I have had my front driver side brakes make noise lately and when I was doing my oil change yesterday, I noticed the rotors are worn a lot on the inside but I never noticed them worn on the outside. I do have to change my brake fluid for sure. When I bought the car the previous owner har recently changed the pads/rotors. So it has been like 6 years since then. I just got a good deal on these front rotors so I pulled the trigger and ordered them last night. I plan on pairing these with Duralast Elite pads with a lifetime warranty from Autozone. Will be getting the same combo for the rear too. These front rotors will be delivered next week on the 15th.
Yeah I have some drill slotted dimpled a fancy things I don't know who makes them but they're like I never want to say anodized but they have something permeated into the pores of the metal kind of like dykem bluing. But it's made for corrosion resistance and it's about 3 or 4 years in on my two sets and they're still looking pretty much like new and these cars are dirt and trails quite a bit
Just got one of the front rotors in today. The rest should be in this week. So all around Brembo rotors with Duralast Elite pads.
All parts are in now and should be installing them next weekend. Front Brembo 09.B494.11 Rear Brembo 08.A534.31 Front pads Duralast Elite Rear pads Duralast Elite
Did the front brakes today and was planning on doing all four corners but ran out of time. Did not have a breaker bar and a bolt to push the rotors off the hub. As long as you have all tools needed this is a 1 hour job for the front. I watched the video from @NutzAboutBolts Everything went smooth and tomorrow I will do the same for the rear. I still kept the rotors as they can be turned. Anyone want buy them just let me know. The pads had like 1-3mm left on them. So annoying the screeeching. All should be good now and this should help stop any overcharging on regen.
Just some extra geek stats on everything. Previous owner replaced all pads/rotors with unknown brand and paid $319.90 for parts and $501.09 total with labor on 11/8/17 and front pads lasted 70,706 miles no warranty on parts on his receipt. I obviously got better parts and my pads have a lifetime warranty. I paid a total of $311.57 after saving with promo codes, gift cards from doing surveys and rewards points from my Prime credit card and savvy shopping. I will also still make 5% cashback on the rotors, so I saved $73.99 total before 5% cashback. Doing the job myself so I am saving labor costs too. Test drive went smooth but weather is bad so will do the rear later when the weather is better.
Description says it is the hub area and the rotor edges that are coated, not the brake pad contact surface. You can see the coating in the edge on pic above showing the cooling vanes. SM-G781V ?
I bought the same type of things but not the brembo brand by a company that specializes in coated rotors. It's some type of anti-corrosive material The stuff on mine was black and it was the whole rotor was done the hat the surfaces all of it and the company said that the coding wearing off the surface will not affect the pads It is some kind of something similar to anodizing. These are slotted dimpled rotors. They're on my generation 3 right now been on their 3 years The stuff wore off the surface and the rest of the rotor including the hat and the edge in between the two plates and the vent slots all still coated no problem for all four rotors and the at the time very decent ceramic pads Raybestos I think paid less that 250 for all . But this was also just before the pandemic
Did you previously have codes indicating something amiss with regen? The power management control ECU is in charge of monitoring the charging of the traction battery, and it prevents overcharging in *all* situations, no matter what pads/rotors are installed. The idea that the vehicle makes up for failing/insufficient friction brakes by increasing regen may be plausible, but is actually backwards. In order to protect the battery, the vehicle will always try to maximize the amount of regen subject to a dynamically determined safe maximum, and if that safe maximum is less than the demand for braking force, it will make up the deficit using the friction brakes.
This has been an issue that is known by some that when having bad brakes that need to be changed will cause overcharging over time. Once the pads/rotors are replaced back to stock specs, the ICE will not have to assist with braking as much as it did with the bad brakes.
'Known' might be a strong word. Mr. F has explained why the claim is of the kind that calls for, well, extraordinary evidence.
Not if you are trying to explain issues with lithium batteries and want to blame the user for having 'worn' brakes.
Chapman you left out the rest I said "known by some" NOT "this is a known thing". Forget I said anything about brakes and regen...
It's interesting but I wonder how that would really work does the car computers know that your brake pistons are traveling a further distance because the padware is getting up there or how would that manifest itself it's certainly interesting process to look at
Did the rear pads and rotors today. The old pads still had some life left. The rotors also looked good still. Since I did the front brakes first, I can tell the difference in braking with the rear replaced now and I do NOT care what anyone says, having fresh pads does reduce regen from charging the HV battery. Took it for a test drive on a known road where I know how the system will react and boom!!!! No charging the HV battery to one bar below full, just good old fashioned braking. Next step with the brake system is brake fluid flush and replacement.
Because I got pads with lifetime warranty. I can just take them off when needed and walk into any Autozone and get new ones for free. No lifetime warranty with Brembo and no location near me and I would have to come out of pocket to get new ones.
