Gasket Toric pump brake BirelArt

The tank is screwed into the body of the pump. Between these two rooms is an O-ring (O-Ring) or a sealing washer that does all the work.

• The role of fixing: Hold the tank integral with the pump while ensuring perfect sealing to prevent air from being sucked into the circuit during the pumping phase.

• Fragility: The tank threaded tip is often plastic. If you force too much, you risk breaking plastic in The body of the pump (very difficult to extract).

The 22SR EVO piston is a precision piece. Unlike appearances, it's not just a metal cylinder. It is machined with extremely low tolerances to allow the joints (cups) to slide without flee while generating a constant hydraulic pressure.

• The evolution "EVO": It guarantees a surface finish (polishing) optimized to reduce friction and increase the lifetime of the cups.

The Revision kit for diameter brake pump 19 mm is a complete set of original repackaging (Original Freeline Racing Parts). It is essential for restoring absolute sealing, hydraulic pressure and reactivity of your rear brake master cylinder or 19 mm.

As shown in detail the reference photo 12856.jpgThis all-in-one kit brings together all the hardware and internal wear parts necessary for professional refurbishment. Rather than replacing a complete master cylinder, this package of factory parts allows you to eliminate pressure losses, liquid leaks at the pedal and the phenomenon of "spongy pedal" that spoil your chronos on the track.
