Brake caliper carrier

A brake caliper carrier is the bracket that holds the brake caliper in place over the disc and gives the pads their seat. It bolts to the knuckle behind the wheel, the caliper slides along its two guide pins, and the pads push against its machined ledges every time you brake.Sellers file these under brake carriers, caliper brackets, or brake caliper holders, and on some cars the rear one is sold as part of the caliper itself. So when someone asks what the thing that holds the brake caliper is called, this is it.The carrier is solid cast iron and almost never breaks. What goes wrong is its surfaces: the ledges the pads slide on scale up with rust, the guide pin bores lose their grease and seize, and a thread strips when a bolt is done up dry. The signs it is finished:

• Uneven pad wear: one pad down to metal while its partner is barely used, the surest carrier sign.
• Grinding or rattling from one wheel: a pad rocking on rusty ledges instead of sitting flat.
• A wheel that runs hot: rust scale holding a pad against the disc, and you can smell it after a drive.
• Pulling to one side when braking: one corner gripping later or harder than its opposite number.
• Squeal that new pads did not cure: the pads are vibrating on scale, not touching a wear indicator.
• Pads worn at an angle: a seized guide pin, so the caliper no longer sits square on the disc.

The two most common brake caliper problems are sticking and leaking. A caliper sticks when its piston corrodes or when the guide pins seize in the carrier, so a pad stays pressed against the disc, and it leaks when fluid gets past the piston seal. Sticking is far more often the carrier's fault than the caliper's own.That last point is worth money, because garages sell plenty of calipers for what was a rusty carrier.Parthunt24 collects used brake caliper carrier listings from major used parts marketplaces like Ovoko, ProxyParts, eBay, TotalParts, Opisto, Ecooparts, Ricambipro, and Autoparts24 onto one page, where the caliper carrier price, the axle, and the side of all 44 offers line up for comparison.

Carriers look interchangeable and rarely are.The carrier decides where the pads sit, so it has to match the brake disc diameter exactly: one model often carries two disc sizes depending on engine, and the carrier for the smaller disc leaves the pads hanging over the edge of the bigger one.Pin down the OEM number before anything else, then work through the build. Front and rear carriers are different castings, some cars use left and right versions, and a rear brake caliper bracket can differ again where the handbrake works through the caliper. The same model can also leave the factory with brake systems from two different makers, and their carriers do not mix, so the carrier has to suit the caliper that will slide on it, bolt spacing included.Type the car into the filter panel down the left, and carriers for other cars drop away.

• Vehicle make, model, and year: Brakes get revised at facelifts even when the body looks unchanged.
• OEM part number: Two carriers a few millimetres apart look identical, and the number separates them.
• Front or rear axle: Front and rear carriers are different castings and never swap.
• Left or right side: Plenty of carriers fit either side, but some cars insist on left and right parts.
• Brake disc diameter: The carrier has to put the pads on the disc face, so diameter must match.
• Brake system manufacturer: ATE, TRW, Brembo, and Bosch systems each use their own carriers.
• Engine version: Stronger engines often bring bigger discs, and bigger discs need a bigger carrier.
• Mounting points and bolt spacing: The holes must line up with the knuckle on one side and the caliper on the other.
• Brake caliper compatibility: The caliper has to slide on this exact carrier design, pins and all.
• Condition of sliding surfaces and threads: Scaled ledges, seized pin bores, or pulled threads defeat the point of the swap.

Once the original listing is open, remember what this part really is: three machined surfaces on a lump of iron.Surface rust on the casting means nothing, because every used carrier wears some. What counts is the ledges the pads ride on, the bores the pins slide in, and the threads, and the photos need to show all three.Go through the listing point by point:

• Photos: both pad ledges, both pin bores, and the threads, not just the casting from the side.
• Seller reputation: a dismantler trading for years, with solid recent ratings.
• Compatibility: OEM number, axle, and side, read against your car's build.
• Included components: guide pins, rubber boots, and pad shims in, or the bare bracket?
• Condition: scaled ledges, rounded bolt heads, a pin stuck in its bore, a stripped thread.
• Testing: word that the pins were pulled out and slid freely in their bores.
• Warranty and returns: get them in writing, since a seized bore may only show up on fitting.
• Shipping: heavy for its size, so the postage line deserves a glance before the price does.
• Documentation: which car it left and how many miles that car had covered.

When all three surfaces pass, order the caliper carrier online from that seller on their marketplace of choice.

The caliper carrier price mostly follows disc size and how much comes bolted to the bracket.A bare used carrier for a mass-market hatchback costs about €10-€35, carriers for bigger discs and premium models €35-€80, and a carrier sold with its caliper as one unit €40-€120.On Parthunt24 the lowest caliper carrier price is 7.00. What moves one caliper carrier price above another:

• Disc size: a carrier for larger discs is more iron and turns up less often.
• What is included: pins, boots, and shims in the box spare you another order.
• Axle and side: front carriers are everywhere, some rear ones are hard to find.
• Brand: a maker's stamp and a readable number beat a blank casting.
• Model rarity: common cars mean cheap carriers, low-volume cars the opposite.
• Condition: clean bores and flat ledges earn the higher price.

For scale, replacing a complete caliper costs €150-€350 fitted, which is why saving one by sorting out its carrier is worth the trouble. Sort by caliper carrier price, compare offers across the page, and the best price that matches your discs sits first in the list.

The carrier never works alone: the pads seat on it, the caliper slides across it, and the disc spins between them. A brake caliper carrier replacement usually happens in the middle of a pad change anyway, so look at the rest on Parthunt24 before the wheel goes back on:

• Brake caliper: the part that slides on the carrier, and what people replace when the carrier was the fault.
• Brake discs: the carrier is sized to their diameter, so measure their wear at the same time.
• Brake pads: seat on the carrier's ledges, and go in new whenever those ledges are cleaned up.
• Brake drum: the rear setup on smaller cars, with no carrier but the same rust troubles.
• Brake disc dust cover plates: the thin shield behind the disc, often rusted through by the time the carrier needs work.
• Brake hose: flexes beside the caliper with every turn of the wheel, and cracks with age.
• Wheel hub spindle knuckle: what the carrier bolts to, and its threads matter as much as the carrier's own.
• ABS sensor: sits by the disc reading its ring, and is easiest to inspect with the wheel off.

Clean the carrier's pad ledges and re-grease the guide pins at every pad change, because that ten-minute job is what stops the next set of pads wearing crooked.

Parthunt24 was built on one idea: that whoever is buying a used part should see the whole market before choosing, not just the first site a search engine happened to serve up.That matters most exactly when this part fails, because a bad carrier is usually found mid-job, car up on stands, wheel off, daylight going. Nobody wants to spend that hour opening one breaker site after the next and typing the registration into each, and here nobody has to: every axle, side, and caliper carrier price from Europe's dismantlers sits on a single page, ready to compare. Set your car, sort the offers, take the best deal among them, and find a brake caliper carrier for your car today, while the wheel is still off.
