Engineered for Class 7–8 commercial tractors, dry vans, flatbeds, and heavy-duty vocational trailers operating across North America, these 1308 Brake Linings provide a dependable friction reline solution. Specially configured to fit standard 1308 profile foundation brake shoes on 16.5" x 7" drum brake assemblies, this friction block set delivers stable stopping power, exceptional heat fade resistance, and uniform drum wear across demanding long-haul and regional distribution corridors.
Maintaining consistent braking torque and meeting strict FMVSS-121 standards under heavy gross axle weight ratings requires commercial-grade friction materials that withstand sustained thermal loads. High-mileage line-haul operations and intense stop-and-go duty cycles place severe demands on foundation brake friction, where inferior compounds cause glazing, rapid thickness decay, and aggressive drum grooving.Our 1308 Brake Linings deliver OEM-level dimensional accuracy and heavy-duty mechanical reliability tailored for North American fleet operations.
High-Density Non-Asbestos Friction Formulation
Formulated from premium eco-friendly, low-metallic non-asbestos materials, each 1308 friction block undergoes high-pressure molding and controlled thermal curing. This advanced composition maintains a balanced friction coefficient across operating temperatures reaching up to 750°F (400°C), mitigating high-temperature brake fade during steep descents and continuous heavy deceleration.
Precision Hole Pattern & Drum-Friendly Wear Profile
Each lining block features factory-drilled, chamfered rivet holes that align perfectly with standard 1308 brake shoe steel skeletons, ensuring secure mechanical fastening and high shear resistance under severe torque spikes. The optimized friction matrix promotes uniform contact across standard 16.5-inch commercial brake drums, significantly reducing localized hot-spotting, drum scoring, and premature edge taper.

Frequently Asked Questions (FAQ)
Q1: Which brake shoe models and axle setups are compatible with these 1308 Brake Linings?
A: These friction blocks are engineered specifically for North American commercial drum brake setups utilizing 1308 profile foundation brake shoes on standard 16.5" x 7" steer, drive, and trailer axles.
Q2: What friction formulation is used in these 1308 Brake Linings?
A: They utilize a heavy-duty, low-metallic non-asbestos organic (NAO/semi-metallic) formulation engineered for 20,000 to 23,000 lbs GAWR commercial vehicle applications.
Q3: Are rivet holes pre-drilled in the lining blocks?
A: Yes. All 1308 lining segments come precision-drilled and counterbored to match OEM rivet patterns for seamless installation on standard 1308 steel cores.
Q4: How do these linings perform under severe downhill and high-heat braking conditions?
A: The friction material is post-cured under high temperature to prevent brake fade and glazing, ensuring rapid thermal recovery and consistent stopping torque during severe duty cycles.
Q5: Can you provide customized packaging, part number stamping, and palletized bulk shipping?
A: Yes. As a direct manufacturer, we support custom edge-code stamping, private-label boxing, and export-grade pallet packaging for North American parts distributors and fleet suppliers.
