About This Part
Left rear brake caliper (OE 18504884-00 / UGEA-3502003) built for the BYD Song Ultra EV (2026), the 2026 Sealion 06 EV and the Sealion 06 EV (2024-2026). The integrated electric parking brake motor works the rear pads for normal stops and holds the car when parked, so this caliper assembly does the job of a separate handbrake mechanism. It comes as the caliper body plus its guide and mounting bolts. Fit it on the driver-side rotor, bleed the hydraulics, then calibrate the EPB. The right-hand partner is OE 18504883-00.

Frequently Asked Questions: OE 18504884-00
How do I know this caliper is for the left rear and not the right?
This listing is for the left rear position only, matched to OE number 18504884-00. Before you order, look at the caliper currently fitted to the car and check its OE number against this one. If the numbers match, you have the right side. Fitting a caliper to the wrong side can mean the bleed nipple and hose connection end up facing the wrong way, so the check is worth doing before you commit to buying rather than after the box has been opened.
The number on my old caliper does not match 18504884-00, what do I do?
If the number stamped on your old caliper does not match 18504884-00, do not assume this is the wrong part, since the same caliper is sometimes listed under other references, including UGEA-3502003 for this one. Guessing from the number alone can lead to the wrong order either way. Use the quote route on this page, give the details from your old part, and let that check confirm whether this caliper is the right one for your car before you buy.
Can I fit this myself or should a garage do it?
A rear caliper carries the vehicle's braking force, so this is not a job to guess at if you have not bled and torqued a brake system before. It sits at the underbody and connects into the hydraulic circuit, so a fitter with the right tools and a proper bleed procedure is the safer route. Once fitted, check the model and model year shown on your registration document match what you ordered against, then have the brakes tested before the car goes back on the road.
What is this brake caliper made of?
Metal is what this caliper is made of, not a mix of materials that could vary between listings. Being metal, it is not something you can judge by appearance or weight alone to check it is correct for your car, so the number does the real work. Find the number stamped on the part you are taking off and compare it with 18504884-00, or with the alternative reference UGEA-3502003, since either match confirms this metal caliper is the same one fitted to your car.
