E-Ride Pro - SS 3.0 / SR - OEM Rear Brake Assembly

This is the Type 2 rear brake assembly for the E Ride Pro SS3.0 and SR, the updated DOT4 hydraulic system that replaced the earlier Type 1 rear setup. Unlike the front-side E7766R, this one ships with the caliper already paired to the cylinder pump, so it's a more complete unit right out of the box, plus the two mounting screws needed to bolt it in. On these bikes, the rear brake runs off the left-hand lever, so this is the part behind that circuit rather than a mislabeled front-left component. A rear brake that's gone soft, spongy, or lost bite is usually traced back to the pump or caliper seals rather than the pads alone, and replacing the complete assembly clears both possibilities at once. As with the front Type 2 system, this only pairs with bikes already running DOT4 fluid, DOT4 and mineral-oil systems aren't interchangeable. This is the fix for a rear brake that a pad swap and bleed haven't resolved.
