Frequently Asked Questions

  • What is the difference between an automatic brake adjuster and a manual adjuster?

    Automatic adjusters set the brake clearance by themselves.
    With manual adjusters, mechanical adjustment must be done at certain intervals.
    The automatic system reduces maintenance costs and always maintains optimum braking distance.

  • Are 3MG brake adjusters compliant with OEM standards?

    Yes. 3MG adjusters are manufactured according to international OEM quality standards, offering long-lasting performance with high-strength materials and precise production processes.

  • How can I choose the correct adjuster?

    Knowing the following information ensures the correct selection:

    • Vehicle brand / model

    • Drum diameter

    • Camshaft type

    • Arm angle
