Every 3yrs my local LR dealer presses me to replace the brake fluid on my FL2. I understand the quoted rationale re potential moisture ingress reducing the efficiency of braking, but is this a real risk averted or simply a revenue generating ploy by dealers?

Do you change yours that often? If not, what do you do?, Life is not a dress rehearsal!

every 4 - 5 yrs and by a local garage...
about €40 and 1 hour wait.
my motorbike €30
cheap enough to just do it

I change mine every two years. When you compare the colour of what come out with new fluid you realise that it is well worthwhile. Another benefit is that it gives all the hydraulic seals a better chance of surviving longer. An easy DIY job. John

It's a service item at three years, but not included in the service price. Was never changed on my last car as dealer insisted it wasn't necessary. This may be because they had to do the third service themselves at own expense to sell me the car. At least they stamped the book when I pointed out that it hadn't been done. That may not be quite the same thing! Fluid AND flexible hose change due at 6 years. Ex AA Series III LWB Safari - Gone

I'm a registered MOT tester and I've worked in the motor trade for 40 years. I have never, ever, changed a flexible hose unless it has been perished or cracked and I only change fluid when my meter tells me there is too much moisture present. I personally think those items are money spinners for main dealers. I have never seen a flexible hose fail in service but I've probably seen about 6-8 metal pipes that have failed due to corrosion. Past: FL2 TD4 HSE Auto

Well I have seen a flexible hose fail - on a 20-year old Jaguar - and it was a frightening sight I can tell you. Externally, there was no sign of any problem until someone pressed hard on the brake pedal - then what can only be described as a 'blister' formed on the outer rubber surface and brake fluid starting dripping from it. Clearly, under severe braking that hose would probably have split completely.

I've also had flexible hoses seize up internally on several of my classics (admittedly after very many years of service) resulting in complete loss of braking on one or more wheels.

On the whole, then, I would have thought replacement every 10 years is a sensible policy.

Chane it at correct intervals. You have a complex electronic/hydraulic ABS unit which costs well over £1000 to replace. Brake fluid is hygroscopic (absorbs moisture from atmosphere), do you want contaminated fluid passing through this unit. All FL2's (3) Gone

I can perhaps see the point of changing flexible hoses after say, 10 years or more but when any half-decent garage has a brake fluid tester that specifically tests for moisture content and it shows that there is none present, why change it?

I can just imagine the scene at the garage when a customer comes to collect their car after a service. " Hello Sir. We've done the service that you paid for, tested the brake fluid, it came up all clear but we changed it anyway as it's a nice little earner for us. That'll be an extra £40/50/60 that you didn't need to spend. Ker-ching!"  Past: FL2 TD4 HSE Auto
