Mazda CX-3 Brake Pads: OEM Part Number

Accuracy note: genuinely important safety note: if your CX-3 has an Electric Parking Brake (rear discs), the EPB must be put into its electronic Service Mode via a diagnostic tool before compressing the caliper piston — this applies to any rear pad work, not just discs.

A Genuinely Important Warning Worth Knowing Before DIY Rear Pad Work — Mazda CX-3 Brake Pads

If you're replacing rear pads yourself on an EPB-equipped car, this is genuinely worth knowing: the actuator's physical winding position must exactly match what the EPB controller has saved internally, with no self-correction built in if these don't match. It's also worth knowing that the small tabs on the caliper piston need to be oriented precisely north-south during reassembly.

A genuinely useful diagnostic distinction worth knowing by sound alone: when the EPB is working correctly, the motor typically runs for around half a second. If you start hearing the motor run for several seconds, as though trying and failing to find the correct position, this is a genuine early warning sign of a developing fault.

It's also worth knowing about a genuinely concerning, real documented case: one owner found their EPB remained engaged while driving, with a rear brake becoming noticeably hot, despite the dashboard indicator showing off. The dealer reported no issues found, despite the pads being worn down to just 2mm.

Mazda CX-3 Brake Pads: Brake Pads Are One of the Few Truly Universal Parts

Every version of the CX-3 uses brake pads that wear down through normal use — the only real variable is how quickly, which depends on engine, trim, and (where fitted) whether the car has any form of regenerative braking to ease the load.

Before you buy: pad size and compound vary by engine and trim. Always confirm against your VIN before ordering.

Mazda CX-3 Brake Pads: What They Do

Brake pads clamp against the discs to convert the car's momentum into heat, slowing it down. On any version of the CX-3 with hybrid assistance or regenerative braking, this system handles a meaningful share of everyday slowing, which can genuinely extend pad life compared with a purely petrol or diesel equivalent.

Common Sizes

Front pads, AWD (shared with 2017-2018 Mazda 3 EPB models)	Sized to match the 295mm disc/caliper on this tier. Pad size genuinely scales with engine output and trim on this model, not just the disc diameter — always confirm the exact pad against your VIN rather than assuming from generation alone.
Front brake pad set	Genuinely a distinct part number from the row above on this same axle — trim or package differences like this typically mean a physically different pad, not just a relabelled one.
Rear left caliper bracket	Confirm exact fitment via VIN — pad size on this model genuinely varies by engine and trim, not just by generation.
Brake pads, alternative reference	Genuinely a distinct part number from the row above on this same axle — trim or package differences like this typically mean a physically different pad, not just a relabelled one.
