At every service, in the online "servicing information" where it lists the servicing requirements for each year, brake fluid change is only ever mentioned for F-Types with ceramic brakes. For other F-Types it states "Check brake fluid level is between Min and Max. Refer to the workshop manual for more information". Can anybody with access to the workshop manual tell me what the information is? When I questioned why the brake fluid has not been changed the workshop manager ( official jaguar dealer) said they check the moisture content of the fluid and if it is below a certain percentage it is not required. I am now wondering if there is an absolute Max time limit when the fluid must be changed, or is it OK to just keep checking the moisture content.

My service schedule states brake fluid change every 3 years or 48,000 miles, whichever comes first

The change is required due to moisture content or colour deterioration - the pen type devices are cheap enough and adequately accurate - you can soon do all your household and the neighbours 🙂
3 years is an “average” time between changes - there is no time default. You see recommendations vary between 2 and 4 years usually.
A moisture and visual check is the sensible way to determine, and if you do a high mileage it’s a good job to include with a pad /sensor / disc change anyway.

My independent changes brake fluid when it needs doing, not by time - he doesn't like me wasting money, even though he'd get it!

My car’s servicing schedules are the same i.e. brake fluid change is only mentioned for F-Types with ceramic brakes and for mine it states "Check brake fluid level is between Min and Max. Refer to the workshop manual for more information.”

I’ve attached the ‘F-Type (X152) Maintenance Schedules’ (and plenty more) which is applicable to the Jaguar F-Type 5.0L and 3.0L supercharged engines only and is to be used in conjunction with the maintenance check sheet. Brake fluid info is on page 4 (Replace brake fluid every 3 years).

Personally, I think 3 years is a bit too soon to change the brake fluid especially if you’re doing low mileages. It’s a good idea to periodically check the pH and moisture content of the fluid. Discolouration (darker) is an indicator that it needs changing.

I’m only doing around 3,500 miles per year so providing the brake fluid tests are ok, I’ll probably change it every 4 to 5 years.

Many thanks for the maintenance schedule...It’s extremely useful for me. Brilliant 👍🏻😊

You can download the service schedules for your car if you go to osh.jaguar.com and enter your VIN.

Cheers 👍

Plenty of additional information with it, which should be used in conjunction with the maintenance check sheet (Jaguar service schedules) on https://osh.jaguar.com/

I'm surprised the two year interval is controversial.

Here in the US, at least among sports car enthusiasts, changing the brake fluid every two years is the overwhelming norm.

Since brake fluid absorbs moisture regardless of use/miles driven, it seems to makes sense.

Water in your brake fluid leads to corrosion, which is not good at all.

Anecdotally, it would seem like parts of the world with higher moisture/precipitation levels would be subject to more concern for brake fluid change intervals, as opposed to arid regions.

Just my 2 cents worth....

I had an old Ford Escort where I hadn't changed the brake fluid for more than 5 years. From my experience it can go off quickly and change from having OK brakes to a sinking pedal and brakes only on one side etc. Scary stuff. Not worth the risk for something pretty basic.
