GM Dual Bleeder Loaded Brake Caliper

GM Dual Bleeder Loaded JB6 Brake Caliper

A reliable, dual-bleed caliper for disc brake conversions using the GM JB6 platform.

This is the same caliper used in our rear disc brake conversion kits — a GM JB6-style front caliper originally used on 3/4-ton 4WD trucks and vans. It has a 7.045" mounting span and a 74mm (approx. 2-15/16") piston. This JB6 caliper design is the go-to standard for disc conversions using GM-style brackets, making it a great replacement if you're on the trail or away from home and need something that just works.

Thanks to its dual bleeder design, you can install it on either side with no need to keep track of left vs. right. It’s a new caliper (no core charge), pre-loaded with semi-metallic pads, and comes with M10-1.5 banjo bolts. All around, a solid upgrade or replacement for GM-based disc brake conversions.
