Prius (Gen 3) :: Hard Braking / Brake Rotors Become Rusty
I have never experienced what others have described as the brake delay issue, neither before nor after the ABS recall. I have even purposely driven over rough patches of road to try to duplicate.
After two days of rain, I noticed yesterday that my brake rotors were rusty. I remembered a comment from qbee42 about putting the car in neutral while braking in order to remove regenerative braking and to force friction braking to clean rusty rotors.
Yesterday I was approaching a stop light with plenty of distance and no one in front. I started braking around 45 mph with regenerative braking and then pulled the shift lever to neutral. When in neutral and with the regenerative braking removed, I felt the decrease in braking when transitioning to friction braking and I had to brake a little harder in order to have the same amount of braking as before in regenerative braking.
I can see where someone can "perceive" this as a surge forward but I only interpreted this as a decrease in braking force, as others have stated here many times.
I tried this again at the next stop light and felt the same "sensation" again and had to brake slightly harder when in neutral in order to have the same braking force. It was apparent to me that for the same brake pedal position that the friction brakes do not exert as much braking force as the same pedal position with regenerative braking.
Is this similar to what others are reporting as "brake delay" or "surge forward" issues?
Audi - A4 :: 2007 - Rusty Brake Rotors Making Horrible Noise?
Last June I took my 2001 Audi A4 off the road since I bought a more fuel efficient commuter car but I wanted to keep the Audi in the family until my oldest son started driving. That day has come and I'm making the car drivable again. I pulled the battery over the winter and kept it on a Battery Tender. I put it back in over the weekend and the car started up up and runs just fine. The only problem is that the rotors are extremely rusted and make a horrific grinding noise. Is there anything I can do to remove this rust? I assume I can just grind it off with the brake pads but that can't be good for the brakes which, if I recall correctly, are fairly new.

A Water gets into wheel hubs much easier with aftermarket wheels than OEM wheels. I have a set of BBS RS-GT wheels and this is what the rear hub looks like after about a year. Previously I noticed with OEM wheels there is just a little surface rust. Hopefully I won't need to remove in the future as it looks welded.

I noticed the front brake pads were touching the rotors when I was painting the brake calipers. I had my e-brake engaged and in park. I'm assuming the e-brake only brakes the rear wheels because the front rotors were still movable. Although the car still rides fine but I'm not sure if this is normal.

I have a 2014 Supercab Ecoboost F150, which has 37k KM on it (23k miles). I work at sea for 4 weeks on / 4 weeks off so the truck sits a fair bit. I had it in the dealer for scheduled servicing and they noticed the inside pads on both front brakes were wearing significantly more than the outside (4mm vs 7mm). The lube guy at the time had suggested sticking calipers and that they'd be warranty.
A few days later I brought the truck back in to have the brakes looked at and an unrelated warranty item done. They looked and said the calipers aren't sticking and the rotors are grooved and rusted, particularly the inside surface. They wanted to put new pads on and turn the rotors for 400 bucks.
I had a hard time believing it wasn't the calipers, and I was having a hard time getting a good explanation from the service writer of what was going on. So I took the truck back and pulled the pass side tire off in the driveway to take a good look.
As far as I can tell, the calipers are free. The slide pins are nicely lubed and are free, and the pads are free to move in the anti-rattle clips. I squeezed the piston back with a set of C clamps and it seemed to be good. Also, the pads are wearing more or less evenly (not tapered or anything), just the inside is worn significantly more than the outside.
So, rotors wearing out in 23k miles? They aren't really warped, just heavily grooved. My theory at this point is that the weeks the truck spends sitting allows too much corrosion to build up on the rotor, which is getting caught up and wearing down the pads and rotor. Maybe the outside of the rotor isn't nearly as bad because it gets hosed down and washed more frequently?
Inside rotor surface
Outside rotor surface
Inside pad surface.
I still have 7 months of bumper to bumper warranty. Ford says the only cover brakes if the damage is caused by a caliper, so I think I'm out of luck on that front.
Ford Excursion :: Rotors Rubbing On Caliper Bracket - Brake Rotors Too Thick?
I replaced my warped front brake rotors a couple thousand miles ago and all was fine but when I went to swap over to my snow tires, I can see that the outer part of the rotor has been rubbing on the caliper bracket. This is happening on both front rotors. Could my new rotors be too thick or something?

I'm having a hard time trying to remove one of my rear brake rotors.
I thought these simply pull straight out and off, but mine might be rusted in place. I soaked the front facing area around the axle with Kroil and then tried jolting it out by tapping it with a rubber mallet. No success
What's the trick?

View 11 RepliesLexus GX 2010+ :: Parking Brake Stuck (Remain Applied) After Washing
The closest car wash is less than two miles from our home and we often bring the GX home directly from the car wash and park it in the garage. We've noticed that the parking brake remains applied when we start the GX the next morning, even though the foot pedal releases. Presumably, the parking brake components were wet from the car wash and enough rust/corrosion forms overnight so that the springs to release the brake can't overcome the 'stiction'.
The GX "squats and grunts" when we put it in gear, but doesn't move. Shifting into reverse solves the problem ... there's a loud 'pop' from the rear of the vehicle as the brake releases, the GX starts to move, but in reverse, which we quickly stop with the service brake, then we shift into forward and drive off ... did I mention that we back into our garage?
I may already have confessed that we are heavy parking brake users ... every time we park the vehicle, even if just temporarily while we step out of the vehicle to get the mail, etc. We use the parking brake so much that the cable stretches and every year our dealership has to re-tension.

Ok, so I have a brand new 2011 F150 SCrew EB direct from the factory. It's about a week or so old and I have almost 700 miles on it. It is garaged all the time while at home...
So I was looking under the front end just checking things out...getting to "know" my new truck (which by the way I love) and everything looks new and great underneath...nice new painted surfaces...metal etc until I see...the knuckles behind each of the front wheels are starting to rust. I'm assuming these are cast iron but why would they not paint these?!
I mean, everything else is painted and looks great but then you see the rusting knuckles underneath?? AM I missing something here...is this normal? For all of you who own the same truck, have you seen the same thing?
Golf V R32 :: Brake Noise Might Be Grooves On Brake Rotors
Just thought I'd ask, I was at the dealer last week and while there asked them to take a look at my brakes because they were making a slight screeching sound but only when first applied when speed was slow.
They said it all looked good but that the sound I was hearing was from grooves that had been etched into the driver's side front rotor. I find it hard to believe that my rotor would have grooves in it after only 21k miles, considering I don't track it or drive it aggressively that would have caused that.
Lexus SC430 :: Oil Leak / Drippings On Driveway
I have what I thought was an oil leak as I noticed some oil drippings in the garage virtually everyday. The last time I had the oil changed, I asked the Tech to take a look and see if he could tell where the drip was coming from. He told me he saw no evidence of a leak, however, there continues to be oil appearing on the garage floor.
Last week I took the car to the Lexus dealership in Smyrna, GA for some brake work and an alignment, and told them about the "leak" and asked them to take a look for me to see what is going on. They told me they found no evidence of a leak.
Fact is, oil is coming out of the car, slowly, but surely and two times I was told by those that had the car lifted that they can find no evidence. I assumed the dealership would find it, but no. What is going on?
Ford F-150 (2004-2008) :: Rear Wheel Wells Rusty - Permanent Repair?
have an 04 f150 that is starting to show some rust in the rear wheel wells. Right now there is just a bit of rust where the painted panel is seamed to the inner panel around the arch, but I can see small spots where the paint is starting to bubble about an inch out on the outside of the panel. I want to keep this thing looking nice for a few more years; what should I do?
I'm a very good welder, can hold my own when turning wrenches, have done lots of metal fabrication as well as painting with a cup gun, but I have very little autobody experience.
I am thinking there is rust between the inner and outer panels and that removing the surface rust and repainting would be a very temporary repair, correct? Could I cover it up with some sort of wheel well liner? If so, how to I slow the existing rust? Is there any sort of partial preformed steel panel/well that allow you to cut off the rusty stuff and weld new stuff on? I'm a little leary of the last thought- I could do the fabbing, but not sure how I'd do getting it back to 'smooth'
