Product Description
Rear Master Cylinder Reservoir Diaphragm - Replaces Honda OEM 45520-300-000. This brake reservoir diaphragm seals under the master-cylinder cap while allowing brake-fluid volume changes as pads wear.
Use it when the diaphragm is swollen, torn, hardened, leaking, or no longer seals the brake-fluid reservoir.
