The EBC ED9993 is a rear pad set from EBC's Extra Duty line, sized for the 4.6-liter V8 Lexus GX460. It uses a carbon-granule friction material that the manufacturer calls rotor friendly, low in dust, and quiet in use. Each set includes NUCAP piston insert shims, which damp noise where the pad meets the caliper. Buyers who want firmer cold bite and cleaner wheels than a basic organic pad gives them, without the harsher rotor wear of heavier metallic compounds, will find the trade-off worthwhile. Pair it with a Lexus GX460 rear brake pad upgrade, a GX460 4.6 V8 pad change, or a 2010-2023 GX460 rear braking refresh. Fitment listings disagree on the exact year range and trims, so confirm your VIN and trim before ordering.
Start with the bedding process. The manufacturer says pads should first seat through normal urban driving over roughly 600 to 800 miles, then complete the surface cure with 15 medium-to-heavy brake applications. A red brake-in coating on the pad face is meant to give safe braking from the first stop. Owners on user forums say the rear caliper on this platform is more involved than the front. You need to remove the bolts on the back of the caliper so it can slide up before the pads will come out, so plan for extra time and check the caliper hardware before you start.
Fitment information is not consistent across sources. Listings show different year ranges and trims, including Base, Luxury, and Premium. Check your VIN against the manufacturer's fitment data before you order.

Rear pad replacement on the GX460 is a manageable job for a home mechanic, but it is more involved than the front. Owners on user forums say the rear caliper must be partly disassembled, with the bolts on its back side removed so the caliper can be slid up to free the old pads. Work on one side at a time so you can use the untouched side as a reference. Before you install the new pads, check the caliper slide pins and hardware, and make sure the shims sit correctly. Follow the bedding procedure above after installation to get the best from the new pads.
