Brakes - cure for brakes getting rusty and pitted

3818 Views 47 Replies 21 Participants Last post by  OkieBolt
I had to replace my brake rotors and pads twice by 42,000 miles. About every 20,000 miles due to rust and uneven wear. The problem was I did not use the brakes! Always used regeneration braking. After the second expensive brake job, i started to put the car in neutral going down a good hill, and used the brakes to slow me down. With the car in neutral, it ensured that the brakes were being used to slow the car. My last visit to the dealer for a tire rotation, i asked that they check and clean around calipers. The service tech came out and said the brakes were great and clean, what are you doing to keep the brakes in good shape. I told him about using neutral on a hill occasionally, and the actual brakes used. Keep it up, it works, your brakes look great.

I dont live in climate with salty roads.

Driving in Neutral in most states is illegal.

We have a Volt with ~90k miles and the brakes look new. TX and OK car. Climate makes a huge difference.
Agreed, using your brakes once in a while is actually good for them and you.

I am surprised the number of times I have had to use the brakes because someone has pulled out in front of me. I am beginning to think my car is invisible, maybe some kind of cloaking device I don't know I have.

I will disagree with you on this. New Semi’s use what is called E coast ( neutral) with automated transmissions and are legal in all states. For as long you are not driving under speed limit on interstate and not causing operation of your vehicle in motion to be stopped by state trooper.
You will experience this if you drive after new Semi’s that they constantly changing speed and accelerate if there is hill coming.
You can research IPM Detroit transmission and it will help you understand that e coast ( neutral) is bringing 4-7% better MPG.

That is an automated system and I assume is transparent to the driver. You can disagree but there are laws against driving / coasting in neutral. Not saying I agree with the laws or there is any way for it to be enforced but it is still a law.
Does the Bolt regen in reverse? If not, running and braking in reverse occasionally could scrub the rotors, but won't help with the calipers.

My 2022 Bolt EV does regen in reverse when one pedal driving is on. I will sometimes turn it off when backing in order to activate the mechanical brakes.
X2 - it's all about the humidity where one lives and how stupid his state is to pour poisons on the roads. Low humidity, no salt on the roads, no brake problems. Our Bolt is almost six years old-and the brakes are clean, shiny and show every possibilty of being the most durable part on the car.

This!

I went to the state fair last week to man a booth. The local utility had an MME there and had to leave it overnight due to safety reasons (not being able to move the car with the crowds milling around). They ran the sprinklers overnight so on day 2, the car looked horrible, spotty from sprinklers, and rust on the brakes on the sprinkler side, shiny on the other side. The wheel spokes kept part of the brake surface from getting wet and was rust free as well. No doubt, the next day, the brakes were clean and shiny after a few miles of city driving.
I run my bolt in Southern Ontario, salt on the roads all winter. I currently have 145,000 km and see no damage to the rotors.
it’s a 2018, when I first got it I used to worry about that and look at the rotors every month or so. I gave up a couple years ago.
I never put it in neutral to use the friction brakes, or attempt any other means of scrubbing the rotors.
my understanding was the Bolt was designed with some sort of costing on the rotors to prevent pitting from lack of use.

This is a design defect and should have been covered by a warranty. Anybody interested in suing Chevy on this. At 36,000 mile the Romeo Chevrolet dealer wants $900 for a break job

No, it is not and no I doubt anyone is interested in suing. Tons of people with EV's have over 100k miles with original breaks that still look new and still work as new. The design flaw IMO is the driver not understanding how to maintain their vehicle.

Oh, and excellent first post to ask if anyone wants to sue GM. If you dont want to spend $900 on a brake job from the dealer, go somewhere else. They are just brakes. Or, do it yourself.
Location, location, location. In the salt belt in the middle of the snow machine of the Great Lakes there just isn't much you can do.
The brakes are usually a secondary consideration anyway, I'm lucky if my car hits 10 years without doing any body work.

Fixed that for you.

Have you added up 4 rotors and pads from rockauto? I bet it doesn’t total to a third of that estimate, and really, 25 minutes a corner, less, much less, if you are experienced. $181 and shipping. That said, I thought adaptive cruise shined them up as well.

Brakes for the most part are extremely easy to do. Especially if it is 4 wheel disk. Drum brakes suck. Rear calipers can sometimes be a problem depending on how the e-brake is setup. Sometimes there is a tool required to screw the rear caliper back in. Some cars like Porsche used a drum brake inside the rear disk as the ebrake and those pads almost never needed to be replaced.
Just feeling the brake pedal I think it goes down on parking brake application, so it may be integrated into the main brake system?

It is indeed a manufacturing defect. Rotors on any other vehicle done need replacing unless it’s a truck etc with heavy loads. Note there was no driving instruction in this regard when purchased. . And to get an auto manufacturer to recognize this is to be working against a power much greater and and and equalizing reliance on legal and regulatory means to bring about change has and will be a continuing way to get better autos on the road.
Sarcasm is really not appropriate.

Explain how it is a manufacturing defect? I have not checked, but I am sure that these same brakes are used on non-ev cars. Some people burn through brakes in 20k miles, others in the same car can go 100k miles. Climate also matters. The brakes dont fail. In some climates they degrade from corrosion. Guess what, Teslas have this problem too. I am sure plenty of ICE cars have brakes that corrode as well.

As far as instructions, have you ever had instructions when you purchased a new or used car? How many things have you purchased that you received instructions on use from an actual person. And what did you expect them to instruct you on? Washing your car regularly to keep road salts off?

I understand your frustration but you are calling something a defect that is clearly not a defect. I dont expect there are any attorneys that will take this case as there is nothing to be gained? What do you expect as a remedy? Them to buy your car back or just to replace the brakes for free?

As for sarcasm, this is the internet so I doubt it is the first time it has happened. And as I stated, your first post on this forum is about suing GM for defective brakes. OP who also is new received no such treatment because his post was straightforward about the problem and what he did himself to resolve the issue without involving litigation. Maybe be more like the OP and you will get less or no sarcasm back.
