OEM Part Number: confirm via VIN — front pads (aftermarket) Brembo P 61 103 / Bosch 0 986 494 623

Accuracy note: Covers the Citroen C4 Cactus (2014-2020) as listed in the UK aftermarket catalogues. Front brake pads are sold by caliper system (ATE / Teves, TRW / Lucas, Bosch, Akebono, Brembo etc.) and by pad size, and one model usually has two or three pad sizes depending on engine, brake size and trim — a wrong size will not fit the caliper. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with their width x height x thickness in mm; genuine numbers are shown only where a listing quotes one. Measure the old pad or check the caliper system against your VIN before ordering, and fit a new wear sensor where the set is only 'prepared for' one.

Front brake pads (aftermarket)	Brembo P 61 103 (137 x 59 x 18 mm, no wear contact included, Bosch system); Brembo P 61 066 (137 x 52 x 19 mm, no wear contact included, Bosch system); ATE 13.0460-3994.2 (136.8 x 52.0 x 19 mm, not prepared for a wear indicator, Bosch system); Bosch 0 986 494 623 (137 x 51.5 x 18.8 mm, Bosch system); Valeo 301464 (137 x 49 x 19 mm, no integrated sensor, Bosch system); Ridex 402B0049 (137 x 52 x 19 mm, no wear contact included, Bosch system); Ridex 402B0810 (133 x 60.2/52.5 x 18.8 mm, no integrated sensor)
Pad sizes & variants	The usual front size is 137 x 49-52 x 18-19 mm; a taller 137 x 59 x 18 mm pad (Brembo P 61 103) and a 133 mm wide Ridex pad are also listed.
Genuine (OE) numbers quoted	None quoted in catalogue listings — order genuine pads against your VIN
Fitment notes	All the labelled front sets are for the Bosch brake system and none includes a wear contact; no engine-specific fitment is given.

A Genuinely Important Warning: Never Leave the Ignition On While Changing Rear Pads — Citroen C4 Cactus Brake Pads

If your car has an electronic parking brake, this is worth taking seriously before starting a rear pad job: leaving the ignition switched on while releasing the handbrake and changing the pads has been documented to cause a genuine EPB fault, with real confirmed fault codes (C156C-92 and C1561-00, relating to the actuator sensors) appearing afterward. Always switch the ignition fully off once the parking brake is released and before starting any work on the rear calipers, rather than leaving it on for convenience.

A genuinely important distinction depending on your car's age: earlier EPB-equipped models (broadly pre-2013/14) use a single central motor under the front seat connected to a Bowden cable running to both rear wheels — on these, pads can genuinely be changed without any diagnostic computer at all, since the cable simply releases when the parking brake itself is off. Later models switched to individual motors built into each rear caliper, which do require diagnostic equipment (Lexia or DiagBox) to put into service mode before pad replacement. Confirming which system your specific car has before starting the job will save you a wasted trip either buying unnecessary diagnostic access or discovering partway through that you do need it.

If the EPB has stopped engaging or releasing after pad work, a genuinely useful first troubleshooting step before assuming a deeper fault: turn the ignition on and leave it for around 5 seconds, then activate the parking brake switch to apply it and hold for a further 5 seconds. If this doesn't restore normal function, the fault is likely to need proper diagnostic equipment to investigate further.

Citroen C4 Cactus Brake Pads: Brake Pads Are One of the Few Truly Universal Parts

Every version of the C4 Cactus 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.

Citroen C4 Cactus 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 C4 Cactus 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

1.2/1.6 variants, front pad	Sized to match the 266mm 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.
1.2 THP 110 and higher-power variants, front pad	Genuinely a different, larger pad to match the 283mm disc/caliper on this higher tier — not interchangeable with the standard-tier pad on the same axle.
Rear pads (drum-braked on some lower trims)	Sized to match the 249mm 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.
