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.Dealer probably meant don't mess with it........yet.
Is it possible the dealer was confused with ATF instead of brake fluid?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.
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.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.
My main objective was to have the dealers service remove the existing brake fluid and put in new fluid. If it requires a flush - fine. I don't care how they do it as long as it's an approved method. Based on what the service writer said over the phone they don't do it per Mazda. It's possible she just sets up appointments and doesn't know what she's talking about.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
Remember that many drivers accelerate and brake more aggressively than others. The mileage and time mean nothing if the number of aggressive actuations is high. I see drivers every day who are accelerating toward a stop sign or red light, and then slamming on their brakes at the last couple of seconds. Their pads will not last nearly as long as my pads will. Also, some people live on steep hills which guarantees more brake wear.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
tight? Is the braking system completely sealed and not open to the atmosphere at all?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.
But only if an equal volume of air enters the reservoir. Otherwise there'd be a vacuum and it couldn't draw-down the brake fluid.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.
