Product Overview
815080-1387439-brake-disc is manufactured by SAITE Friction for brake rotor replacement in commercial vehicle fleets. Nominal size Ø432 mm x 45 mm (internally vented), total height 130 mm, weight ≈35.8 kg, matched to the original drawing envelope. Applications cover DAF, which is why fleets standardise on one part number across mixed-brand trailers and tractors. Friction coefficient, wear rate and fade resistance are checked batch by batch, not by sampling one run per month.
Vehicle Fitment
815080-1387439-brake-disc is listed for 1 brand and 2 model lines. Confirm by axle type and OE number before ordering — the same pad or lining can differ by axle variant.
| Brand | Model lines | OE refs |

| DAF | (432 mm front, rear axle) | — |
Technical & Material
The shoe platform is precision-cast grey iron, with a friction lining riveted (or bonded) to the platform. Lining formulations are available in semi-metallic and NAO (non-asbestos organic) compounds. Stable friction coefficient across a wide temperature range, strong resistance to thermal fade, and drum-friendly wear that protects the brake drum surface. Supplied as a complete assembly (platform + lining) for fast, workshop-friendly replacement; the lining can also be replaced separately to reduce costs. Key dimensions: Ø432 mm x 45 mm (internally vented), total height 130 mm, weight ≈35.8 kg. Manufacturing is carried out under IATF 16949 quality control, with ECE R90-compliant options available for EU-bound volumes. The same compound is supplied against 1 brand application. Compound selection (semi-metallic, low-metallic or ceramic) is fixed per part number, so repeat orders match the first shipment.
Installation & Maintenance
Before fitting, clean the drum and shoe contact surfaces and inspect the return springs and adjuster. Set the correct shoe-to-drum clearance, then bed in over the first 200–300 km avoiding hard braking. Replace shoes in pairs (per axle) and at the wear limit to keep braking balanced. For 815080-1387439-brake-disc, keep the old unit until the new one is seated; matching the marking avoids a second strip-down.
Ordering
Minimum order quantity 100 sets. Reference price: $25 – 50 / pc. Neutral or SAITE Friction-branded packaging available; customs documentation and CO issued on request.
