AP Racing Caliper Recertification

How certain are you that your current brake calipers are performing optimally? If you're basing caliper condition on visual inspection and simple mileage calculations, you're missing the critical data you need to make an educated caliper replacement recommendation. You're also potentially leaving performance on the table.

How badly has a season of green flag racing fatigued your calipers? Are they experiencing any pressure drops as a result? Are the caliper pistons telling you the full story with a quick visual inspection? Do you really want to be covered in brake fluid trying to find out, or would you rather be doing something cleaner and more productive?

Why not let Essex do your dirty work, and give your calipers a clean bill of racing health through our new Caliper Analysis and Reconditioning Service? Essex will deconstruct your calipers and put them through a rigorous inspection and rebuild process:

  • Rockwell Hardness Test- Your calipers will be tested for hardness against the standard for that particular caliper type as sold new. This test will give you a relative understanding of how much fatigue and stiffness loss your calipers have experienced. Tired calipers lead to pad tapering, increased pad wear, leaky seals, and a loss of pedal firmness, all things you want to avoid. Essex will make a replace or rebuild recommendation based on the results of this test.
  • Rebuild- After passing the hardness test, all serviceable parts of the caliper will be inspected and replaced if necessary, including the seals, wear plates, pistons, piston caps, bleed screws, and O Rings.
  • Cyclical Pressure Testing- After your calipers have been rebuilt, they will be cycled at high and low pressure on a pressure bench to ensure proper functioning. This is important, as certain leaks only show up under specific pressure conditions.

Essex is AP Racing's only authorized caliper rebuild center in the USA, and we have the tools and equipment to evaluate the true wear and tear on your parts. Our skilled technicians are trained to ensure your calipers make it back to you quickly and in peak condition. Don't waste money on new parts you may not need, and make sure you're getting the most out of the ones you already have.
