the brake fluid, lowering the risk of fluid fade under normal driving conditions.
• Ports and Threads: Bleeder and inlet ports use M10 x 1.0 threads, matching OEM fittings for straightforward hose and bleed screw connections.
• Plug-and-Play Installation: Ships as a caliper with bracket so it bolts up to the existing mounting points and often uses existing hardware for a quick swap.
• Quality Control: Built to meet or exceed OEM specifications, offering a durable replacement option for common rear brake failures.

Who It's For

This caliper is a solid match for owners of Jeep Wrangler JK 2018, Wrangler 2007-2017 (3.6L and 3.8L), Jeep Liberty 2008-2012, and Dodge Nitro 2007-2011 who want a cost-effective replacement that fits without modification. It is especially useful for DIYers comfortable with brake work who appreciate a caliper that arrives with the bracket and matches OE port fittings.

Shops replacing rear calipers on these specific models will find the part convenient for common service jobs. Those who need calipers with different piston materials, or who require aftermarket performance upgrades for racing or heavy towing, should look at purpose-built performance calipers instead.

Frequently Asked Questions

Will this caliper bolt directly onto my Wrangler or Nitro?
Yes, the caliper includes the bracket and uses OEM-style mounting and M10 x 1.0 ports so it typically bolts directly onto the listed Wrangler, Liberty and Nitro rear positions.

Does the caliper come with hardware and pads?
The package includes 1 brake caliper with bracket; customers commonly report hardware included, but pads are not specified and may need to be reused or purchased separately.

Is the piston material suitable for heavy towing or track use?
The phenolic piston reduces heat transfer and is fine for street and light towing, but those needing heavy-duty or track-focused performance should consider specialized high-temp metal-piston options.
