About This Part
Rear brake disc for the BYD Sealion 06 EV, covering the 2026 model year and the Sealion 06 EV from 2024-2026. Carried as OE 18504858-00 with reference UDEA-3502111S, this cast steel brake rotor mounts to the rear hub to give the pads a true, flat friction face. A worn, scored or warped rear disc causes vibration under braking and lengthens stopping distance, so replace discs as a pair and fit fresh pads at the same time. Bed the new brake rotor in gently to seat the surfaces before hard use.

Frequently Asked Questions: OE 18504858-00
The number on my old disc does not match, what now?
Do not fit it on OE number alone. Look at the side it came off, whether it sat on the left or right, and how the fixings line up, since a disc can look right and still be for the other side of the car. Check these details against the part before you order, and if anything does not match, hold off fitting it until it does.
Does this brake disc need to be fitted by a professional?
Yes, this is brake work and it should be fitted by a professional. Check the model and the model year exactly as shown on your registration document before you order, since this disc is listed for the BYD Sealion 06 EV under OE number 18504858-00. That detail on your document is what confirms this is the correct rear disc for your car. If it does not match, do not fit the part, and look again at the fitment table on this page to find the correct listing for your vehicle instead.
What is this brake disc made of?
It is metal, new, not reconditioned or reground. To be sure it is the right one for your car, do not go by appearance alone. Find the number stamped into the disc you are taking off and compare it against the OE number listed here, 18504858-00. A visual match is not enough on a braking part, and the stamped number is the only way to be certain before you commit to an order.
Where does this disc fit on the car?
This is a rear disc, fitted underbody, so it sits at the back of the car, not the front. If you are unsure which axle needs replacing, do not guess from where the noise seems loudest. Use the fitment table on this page to confirm rear is correct for your BYD Sealion 06 EV before you order, since fitting a disc to the wrong axle means starting the job again.
