FAQ: Technical Terms and Buyer’s Questions
Q1: What are the key material choices for brake drums?
A1: The most prevalent grades are high-strength gray cast iron (GG25), spheroidal graphite (SG) iron, and advanced composites for extreme duty cycles. Material selection governs wear resistance and regulates thermal expansion during repeated brake cycles.
Q2: How does drum diameter affect braking performance?
A2: Larger drum diameters allow greater braking torque and cooling area. For trucks, diameters typically range 350–410 mm, balancing space and stopping power (see above parameter table).
Q3: What are the typical installation and alignment standards?
A3: Drum hubs must comply with GB/T 34402, SAE J431, or ECE R90 for concentricity & radial runout (<0.06mm permitted). Correct torqueing of fixing bolts (see manufacturer spec) is crucial for safety and service life.
Q4: What determines the service life of brake drums?
A4: Drum life depends on material grade, surface finish, duty cycle, and ambient conditions. Quality products offer >300,000 cycles under mixed fleet operations, validated by ISO and fleet field testing.
Q5: Are customized surface treatments available for corrosion resistance?
A5: Yes, options include anti-rust paints, e-coatings, and powder plating. For “brake drum in China” applications in coastal or chemical plant environments, special finishes can extend lifetime by 2-3x.
Q6: What are the main testing methods used before dispatch?
A6: Every batch undergoes ultrasonic flaw detection, hardness check (Brinell), and dynamic balancing per ISO 9001 & FMVSS 121 regulations.
Q7: How are truck drum brakes maintained to prolong brake drum life?
A7: Key practices: Regular inspection for heat spots, timely relining of pads/shoes, and maintaining dry, debris-free contact surfaces. See manufacturer’s O&M guides for specific interval recommendations.
