Critical sealing components in brake calipers that prevent contamination and maintain hydraulic pressure for reliable braking performance.
Seals in brake calipers consist of two primary components: the dust boot (or dust seal) and the piston seal. The dust boot is an external flexible seal that prevents dust, moisture, and debris from entering the caliper bore, protecting internal components from contamination and corrosion. The piston seal is an internal elastomeric ring that creates a hydraulic seal between the piston and caliper bore, maintaining pressure during braking while allowing slight piston retraction to prevent brake drag. These seals work together to ensure consistent brake performance, prevent fluid leaks, and extend caliper service life under extreme temperature and pressure conditions.

The dust boot is an external seal that prevents contamination from entering the caliper, while the piston seal is an internal seal that maintains hydraulic pressure between the piston and caliper bore.
Typically during brake pad replacement or every 2-3 years, but always inspect for cracks, hardening, or fluid leaks. Many manufacturers recommend replacement every 60,000-100,000 km.
No, seals should never be reused as they lose elasticity and sealing capability once compressed. Always install new seals during caliper service.
