Do I have to change brake fluid?

Hi,

So..last time I visited my dealer, they suggested me to change brake fluid and engine oil. Right after I came back from the dealer, I went three body shop in my town. They all said I don't have to change brake fluid. I was confused because three of them told me not to change it.

Do I really need to change brake fluid?

Yes. BMW will pay for a brake fluid change 2 years after the car was first put in service and it should be repeated every two years.

What if you're out of warranty, do you still change the fluid?

Could you please rewrite this in standard English? It is really difficult to understand what you are asking.

If you are out of warranty you do not need to do anything. Just put gas in it and drive. No oil changes, no fluid changes, freak it.

And redline the engine in neutral right after you start it to warm it up faster!

Of course you should! change it every 3yrs/30,000 miles.

Why would a body shop know about maintenance schedules? Will they pay for any malfunctions due to not changing the fluid? Of course not. Yes, it does need to be done. Over time, brake fluid will become contaminated and absorb water which will degrade the braking system.

If you are no longer under the maintenance warranty, then feel free to have it done at a reputable indy BMW shop. It will probably cost less.

Agreed, although my vehicle has been alerting me to its service every 2 years.

I'm sorry to say, but I think you deserved some of the comments you received. Why would the fact that you're out of warranty negate the need for this service? Vehicle maintenance still needs to be done, whether it's for brake fluid, oil changes, wiper blades, microfilter, etc. That doesn't change now that it's up to you to pay for it.

Nope. Brake fluid (under normal use) is time based only. Miles are irrelevant.

BMW requires a brake fluid change every two years beginning with the production date.

The easiest way to do expensive damage to you brake system is to not get your brake fluid changed on schedule.

OP - I'd stay very far away from that body shop when it comes to mechanical advice.

How much typically at a dealer for a brake oil change?

All it takes is to drive the cost of a brake job into 4digit area is for the caliper pistons to get rust from moisture that has condensed out in brake fluid. You change the fluid at 2 to 3 year intervals and you can only have to expect new pads and rotors in the list of parts.

A little less than a new kanuter valve but more than muffler bearings.

I just did a brake flush last week. If you're out of warranty, I recommend 2 qts of Motul RBF-600 (~$20/qt). If you're savvy enuf to be on this forum, no reason not to spend a lil bit more for such an important part of your car, even if the standard brake fluid is prob fine.

I was quoted $100 for labor on flush only, but my actualy cost was different as I replaced rotors, pads, and upgraded to stainless steel lines.

Or RTFM and use the correct figure of every 2 years.

Dinan service charges $99 flat rate. Or at least they did the last time I went.

2 years is what BMW recommends when it's their dime, old school maintenance is every year.

Virtually every manufacturer recommends 2 year intervals. VW recommends a brake fluid change after 3 years and then every two years thereafter.

This has nothing to do with included maintenance.
