Dealer probably meant don't mess with it........yet.
No, I pressed her on it. She said Mazda recommends against changing the fluid. Not sure if they only want it changed when the brakes are replaced or what.
I'll talk to a tech when I bring the car in next week. This is the only dealer I've ever encountered that refuses to do service.
They've been a Mazda dealer for at least 40 years. I've bought two Mazda's from them previously.
I agree with Arcticshade as usually people say brake fluid flush, but for our SkyActiv-Drive transmission we use drain-and-fill.I called to schedule my 16 CX-5 for service at the dealer. Among the things I wanted done was to drain/fill brake fluid. Mazda service person told me Mazda says not to mess with the brake Fluid? WTF
I have 24,000 miles on the ODO.
Thoughts?
That's ridiculous. It's well known that water in brake fluid leads to poor performance and possible failure of ABS components due to corrosion. Flush the brake fluid whenever water content is 2% or higher.
What do you mean by drain & fill? I flush my Brake fluid when I change brake pads which may be 3 to 6 years and never a problem. Ed
That would be too long an interval for me. At 7 years 70k my original brakes still had life in them. 3 years is a very good rule of thumb. You really don*t water ruining the ABS components over the long term. Fluid is much cheaper than a brake system failure![]()
I don't think moisture content is a big worry anymore since the system is tight. I've read that the bigger problem is additive breakdown in the fluid.
Yeah - can't wait until I ask the dealer to change the ATF fluid. That should be interesting.
tight? Is the braking system completely sealed and not open to the atmosphere at all?
The fluid level in the master cylinder goes down over time because pad wear allows the caliper pistons to move further inward, pulling fluid from the reservoir.
