Break fluid servicin?

Brake fluid should be changed every two years, are you asking about a main dealer or an independent?
 
Mercedes sytner bristol cost me 65 pounds brake fluid service only
 
£85 for a c63.
 
1L of dot 4 plus is £11 plus the vat genuine fluid for MB Parts and it takes half an hour tops to do.

Does it actually need to be changed every 2 years? Apparently most US manufacturers have stopped recommending regular changes.

It is hygroscopic. If you keep changing it the brakes won't suffer vapour lock and the brake system internals will last forever.

If you don't...

Yes, but it can be tested for water content. Apparently changing it every 2yrs is as pointless as 3000 mile oil changes that Americans insist on doing.

I've got a 30 year old Mazda RX7 with original callipers, seals and everything. All working fine. No problems for the future either that I can see.
Brake fluid changed by me every 2/3 years or so. Fluid cost is next to nothing, it's just the time.
PS Don't forget the hydraulic fluid if you have a manual hydraulic clutch.

You can only test the water content at the reservoir in the engine bay.

But brake fluid does not circulate much, there is no circulating pump, and in fact the reservoir simply tops-up the calipers as the pads move inwards due to wear.

There is some up-and-down action when the calliper pistons go in and out, but other than that brake fluid (slow) movement is pretty much one-way: from the reservoir down to the callipers.

You can easily see this when replacing the brake fluid, the reservoir might be crystal clear but the first batch of fluid coming out from the bleed nipple will be murky.

As for change intervals... some manufacturers say 2 years, other say 3 years... brake fluid is made to industry standard specs so this clearly demonstrates that it is not an exact science.

But the general advice is to follow the vehicle's manufacturer's specifications, which for MB cars is 2 years (as already said by others).
 
My local dealer used to do SBC changes for the same rate as normal (£85 at the time) - they acknowledged they were effectively making a loss on every one.
