🔧 Brake Safety & Install Tips

  • Professional Install Advised: If you are unsure about working on brakes, please use a professional garage—incorrect installation can cause total brake failure.
  • Use Fresh Fluid: Never reuse old brake fluid. Always bleed the system with a fresh, sealed bottle of DOT 4 fluid.
  • Check Bolt Fitment: Aftermarket units can have slightly slimmer bolt holes. You might need new mounting bolts or washers for a perfect, secure fit.
