Seal – Brake Piston

Description

Brake Piston Seal is a critical component in disc brake systems. It serves a dual purpose: sealing the piston bore and retracting the caliper piston after brake application. Here’s a breakdown of its compatibility, functionality, and importance:

Compatibility:

• The Brake Piston Seal is compatible with disc brake calipers used in various vehicles, including trucks.
• It works alongside other brake components, such as brake pads, rotors, and caliper pistons.

Functionality:

• Sealing Function: The seal prevents brake fluid leakage from the piston bore, maintaining hydraulic pressure during braking.
• Retraction Function: After applying the brakes, the seal retracts the caliper piston, creating clearance between the brake rotor and the brake pad. This clearance prevents continuous contact and excessive friction.

Importance:

• Safety: Proper functioning of the Brake Piston Seal ensures efficient braking performance, preventing accidents and ensuring driver safety.
• Heat Dissipation: By allowing the piston to retract, the seal prevents brake drag. Brake drag can lead to overheating of the rotor, causing deformation and reduced braking effectiveness.
• Longevity: Regular inspection and replacement of the seal contribute to the longevity of the brake system, minimizing wear and tear.
