Front disc brake caliper seal and piston kit ️

This kit refreshes the hydraulic heart of your front brakes. It replaces the piston seal, dust boot, and related rubber parts that keep pressure inside the caliper and dirt outside. Use it when the pedal feels spongy, a wheel runs hot, or you see brake fluid mist around the caliper. Heat, moisture, and road grime age rubber—restoring it brings back firm pedal feel, straight stops, and quiet operation .

How it works

When you press the pedal, fluid pushes the caliper piston forward. The square-cut seal holds pressure, then flexes back to retract the piston slightly after braking. The dust boot shields the bore from grit and splash. A healthy seal keeps fluid in and air out, delivering stable braking and even pad wear ️.

What if it’s worn or broken

  • Fluid leaks or air ingress causing long pedal travel
  • Uneven pad wear, pulling under brakes, or vibration
  • Sticking piston, overheated rotor, and reduced stopping power
  • Risk of ABS warnings and warped discs if ignored ⚠️

Install tips from a pro

Clean the caliper bore; lightly polish corrosion. Use brake-clean only. Lube seals with rubber-safe brake grease, not petroleum. Seat the dust boot correctly, bleed the system fully, and torque guide pins to spec. Test for leaks and bed pads.
