Frequently Asked Questions: OE 17593816-00
Will this brake disc fit my BYD Sealion 05 EV?
This disc is matched to the BYD Sealion 05 EV only, under OE number 17593816-00, with no other model shown alongside it. If your car looks close but the name is not identical, do not assume the fit carries across, since a similar badge does not mean the same disc. Check the model and the model year exactly as printed on your registration document before you order, so what arrives matches the car in the drive rather than the one it resembles.
The number on my old disc does not match, what should I do?
If the number stamped on the disc you are removing does not read 17593816-00, do not fit this replacement, because that number is how a rear brake disc is confirmed rather than by look. Discs can appear alike while being built for different cars, so a mismatch on the number is worth more than what fits by eye. Find the OE number stamped on the part currently on the car, note it exactly, and compare it against 17593816-00 or against the listing shown as UNEC-3502011S before you go ahead.
Do I need a garage to fit this rear brake disc?
This is a new metal rear disc, supplied as a single unit rather than a kit, so whoever fits it should already be comfortable working on a braking system, since getting this wrong affects how the car stops. If you are unsure whether the job is within your usual toolkit, look at the photographs on this page first, so you can see exactly what you would be handling before you commit to fitting it yourself. When in doubt, hand the job to someone used to brake work.
What is the rear brake disc made of?
This disc is metal, new, made in China to fit the BYD Sealion 05 EV. Metal discs need to match the exact rear fitment for this model, since a disc that is slightly wrong in diameter or bolt pattern will not seat properly against the caliper. Check the OE number on your old disc, 17593816-00, or the alternative reference UNEC-3502011S, against what is fitted to your car. If you are not certain which one you need, use the quote route on this page and someone will confirm it before you order.
Where does this rear disc fit on the Sealion 05 EV?
This is a rear brake disc, fitted at the rear of the car in the braking system. It replaces the disc behind the underbody area at that axle. The fitment table on this page lists the exact rear disc for your car, so check the OE number on your old disc against it before ordering, or send a photograph of the old disc and its label through the quote route on this page. Keep the old disc to hand and match it against what the table shows, since that confirms you are looking at the correct rear position for your Sealion 05 EV.
