Brake Fluid change

[Nitro]

Hi guys,
After reading up a bit more about this recall thing, I have decided to have the brake fluid changed and the ECU checked up as well.
Any tips on which brake fluid to go for? Or if the local dealer hasn't got a replacement Hydraulic ECU so where to buy it from a reliable dealer in the states?
As always any tips and advice will always be welcomed

Your dealer will have the required Hyundai DOT-4 brake fluid. They will also be able to order the HECU for you if not in stock, but it is quite expensive. According to the TSB, about 5 12 oz containers are needed for a complete flush, but maybe more. The part number is 00232-19053.

To buy parts online from authorized Hyundai dealers, you can Google "Hyundai parts online" find several websites. You can also call them to ask questions.

If you are looking for brake fluid replacement, any DOT 3 or 4 will work fine. Lucas, Valvoline and Penzoil are some good brands.

Genesis sedans produced from April 30, 2008 to March 28, 2012 were recalled by Hyundai to have the DOT-3 fluid replaced by DOT-4 fluid. This was an official recall under the auspices of the National Highway Traffic Safety Administration (NHTSA). After March 28, 2012, the cars came factory filled with DOT-4.

So I would say that the comments above are absolutely incorrect to all first generation 2009-2014 Genesis models. Further, I personally would only use Hyundai DOT-4, since the reason for the change was provide better corrosion resistance to the Genesis HECU (anti-lock braking system) which experienced brake failures when their internal valves became corroded using the DOT-3 fluid. Supposedly, the Hyundai DOT-4 has anti-corrosion additives that the DOT-3 does not have.

I'm using Motul RBF 600 fluid as it has a much higher boiling point than the OEM stuff. I ran a track session at Thunderhill with zero fade.

According to Hyundai, the DOT-4 replacement fluid has certain anti-corrosive capabilities that the DOT-3 did not have. This is important because the HUCU is prone to valve corrosion, causing brake failure. I don't believe that it had anything to do with boiling point.

IIRC, DOT-4 absorbs less water than DOT-3 which also helps with boiling point, and has an anti-corrosion additive.

Edmunds has a version of the Hyundai press release referencing the additive:
http://www.edmunds.com/car-news/2009-12-hyundai-genesis-recalled-to-replace-brake-fluid.html

Not sure if the Motul fluid is a wise choice for the daily driver... The very amazon top review says it is strongly hygroscopic... which is the exact problem that the recall was issued for in the first place.
"The only downside is that like many ultra-premium brake fluids, it's very hygroscopic (moisture-absorbing) so you have to change it regularly to prevent corrosion in your brake system."

Here was the recall TSB for replacement procedure for those who are interested:

DOT 4 is more hygroscopic than DOT 3, which is why DOT 3 remains a lot of factory fill for cars today, including the Corvette. Brake fluid is a forgotten fluid, like powering steering fluid, we tend to only look at it when there is a problem.

Dry boiling point reference is a nearly useless specification in anything outside of a track only car. For a point of reference, flushed my brakes, used a virgin can of Pentosin Super DOT 4, then took a four day trip to the Tail of the Dragon. When I returned, checked the fluid with the litmus strip and it was already contaminated with moisture.

Motul RBF 660, while having a very high dry boiling point, has a significantly low wet boiling point. If you want a performance oriented brake fluid, I suggest Castrol SRF, it's dry is a little lower than RBF 660, but it's wet boiling point is almost 100 degrees higher.

 

[Mark_888]

Hyundai and the NHTSA have both said that the Hyundai DOT-4 has "anti-corrosive" properties designed to address the specific "problem" with the Continental HECU internal values that corrode too easily. At some point in the Genesis production run, the HECU's where fixed by Continental so they no longer had that problem with the valves.

I just don't see why anyone would want to take a chance if their HECU was within the production dates I mentioned above as having the problem. In fact, I would use the Hyundai branded DOT-4 for all first generation Genesis sedan models. This is one area where it is not safe to mess around.

I take the car out only on weekends so in the past 1 month so I havent even done 100 miles on it yet.
Anyway, I went to the dealership and they did have the Dot-4 original brake fluid in stock but they couldnt quote me a price for the HECU. I figured if I am having the brakes flushed, I might as well find out the price for the HECU and if it is within a reasonable price bracket, I might as well have that replaced as well you know, peace of mind and all that. But they didnt have that in stock and strangely enough they couldnt even quote me a price for it. So I just got the brakes checked and ordered a few car covers (for the underside) and came back. Now I want to get the price for a HECU and I googled Hyundai Parts Online and got a zillion online stores. So which one is a good reliable online store to shop from for Hyundai Original Parts?

Ok Update :
I found this part number online which seems to be it, but one says without smart cruise, whatever that means. Both are the same part number and price though.

http://hyundaipartsdepartment.com/parts/2011/Hyundai/Genesis/index.cfm?siteid=217704

That works out to about 7173 AED here in the UAE (freight not included) and while searching I found a person who deals in Genuine Hyundai Spare parts and he quoted me 7000 AED for the exact spare part number
so its cheaper here by a bit.

Edit : This website is giving it for cheaper, it says OEM, is it the same thing? http://www.hyundaioemparts.com/oe-hyundai/589203m0a5
So is this one : http://www.jimellishyundaiparts.com/productSearch.aspx?searchTerm=589203M0A5
And another one : http://www.hyundaipartsdeal.com/genuine/hyundai-hydraulic-module-assy~58920-3m0a5.html

The dealership workshop mechanics werent too happy about me asking them to replace the HECU and the Brake Oil for some reason. They kept on saying oh why mess with it when theres nothing wrong with it and have you had a brake light error yet (which I havent thank god) but when I was adamant that no I need to get this done for my peace of mind (after all my family travels with me usually you know) so they ended up saying, if we flush the brake fluid and replace the HECU, who knows something else will pop up, i.e. its an electronic car and you might develop some other problems. I would have thought its a pretty straight forward job of taking out the HECU, installing another one in its place and then flushing the brakes. Advice?

That is probably b/c the HECU unit itself is close to $3K in price. My brakes went to the floor when getting off interstate about a month ago. I was able to stop after pumping the brakes but made a direct route to dealership and they replaced the HECU and brake fluid for no charge. Note, I was only a few miles from the dealership...car was completely unsafe to drive and I would normally have not chanced it if not only a few miles away. I drove in 1st gear with my hazards on to the dealership.

My bill was over $3,200 covered by warranty. My vehicle did not apply to the recall...build date was May 2010. No warning signs or anything...just failed without any lights on the dash. Dealership has been great to me which is why I am still giving the car a chance

I just bought 2 12 ounce bottles of Hyundai brake fluid on Amazon for $18. I found stainless front brake lines from StopTech for $69 bones, plus I bought a bleeder bottle for $15. I'm ready to find out what this great brake pedal feel is like with stainless lines installed.

According to the TSB (13-01-006) BH Genesis sedans produced from April 30, 2008 to March 28, 2012 were included in the Mandatory Brake Fluid campaign.

Dealers were required to perform this Service Campaign on all affected vehicles prior to customer retail delivery and whenever an affected vehicle is in the shop for any maintenance or repair.

Later, there was an official recall issued in conjunction with the National Highway Traffic Safety Administration (NHTSA). The difference between a service campaign and recall is that owners must be notified of a recall, whereas a Hyundai mandatory service campaign is only done if the car is brought to the dealer for some other service or reason. So if you were not in the recall, that means that the Fluid Change to DOT-4 TSB was already done previously.

Note that the DOT-4 fluid change did not "fix" the problem, it only slows down the corrosion of HECU valves. The only permanent fix is a new HECU which has a different coating on the internal valves that are less subject to corrosion.

Replacing the HECU and flushing the brake fluid through the HECU is not a routine task, and they probably have never done it before. Working on brakes can be dangerous if a mechanic does not know what he is doing.

You should make sure that your mechanic has a copy of TSB 13-01-006 that explains how to flush the fluid through the HECU. But not sure if other countries use the same TSB's, and obviously the one I am referring to is in English.

If your build date is late enough, you may already have the revised HECU which is not subject to corrosion, so I would check on that.

Hi, first post. I have a 2013 R-spec sedan. I'm thinking of changing to Ate Typ 200 DOT 4 Normal Viscosity Brake Fluid, but I don't know if my car uses low viscosity. From what I've read, if the car has DSC, it needs low viscosity. Does my car have DSC? I know it has ESC but I'm not sure if that's the same thing. From the description, it sounds like what BMW calls DSC is what Hyundai calls ESC. If that's the case, then what's a good low viscosity DOT 4 fluid?

I'm using Motul RBF 600 fluid as it has a much higher boiling point than the OEM stuff. I ran a track session at Thunderhill with zero fade.

Motul RBF 700 is the bomb. Highest boiling point.

I just had the latest recall of brake fluid that changed the filler cap from dot4 to dot5 and also it changed the owners manual. yet, I see many posts that say dot5 should not be used with abs cars as it will harm that system very badly to the point of complete failure.

 

[Gunkk]

DOT 3 to 4, not 4 to 5. DOT5 is silicone, and is not compatible with our cars.
