Frequently Asked Questions
|
Q1: |
What is a zinc plated brake balance weight used for? |
|
A1: |
It counterbalances rotational weight on brake drums, discs, and wheel assemblies, eliminating vibration for smooth, quiet braking in passenger cars, trucks, and trailers. |
|
Q2: |
How long does zinc plating last on brake balance weights? |
|
A2: |
With controlled plating thickness, our weights pass 48–96 hour salt spray testing, suitable for coastal and heavy road-salt conditions year-round. |
|
Q3: |
Which is better, zinc plated or adhesive brake balance weights? |
|
A3: |
Zinc-plated clip-on types suit steel wheels and high-temperature applications, while adhesive types fit alloy wheels. Choice depends on your wheel design. |
