The EBC Ultimax2 UD1304 is a rear disc brake pad set for the 5.7L V8 Lexus LX570. The manufacturer says Ultimax2 pads are made at its friction plant in Bristol, UK, and use a fully non-metallic compound with no steel fibre, which makes them gentler on cast iron rotors. EBC rates the friction material GG and gives it a Code N environmental rating under the US system, and the pads carry ECE R90 approval for public road use.
Compared with stock or budget rear pads, the case for this set is durability, low rotor wear, and a quiet, progressive feel for daily driving. EBC says its Brake-In top coating speeds up bed-in, so the pads reach full contact sooner after installation. The manufacturer also positions the range as an OE-equivalent option at a lower price than original parts. Be realistic about the use case: the manufacturer states these pads are not suitable for track use. Owners on user forums report noticeable brake dust with this compound, so plan on more frequent wheel cleaning. Shoppers searching for LX570 rear brake pads, low-dust non-metallic 5.7 V8 pads, or EPB service mode pad changes will find this set matches a street-focused, quiet-stopping use case.
Owners on user forums report that the LX570 rear calipers use an electronic parking brake, and the pistons need to be retracted through the vehicle's service mode, usually with a scan tool, rather than by forcing them. Some owners say the mode did not behave as expected, so confirm the procedure before starting.
Owners on user forums have reported heavy brake dust after fitting this EBC compound on a different Lexus model, a 2018 ES350, while also noting stronger initial bite than the factory pads. Results on the LX570 may vary.
No. The manufacturer states that Ultimax2 pads are not suitable for track use and are designed for road driving in hot and cold conditions.
Rear pad replacement on the LX570 is a moderate DIY job for an experienced home mechanic. The main hurdle is the electronic parking brake. Put the EPB into service mode with a compatible scan tool before you press the pistons back, since owners on user forums report that forcing a piston against the electric actuator risks damage. Park on level ground with the wheels chocked, and work on one side at a time so you can use the other caliper as a reference. Have a torque wrench, brake cleaner, and a caliper lubricant on hand, and check caliper slide pins and boots while the caliper is off. Confirm all torque values in the factory service information rather than relying on memory. After installation, the manufacturer recommends a bed-in procedure to get the Brake-In coating working properly, so make a series of moderate stops before any hard braking. Finish by cycling the parking brake and confirming there are no EPB warnings on the dash.
