Product Features And Key Advantages:

I. Comprehensive Vehicle Compatibility, One-Stop Disc Brake Solution

This trailer-specific brake disc and caliper assembly series is engineered for towable RVs, light-duty trailers, food trailers, camping trailers, travel trailers, flatbed trailers, camper trailers, park model RVs, boat trailers, utility trailers, motorcycle trailers, and farm trailers. The product line includes chassis wheel hub unit assemblies, brake discs, caliper assemblies, spindle assemblies, and complete axle assemblies, delivering a full range of wheel-end and braking solutions for diverse trailer applications.

II. Superior Disc Brake Performance With Excellent Heat Dissipation

The disc brake design offers significantly better heat dissipation and fade resistance compared to traditional drum brakes, ensuring stable and reliable stopping power under continuous braking conditions. Two bearing configurations are available to meet regional standards: the Australian version utilizes SL bearings (LM12710/LM12749 and L68110/L68149) with 0.8661" inner and 1-3/8" outer spindle diameters; the North American version uses L44649/L44610 and L68149/L68111 bearings with 1-1/16" inner and 1-3/8" outer spindle diameters. Each assembly is rated for 3500 lb per wheel, suitable for mainstream trailer braking requirements.

III. Premium Materials And Precision Manufacturing For Long Service Life

Brake discs are manufactured from gray iron casting G3000 material in a solid disc structure, providing excellent wear resistance and minimal distortion under high-temperature operation. Calipers are mechanical type with 89.5 mm mounting bolt spacing, and brake pads utilize semi-metallic friction material for consistent friction coefficient, extended service life, and low noise. Hub units are forged from high-grade iron for dense grain structure and superior impact resistance, finished with baked paint for robust corrosion protection in outdoor and harsh environments. Bearings are sourced from reputable domestic and international brands, and spindles (hub ends) are precision-machined to ensure smooth rotation and accurate axial alignment.

IV. Flexible Customization To Meet Specific Requirements

Headquartered at Shiao Trailer's factory in Taizhou, Jiangsu, this series offers multiple disc diameters, bolt patterns, and caliper options, with the common configuration being 5 on 4.5" bolt pattern. All parameters are fully customizable per customer drawings or specifications, including spindle size (bearing inner diameter), bolt pattern, load rating, bearing type, spindle diameter and length, axle tube shape, spring center distance, overall axle assembly width, axle tube inner diameter, spindle journal diameter, and compatible suspension type. Custom orders are accepted free of charge, ensuring precise fitment with existing chassis or modified setups.

V. Ample Stock, Fast Delivery, And Eleven Years Of Industry Expertise

Standard models are kept in full stock and ship immediately, while custom orders are fulfilled within a 15-day lead time. Packaging consists of iron frame pallets and individual neutral cardboard boxes to prevent transit damage and corrosion. Taizhou Shiao Auto Parts Manufacturing Co., Ltd. brings eleven years of specialized experience in trailer chassis components, backed by 24-hour technical support and after-sales service.
