Main materials:
--The brake drum is made of brittle gray cast iron material. The brake drum is a cast iron piece, shaped like a bell-shaped drum, fixed to the tire and rotating at the same speed as the tire. The HUB (wheel hub), brake discs, and brake drums are all made of gray cast iron material
Regarding brake shoes:
--The shear area and shear strength test of each finished brake shoe fully reflect our responsibility for customer safety.
--The length of the brake pads for the same brake is different, and depending on the role of the leading and trailing shoes in the braking process, the lining of the trailing shoes is shorter than that of the leading shoes
Self-adjustmen:
Automatically adjust the gap between the brake shoes and brake drums, and always maintain appropriate brake clearance
Regarding anti-corrosion performance:
--The surface has a rust-resistant coating and good corrosion resistance.
Excellent design:
--Product Upgrade: Adopting the latest BD3 technology, compared with the old model, the product performance remains unchanged, the weight is reduced and the load capacity is enhanced.
