Why this unit sells

Buyers searching cast iron brake rotor look for the strengths listed here: direct fit, verified reference and wholesale packing.

Construction & materials

Built to the original equipment drawing, the Brake Disc uses Iron and follows the same inspection checkpoints as the reference sample. Tolerances that affect installation are held to the drawing rather than adjusted on the bench.

• Iron construction for daily and workshop use.
• Surface treated to resist corrosion in road and workshop conditions.
• Dimensional check against the reference sample before packing.

Material and build choices answer the most common brake disc replacement and brake disc guide questions from workshop buyers.

Application & fitment

Suitable for Scania. Brake Disc is stocked for these markets and model families so buyers can match demand without re-checking every listing.

Technical insights

Field note. For a Scania 4-series or PGRT truck, this 430 mm vented disc is where brake energy ends up: the air disc caliper clamps it, the friction faces convert motion into heat, and the internal vanes dump that heat into the airflow. Failure patterns are typical of heavy discs: thickness variation that the driver feels as pedal pulsation and cab vibration, heat crazing after sustained mountain descents, scoring from pads worn to the backing, and rust ridges after long periods of storage. Because the disc also sets the thermal ceiling of the whole brake, a thin or cracked rotor shortens every stop that follows it.

Technical background. Wheel-off work on this reference follows air-disc practice. The disc is a thirty-kilogram-class vented casting mounted with ten bolts on a 237 mm bolt circle with M16 x 1.5 thread; some suppliers mark the disc directional, so respect the rotation arrow when fitting. Clean the hub face and bolt threads, seat the rotor flat, and torque the bolts to the chassis specification in the prescribed sequence, re-checking after the first run. Support the caliper properly, keep wear-sensor wiring clear, and confirm free rotation before the wheel goes on. New pads and a new disc should be bedded with moderate stops rather than a loaded descent.

Field note. Thickness governs the maintenance decision. The disc runs 45 mm new against a 37 mm minimum; measure the friction band at every pad change and log readings per wheel position so wear rates per route become visible. Inspect for heat spots and edge cracks after heavy braking periods, for scoring beyond what new pads can bed into, and for packed debris in the vent channels on construction or off-road duty. Replace in axle pairs when one disc reaches the limit, and never machine below the minimum to extend life. Seasonal checks before winter and after summer heat catch most developing disc problems early.

Field note. The commercial logic of this reference is consolidation. Compare offers against the fixed data set: 430 mm diameter, 45 mm thickness, 37 mm minimum, 131 mm height, ten holes on 237 mm, 208 mm centering, vented, and roughly 29-32 kg depending on brand. Quotes that differ on any of these points describe a different disc. Beyond dimensions, foundry consistency and balancing quality separate the brands more than packaging does.

Field note. Approval evidence for this application family is explicit. The TRW equivalent DF5014S carries test mark E4 90R 02 C0728 / 2692, which is the marking format of an ECE R90 approval for a replacement truck brake disc, and supplier listings for the 1852817 reference state R90 approval as well. On the material side, manufacturers describe HT250 gray cast iron, hardness in the 187-241 HB band, and dynamic balancing referenced to ISO 1940 for smooth rotation at road speed. A buyer who needs documented conformity should read the approval mark on the casting, keep the paperwork with the vehicle file, and treat unmarked discs as unverifiable.

Application context. The buyer base is haulage and construction fleets running Scania 4-series trucks built from 1995 through 2004 and the later PGRT ranges, where one disc covers front and rear positions on models from the P230 up to the R500 in catalog fitment lists. Fleet workshops order in multiples, keep per-axle wear records, and favor suppliers who hold regional stock, because a brake-related downtime day is a lost revenue day. Used-truck exporters and parts traders serving markets where 4-series Scanias still work daily form the second group, buying this reference in mixed Scania consolidation orders alongside pads, sensors and related 430 mm discs.

Deep dive. On Scania 4-series trucks from 1995-2004 this disc is a hub-mounted, air-brake part, so the renewal package is wider than pads. Fit a full axle set of pads rated for the tractor's gross weight, and while the hub is open check bearing play, the hub oil seal and every wheel bolt – hub-piloted ten-stud wheels hide stretched bolts under clean paint. Inspect the air disc caliper's guide pins and bellows for tears that cause taper wear, verify the speed sensor air gap, and renew a rusted dust shield before it feeds grit onto the new friction face.

Application context. A truck disc of this class needs controlled transport: palletized with cardboard interleaves, banded so strap never touches a friction face, and preferably wooden-crated for export consignments. At 25 kilograms or more per unit, two-hand carries are the rule, and shop gloves prevent lacerations on machined edges. Keep the rust-preventive film on the hat and bore until the disc meets the hub. In storage, avoid stacking face-to-face without separators and keep cartons off cold concrete, where condensation cycles cause flash rust. First-in-first-out rotation keeps protective coatings within their effective life.

Deep dive. Truck-bay tooling is the baseline: a lift or axle stands rated for the corner, a trolley jack under the hub, and the manufacturer's tool for retracting the caliper tappets – forcing them wrecks the seals. Use a calibrated torque wrench on caliper brackets and wheel nuts; the hub uses a ten-stud pattern, and impact-only tightening distorts the disc and causes taper wear. A wire-brushed hub face, a dial indicator for mounting runout and brake cleaner for the shipping oil round out the prep. Support the caliper on a stand, never on its air hose.

Technical background. Where these trucks run, seasons write their signature on the disc. Nordic and Baltic winter salt scales the vane edges and rusts the hat, so flush wheel ends after salted routes and expect Monday-morning rust that clears with gentle stops. Hot-season haulage in southern routes is the wearing season: sustained grades with a loaded trailer heat a thinning disc toward heat checking, so record thickness before and after summer. Autumn gritting scours edges on both axles. A 1995-2004 truck is often on regional mixed duty, so set inspection by route class rather than by calendar.

Technical background. Require a per-batch dimensional report covering diameter, thickness, height, hole count and pitch circle, tied to a batch code on each casting, plus a material certificate for the grey iron grade and hardness. Confirm ECE R90 approval documentation for the sold number and the plant's IATF 16949 status. Retain one sample disc per approved batch and receive subsequent pallets against it, weighing random units.

Application context. The 1852817 serves a long production run – the 4-series from 1995 through 2004 – during which Scania revised hub designs, bolt patterns and disc thicknesses, and the near-number family means a single digit separates different heights or hole counts. Because cross-reference tables lump it into multi-brand axle groups, deliveries are occasionally mis-shipped as the visually similar Mercedes-family disc. Verify against the removed casting, not the vehicle badge: measure diameter, thickness, total height, bolt count and pitch circle, and check whether the wheel mounting is hub-piloted. Chassis and axle plates beat model-year guesswork.
