EWO GM Dual-Bleeder JB6 Brake Caliper
Heavy-Duty Engineering & Technical Specs
This is a 100% Brand New New Casting Caliper—not a rebuild. Engineered for maximum rigidity and heat dissipation, this Cast Iron Brake Caliper features a clean silver housing and arrives ready to be abused on the rocks or the highway.
Massive 74mm (2-15/16") Clamping Force
The heart of this Single Piston Floating Caliper is a massive 74mm Piston Caliper (2-15/16" Piston). This provides the hydraulic leverage required for 3/4-ton 4WD application performance, delivering consistent, powerful braking even when running 37" tires or heavier.
The Ambidextrous Dual-Bleeder Advantage
Eliminate the frustration of ordering the wrong side. This Ambidextrous Caliper features a unique Dual Bleeder Screw Design. Because it is a Dual Bleeder Caliper, you can install it on either the Left (Driver) or Right (Passenger) side and always have a bleeder screw at the highest point for a perfect gravity or pressure bleed.
Precision Mounting & Universal Fit
Designed with a standard 7.045” Mounting Span, this Slider Caliper is the primary choice for RuffStuff Specialties Brakes, East West Off Road Brake Parts, and builds requiring EWO R2236, R2236-Kit-1, or RuffStuff R2236 specifications.
The Ultimate GM Disc Brake Conversion Caliper
If you are performing a GM 14 Bolt Disc Brake Conversion or a Dana 60 Rear Disc Swap, this is the specific off road brake caliper you need. It is designed to bolt directly to GM-style brackets on the most popular heavy-duty axles in the 4x4 community.
