Brake reservoir cap 162/03143 JCB, aftermarket

For the JCB machines: brake reservoir cap 162/03143, an aftermarket part.

Caps differ in thread or snap fitting, diameter and, on some models, a level sensor connection. A cap that does not match sits loosely on the neck and leaks, while a cap without a sensor on a reservoir that needs one disables the low level warning. When the cap is changed, check that the inner seal and the vent are clean and keep dirt out of the open neck. Keep the cap clean every time it is opened and top up from a sealed container where possible, so that as little moisture as possible reaches the fluid. A cap seal that has hardened or torn is replaced together with the cap, rather than refitted again.
