Seals and cups are critical sealing components in brake master cylinders that prevent fluid leakage and maintain hydraulic pressure for safe braking.
Seals and cups are elastomeric or polymeric components installed within brake master cylinders to create fluid-tight barriers between moving pistons and stationary cylinder walls. They prevent hydraulic brake fluid leakage, maintain system pressure integrity, and ensure consistent brake pedal response by sealing the primary and secondary chambers of the master cylinder.

Common causes include brake fluid contamination, excessive heat degradation, improper installation damage, material aging from ozone exposure, and incompatible fluid chemistry causing swelling or hardening.
There's no fixed interval, but seals should be inspected during brake fluid changes (every 2-3 years) or if symptoms like soft pedal, fluid leakage, or pressure loss occur. Preventive replacement during master cylinder overhaul is recommended.
