Gasket Toric pump brake BirelArt

The Liquid tank for brake pump 22SR is a spare part of origin manufacturer (Original Freeline / Birel Art). This jar is specially designed to power the master cylinder (brake pump) model 22SR that equips the braking system of the group competition chassis Birel 

The cup (or lip seal) is a wear part. Its role is to transform the pressure exerted by your foot into hydraulic pressure into the pipes.

• Symptoms of fatigue: "Spongy" pedal (which goes down to the floor), liquid leakage at the bellows (cap), or braking loss during high heat phases.

• The material: These joints are EPDM (ethylene-propylene-diene monomer) to withstand the brake fluid. NEVER USE STANDARD JOINTS Hardware stores, they will disguise in a few minutes in contact with the liquid.

The Circlip Birelart is a critical safety piece for your braking system. Its role is to lock the axis that crosses the brake pads inside the stirrup. Without it, the intense vibrations of karting could slide the axis, resulting in the loss of the pads and a total braking failure.

Made of high quality spring steel, this "wire" circlip has a calibrated voltage to stay lodged in the throat of the axis, even under the most severe constraints encountered in competition.

On a 22SRR pump, you find O-rings at different locations (tank hose entrance, fill cap, sometimes as guiding joints).

The most important point: The material. The seals used in hydraulic braking must imperatively be in EPDM (ethylene-propylene).

• The danger: If you are using a "standard" O-ring (often in NBR / black nitrile bought in DIY store), it will swell, disintegrate and pollute your circuit in less than a few hours in contact with the Brake fluid DOT 4 /5.1.
