I tapped into that fuse box in the passenger footwell from the headlamp levelling fuse. Seems to have been fine so far.

Had the same, one caliper seized. To be fair the £270 they quoted for a replacement caliper fitted seemed pretty fair for a main dealer. However I fixed it with some brute force. A bit of heat on the bottom of the caliper and then a lot of decent hits with a drive punch (Link below) and hammer just above the slide pin got it freed. https://smile.amazon.co.uk/dp/B000LFVNNM/ref=cm_sw_em_r_mt_dp_U_.5O4CbCWAF4YD Water had got in and corroded it quite a bit. I didn't have new ones to hand, so cleaned up the hole and pin and gave it a good greasing and it's free now. I'll replace the pin and rubber at some point this year though. This is the grease set I've bought for the using on the Lex https://smile.amazon.co.uk/dp/B07886FP12/ref=cm_sw_em_r_mt_dp_U_l9O4CbB4BPJBT

This any use? https://lexus-europe.epc-data.com/is250_220d/gse20r/2912/engine/1903/27020/ It would suggest it's different from the part number

ECP always seem to have a sale on so don't take their listed price as read. Always worth adding it to the basket and entering the discount code. The brake prices are usually pretty good. If you don't need to collect and can wait for delivery carparts4less are the same company but different branding and can be cheaper than ECP (again they have discount codes too). Having said that I needed something today, so ordered a set of Pagid discs and pads for the front of my IS250 for £83. Been using Pagid for years and always been happy with them.
