Ever wondered what's inside a hydraulic disc brake caliper?
We thought it'd be cool to open one up and show you the magic, or lack of depending on how you look at it.
A fluid, D.O.T or Mineral oil, is forced through the hose from the lever to the caliper when the brake lever is pulled and applies pressure on to the piston, the small round black disks in the image. As the pistons are pushing inwards towards each other they apply a clamping force to anything between them (hopefully a brake rotor and brake pad set!)
We tried to show you the caliper in stages of disassembly so that it was clearer to see which part comes from where. Hope you enjoy it.
Is there anything else you'd want to see pulled apart?
