OEM Part Number: confirm via VIN — front discs (aftermarket) Brembo 09.D417.11 / Bosch 0 986 479 F49

Accuracy note: Covers the Toyota C-HR (2016-) as listed in the UK aftermarket catalogues. Front brake discs are sold by diameter and thickness, and most models have two or three disc sizes depending on engine, brake size and trim — a 278 mm disc will not fit a car built with 300 mm brakes, so the caliper carrier and the disc must match. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with diameter x thickness in mm; genuine numbers are shown only where a listing quotes one. Measure the old disc or check the brake size against your VIN before ordering, replace discs in pairs with new pads, and scrap any disc at or below its minimum thickness.

Front brake discs (aftermarket)	Brembo 09.D417.11 (299 x 28 mm, vented, 5 holes, coated, min 25 mm); Bosch 0 986 479 F49 (299 x 28 mm, vented, 5 holes, coated, high-carbon, min 25 mm, ECE-R90); ATE 24.0128-0317.1 (299 x 28 mm, vented, 5 holes, coated, min 25 mm); Zimmermann 590.2828.52 (298 x 28 mm, vented, drilled, 5 holes, coated, min 25 mm, ECE R90); Blue Print ADT343316 (299 x 28 mm, vented, 5 holes, coated, min 25 mm); JP Group 4863105700 (299 x 28 mm, vented, 5 holes, coated); JP Group 4863105600 (305 x 28 mm, vented, 5 holes, coated, min 25 mm).
Disc sizes & variants	298-299 x 28 mm vented is the standard front disc. A single 305 x 28 mm reference (JP Group 4863105600) is also listed, with no note of which version takes it.

A Genuinely Useful Myth Worth Correcting: Discs Don't Actually "Warp" — Toyota C-HR Brake Discs

If you're feeling a pulsing sensation through the brake pedal and have been told the discs have "warped," this is genuinely worth understanding: discs don't actually physically warp or bend. What's really happening is that pad material transfers unevenly onto the disc surface, creating slightly higher and lower points around the circumference — this is what you feel as pulsing. A common cause worth knowing: holding the brake pedal down while stationary immediately after hard braking, rather than releasing it once stopped, keeps heat concentrated in one spot and encourages exactly this kind of uneven deposit.

A genuinely counterintuitive fact worth knowing if your car is a hybrid: regenerative braking typically means the rear brakes see considerably less use than you'd expect, since the electric motor handles much of the everyday deceleration. This can mean rear discs corrode more than the fronts — the opposite pattern to what most owners expect based on conventional cars.

It's also worth knowing that a car left standing overnight with heavily corroded discs can occasionally feel genuinely stuck when trying to pull away — a firm, deliberate application of the accelerator followed by a couple of firm brake applications once moving typically clears this within a few hundred metres.

Toyota C-HR Brake Discs: The Part That Pads Depend On

On the Toyota C-HR, it's a paired system: let either one wear too far and the other suffers for it, which is why so many "just a pad change" jobs end up including discs once a mechanic actually looks.

Before you buy: disc size and design vary by trim, engine size and whether your car has the standard or "sport" brake package. Always confirm against your VIN before ordering.

Toyota C-HR Brake Discs: What They Do

Brake discs provide the surface the brake pads clamp against to slow the car, converting momentum into heat through friction. Larger, sportier trims of the C-HR typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.
