BDFHYK Rear Disc Brake Caliper Assembly Pair for Acura RDX / Honda CR-V & Crosstour — 1.5in Single Piston, Direct-Fit

BDFHYK 19B6886/19B6887 rear disc brake caliper assemblies are direct-fit replacements engineered to restore rear braking performance on compatible Acura and Honda models.

These two rear calipers are manufactured to match OE dimensions and mounting points so they install like original equipment on Acura RDX (2013–2018) and selected Honda CR-V and Crosstour years and engines. Each caliper features a single 1.5-inch piston, standard inlet and bleeder thread sizes, and arrives with the hardware and guidance you need to swap them into your vehicle without guesswork.

Will these calipers fit my vehicle?

They are designed specifically for the listed model years and engine configurations. Confirm fitment by matching your vehicle year, model, and engine size to the compatibility list and cross-referencing OE part numbers if available.

• Compatible models: Acura RDX 2013–2018 (3.5L V6)
• Honda CR-V 2007–2016 (2.4L L4)
• Honda Crosstour 2012–2015 (2.4L L4 / 3.5L V6)
• Replaces OE references: 19-B6886, 19-B6887, 43018-SWA-A10, 43018-T0G-A01

How do these calipers compare to the original parts?

These assemblies follow OE-style casting, piston size, and port threading so they align with factory brake lines and mounting hardware. The pistons and port threads use industry-standard dimensions to ensure straightforward connection and bleeding.

• Single piston design, piston OD 1.5 inches for consistent pad contact
• Inlet port: M10 x 1.0; bleeder port: M10 x 1.25
• Supplied with the necessary bolts and installation guide for a like-for-like replacement

What should I expect during installation and maintenance?

Installation follows the same steps as replacing an OEM rear caliper: lift vehicle, remove wheel, detach brake hose and bracket, swap caliper, torque fasteners, and bleed the system. Routine inspection and proper bleeding ensure steady pedal feel and even pad wear after replacement.

• Includes hardware and instructions to shorten installation time
• Bleed brake lines after installation to remove air and restore firm pedal response
• Inspect pads, rotors, and brake hose condition while caliper is accessible

Why choose a pair of calipers instead of one?

Replacing both rear calipers at once helps preserve balanced braking and uniform wear across the axle. Matched assemblies reduce the risk of uneven braking force and make future service intervals predictable.

• Sold as a pair for left and right rear positions
• Ensures consistent friction and synchronized parking brake operation
• Convenient when pads or rotors are near service limits on both sides

Who is this for: Drivers and DIY mechanics who need a reliable, cost-effective replacement for worn or damaged rear calipers on compatible Acura RDX, Honda CR-V, or Crosstour vehicles. These BDFHYK calipers suit garages that prefer OE-style fitment and technicians seeking assemblies that come with the hardware and directions to finish the job efficiently. If you want dependable compatibility with factory mounting and thread standards while avoiding prolonged downtime, these assemblies are a practical choice.
