Brake fluid change

2015 My car says I'm due for a change 08/2019. I only have 45,000 miles on the car. I drive mostly highway and because I have 2 cars I usually only drive this bmw 1 - 3 times a week (I would like to drive it more but I'm just lazy to take it out of the garage and other reasons for driving the other car more often)

My question is how important is it to change the brake fluid?

My other car is 12 years old and I has 145,000 miles on it and i have never changed the brake fluid. And it's working perfectly fine.

Will not changing the brake fluid damage any parts ?

Yes. The moisture eventually allows corrosion in the brake cylinders. Brake fluid avidity is a time function and not use, it starts as soon as the bottle is opened and unsealed.

I imagine the high-end labor rate in San Francisco is ~$200/hour, and you will be charged 1 hour equivalent to hook up the computer, 1 or 2 hours to do the actual work and a full parts container cost. About $750.

I was just talking to my shop about this and they said that the fluid should be changed out every two years, regardless of how many miles have been driven because the interval is based on how long the fluid has been exposed to moisture.

Had a truck that went for about 15 years without flushing the brake fluid (60,000 miles); when I went to change it the proportioning valve had rusted shut - bleeding the rear brakes was impossible and there was no brake action on the rear wheels. Moral: Change it every two years regardless of mileage!

This is a pretty easy DIY project if you have a Motive brake fluid bleeder. They are about $50 and will easily pay for themselves. There are several YouTube videos on how to do it.

BMW pulled a trick years ago. They changed the brake fluid change interval from two years to the first one in three years and then every two years. This saved BMW having to do a second brake fluid change during the old four-year free maintenance period. The clock on brake fluid starts running when the car is assembled, but the clock on free maintenance starts when the car is sold.

Yeah, prices in SF are higher than here in Bubbaville, Floriduh, but not THAT much higher. The BMW dealer I use charges $120, but often has $99 specials. With the proper equipment they can change the brake fluid without taking the wheels off the car. It takes about 15 minutes.

Thanks guys appreciate all the responses.

Called a few places for some pricing BMW of weatherford wants $329

Other local shops with great reviews who work on bmws and other euro cars gave me $150, $185, $118.

The $185 is a BMW specialist shop that works only on BMW

The $118 has the most reviews 5stars with over 200+ reviews. They also said they have the machine to do the fluid change.

Is this an easy job? I'll shell out $67 more just to know it's done by a specialist. But if it's an easy job that's impossible to make a mistake or do a bad job on I'll rather go with the $118 haha

(If your wondering why I didn't call BMW of sf it's because I let them work on my car twice and twice it came back with a scratch. The second time came back with shoe foot prints on the front bumper.)

LOL. BMW of Weatherford? California? I'm a retired hippie, born and raised in Santa Clara, and never heard of Weatherford, California.

Ahhh, Weatherford BMW of Berkeley!

My dealer is careful about stuff like that. But, I'm convinced that a lot of BMW dealers do stuff like that on purpose to encourage people to lease BMW's instead of buying them and keeping them for maybe eight or ten years. I'm thinking the same thing about scratching up the clear coats when washing cars, too.

My dealer also had a scratched clear coat problem. But, there was a white M2C in their showroom there the last time I was in, and it was scratch-free. The trick is to look at the reflection of the showroom's ceiling lights in the car's surface. I still have "DO NOT WASH" sings on my car when it goes in, though.

I wash and wax my car before it goes in for service. I tape up the top of the front fenders and top of the nose with blue 3M painter's tape. 3M makes a "delicate surface" version in the orange wrapper. That lets everybody at the dealership know that I'm an absolute **** about my car. It causes the service manager and service writer to pick the tech's who work on my car.

I recently changed my brake fluid - wrote about it in another F10 forum.

I have read numerous reports of experienced DIYers getting a soft pedal after doing standard two-man bleeding, only regaining a firm pedal after doing the full TIS/ISTA+ procedure. After reading so many accounts, I didn't even attempt the F10 without a power bleeder and bought one for the first time for this job ($80 Motive).

After observing all the stuff that ISTA does during the process, my short list of recommendations: 1/ you really want to use a power bleeder 2/ you really want to use ISTA (or equivalent) and follow the TIS procedure 3/ You will need 2-3L of brake fluid (not just 1). Most people make it with 2.

The ISTA procedure walked me through a pre-pre-bleed, a 15 second per axle pre-bleed, then a 100 second per corner final bleed, actuating DSC pumps and valves in many complicated patterns during the process while having an assistant pump the brake pedal every 5 seconds (as per TIS/ISTA). On the F10, it's way more than simply pulsing the pump once while the bleeder is open.

Change brake fluid every 2 years regardless of miles and regardless of year/make/model of car.

The bottom line is you should maintain your car like your life depends on it because it does.
