Frequently Asked Questions: OE 12740246-00
Is this the right hand rear hose?
Yes, this listing covers the right hand rear brake hose assembly, and the left hand rear carries a separate OE number. Sides are named from the driver's seat facing forward, so this is the off side on a right hand drive car and the near side on a left hand drive one. Working from behind the vehicle flips that view, so check twice before ordering. The surest test is the reference on the assembly you are taking off. Match it to 12740246-00 and you know you have the correct corner.
Will this fit my particular car?
This part fits a broad spread of vehicles, so go by the fitment table on this page rather than by the badge on the boot. Match your car on variant and build year, and where you can, read the reference off the hose assembly currently fitted at the right hand rear. If your car is not shown in the table, or you cannot get that reference clearly, send a photograph of the old part and its label through the quote route on this page and we will check it against the OE number before you order anything.
The code on my old hose is SC2E-3561040A. Have I found the right page?
You have. SC2E-3561040A is the alternative reference for OE 12740246-00, so the two identify the same rear hose assembly. Suppliers and the fitted part often carry the SC2E form rather than the OE form, which is why the numbers look as though they disagree at first. If what you can read is neither of these, do not order on the strength of a similar looking code. Send a photograph of the old part and its label through the quote route and we will check it against the fitment table.
Is this something a home mechanic should take on?
We would say no. This hose assembly is flagged as safety critical, since it carries brake fluid under pressure to the rear of the car. Changing it opens the hydraulic system, and the brakes then have to be bled and road tested by someone competent to judge the result. What we supply ends at the box, with no fitting procedure inside it. Give the OE number 12740246-00 to the garage doing the work so they can confirm the fitment against your car before anything is dismantled.
How long does delivery take on this one?
Delivery takes 8 to 25 days from your order to your door. The page shows which state the item is in when you place the order. If the vehicle is off the road, tell us through the enquiry route on this page and we will confirm the position on the day rather than leaving you to work from the wider window. The shipping cost for your country is shown on this page and confirmed at checkout before you pay.
What is the hose itself made from?
The material is rubber, so the flexible portion is a rubber hose with fittings at each end, supplied as one new assembly. Before it goes near the car, lay it beside the part you removed and compare the run and the fittings, then check the fitment table on this page. Leave the protective caps on the ends until the fitter is ready for it.
Why does this page show only one price tier?
Because only the Original/Genuine BYD part has been sourced against OE 12740246-00. No Aftermarket price is offered, so the page shows the single figure you can see. Nothing is being held back, and if an approved alternative is added to the catalogue a second tier appears on this listing without us touching the page. On an assembly flagged safety critical, we are comfortable offering the genuine part on its own. Send the OE number through the enquiry route if you want us to search further.
