Brake hoses on service schedule

[w824gb3]

So according to the service shedule the Disco Sport requires all new brake flexi hoses at year 6. Why is this? Never had a car before where these required changing during a routine service.

Came across this if it helps : "The estimated life of a typical 'rubber' brake hose is 6 years, according to BrakeQuip, the manufacturer of aftermarket rubber and high-performance stainless steel braided brake hoses."

Brake hoses aren't intended to last the life of the vehicle - they will perish and degrade in performance over time.

The only reason I can think that they have made it onto a service schedule is if there is an active braking system on the car that is monitoring the hydraulic stiffness of the brake system as one of it's diagnostics. Degraded hoses could conceivably reduce the braking system stiffness sufficiently to falsely trigger an issue with the brake system, so the service schedule includes the hoses in order to maintain functionality.

But it's probably just a money spinning exercise to add extra jobs at routine intervals - I sincerely doubt the original hoses, if manufactured to a high enough standard in the first instance, will be sufficiently degraded in 6 years to require replacement.
