Suburban :: Excessive Dust On Rear Brakes - Light Squeaking Noise When Tires Rotate
Nov 15, 2012
So my saga continues with my rear brakes on my 99 Suburban - had a glazing problem that was eventually discovered, glaze knocked off old pads and then glaze came back again. So we replaced the rear drums and pads. A month and a half later I get an irritating squeaking noise.
Noise - when the tires are rotating they make a light squeaking noise, a rotating/pulsing squeak; when the brakes are applied they make a lower pitch squeak and if I apply just the right pressure on the brakes I can get the noise to go away (while also giving it gas to keep moving).
Last night I inspected the rear brakes and found an excessive amount of dust/grime on the pads. The drums we fairly clean. The pads had a heavy layer of rust/grime on them. When I ran my finger over them it left no mark on the pad because it was so heavy, but my finger had this sooty grime on it. The rust covered about a 1/3 to 1/2 of the pads (each pad had a different amount of coverage).
Everything is brand new and I'm not sure what is causing all the dust coverage.

Just bought a 2001 v10 ford excursion limited with 127xxx miles. I have a few questions.
1. I can't get the front tires to rotate while parked and stepping on the brakes. I thought it was caused by the 35 inch BFG goodrich all terrian tires and a lift kit i dont know how tall but apparently i'm just a sucker. From the searches i did, i think the problem is that either the power steering or brakes doesn't have sufficient pressure to power both at the same time. what is the fix to this?
2. I found metal shaving in the rear differential. For lack of picture, the best i can describe it is that it looks like shaving off an ice block. Also, the fluid is gray and consistency of sludge. I searched and some said the shaving is normal and others said fix now. Which is it? I assume that the rear differential fluid needs to be changed.

I have a new car now, 2004 Grand Prix GTP Comp G, got it at 88k and it now has 167k. Nearly no problems other than routine maintenance, but here I am with an issue I can't seem to figure out.
A few weeks ago, I blew a tire on the highway, ended up getting 2 new tires put on the front and moved the fronts to the back. Tires were then rebalanced and the alignment straightened out.
The guys at the shop said the front tie end rod needed replaced, but I'm pretty sure they were trying to make extra money off a new customer because my bill was going from tires/alignment to tires/alignment, bearings, tie end rods, and speed sensors.
Now, on to my issue. When I'm driving on the interstate, I notice a humming sound that seems to come from the front passenger wheel between 68-80mph. Soon as I go over 80 or under 68, it's gone. I noticed that the noise lessened when I veered to the right, so I assumed it was the bearing.
Took the car to my usual shop, had the bearings checked, got the front driver bearing replaced under warranty. Mechanic said the passenger bearing seemed fine. Got it on the highway again today, noise is still there.

I am going to have to replace the rear dust shields and emergency brakes soon. I was wondering if we have this documented somewhere. The main question is do we need to remove the axle to replace the shield.

Feel there is excessive road noise on the highway? (not wind noise)
Seems as though it can be worse depending on the surface. Comparing the B7 to the wife's Q5 is painful. Heck, even my MKVI GTI was silent compared to this. What do you all is a good fix?
Tires? If so, what would be a good upgrade? The P Zero Neros on the GTI seemed pretty good. I'm new to car tires. Long time Jeeper. Dynamite under all carpet?

I've got a 1997 Ford Expedition 5.4 with 200,000. So my rear differential leaks a few drops of fluid every time I drive it, looks like it's coming from the pinion seal. I've just been filling it topping it off with fluid.
Anyway, yesterday I got in it and started driving, I noticed a howling noise, and when I turned my rear tires started locking up. It was like that for about 5 miles until I got home, no matter which way you turned the tires would lock up.
I went under and topped off the differential with fluid again, and I pushed my parking brake in and released it. Got back in the truck and drove, and it was fine. What happened? I'm just worried it will happen again if I don't look more into it.

So i need to rotate my tires and i want to know if there a special way to rotate them and if i need to reset the TPM system so the computer know where each tire is?

Car is a 2000 Corolla CE with 4-spd auto. Is it possible to rotate one side of the front tire while the car is jacked up? How about if it is in neutral with the parking brake on?

What is the proper sequence to rotate the stock wheels/tires? Is it front to back only on the same side or does it need to be crossed front to back?

I just had my 10k service and noticed my two front tires still had a significant amount of brake dust and the rear tires did not. I always have more brake dust on the front than the rear and was the case when I dropped the car off. The service guy said they rotated from front to back but that didn't happen. I was under the impression they moved front to back and vice versa. What is the standard rotation for tires at the prescribed service intervals?

I have a 06' Ranger 2WD with General Grabber tires that have about 30,000 miles on them and still show significant tread remaining.
Within the last 2 months, I have experienced excessive tire noise - like I am driving a Humvee or something. Also, when I turned right or left the tires would make even MORE noise - it seemed to be coming from the right front tire mostly. 2 weeks ago I had the tires rotated and the sound seems to have reduced while turning but I still have the howling Humvee noise while driving down the road. There is no vibration coming from the wheel, so I don't think it's a balancing issue. Could it be the bearings?
I also checked the PSI all around and one tire does have a slow leak but I try to keep to topped off.

I have a new 2012 Chevy Cruze with 10,000 miles on it. Chevy has issued service bulletins citing a problem that they can't seem to diagnose or repair (yet) and my car has the problem. They tell me their engineers are working on it. After the car is a little warm, when I apply the break there is a loud squeaking or whirring noise which pulsates at the speed of the tires (in other words, as I slow down, the intervals between each sound gets longer and longer). I suspect it is coming from the back. First they thought it was sticking calipers until they realized that I have drum brakes on the rear. It is loud enough that the only way no to hear this grating noise is to blast the radio.

When I look into the brakes on the two rear tires, I see a good bit of rust on the discs. Should I be concerned?

I've had my Accent for a year and a half and now it has about 23k miles on it. I noticed that whenever I would apply the brakes, and the lift my foot off the pedal, I would hear a squeak . . . kind of like a squeaky door. It would happen every time I would lift off the brake pedal. At first, I thought it was the pedal itself, then I rolled down the window and realized it was coming from my rear drums.
So I took the rear drums off which was a PITA to get them off, and used some brake cleaner and white lithium grease on the backing plates of the shoes and on the springs, and the squeak is gone!
I suspect this is probably an issue with drums since it's a relatively closed system and brake dust tends to accumulate in there. Any good technique to remove the rear drums, other than using a hammer to tap it loose?
Here's a pic of the rear brakes with the drum off.

I took my car in about three months ago when brake indicator started squeaking in the rear. Shop told me that the drums, shoes and wheel cylinders needed replacing. After spending a few hundred replacing all those parts, the squeaking began. It's a kind of rhythmic squeak that starts towards the end of braking. the rate varies with the speed of the car, so it definitely seems to be coming from the brakes. I took it in not long after. They said they only heard a clicking noise, and that was because the brakes were mis-adjusted. They re-adjusted it. I drove it home. The squeaking is still there. This also happens a lot more when it's heated up so maybe that's why they didn't hear it in the first place.
I take the car back. They said the drum has been warped. They replace the drums. I take it home. Still squeaking a few days later, and I feel the brake pedal pulsating now. I take it back in. They say the issue is from the front brake rotors being warped. I get these replaced elsewhere with ceramic pads. Squeaking is still there.
I take it back in to the original shop because I'm certain it's from the rear. They look at it again and say the drums are warped, again, and that they'd never seen anything like it. They turn the drums. (and receipt says there will be no more warranty on the rear drums... what?)
Unsurprisingly, squeaking did not stop, not even the day after. I took it to a different shop. They spent all day on it and drove it around with me and their final word is that the reason for the squeaking is cheap parts. They recommended I call the original shop and ask for factory parts and offer to pay the difference for the parts.

My Sub makes a wonderful ticking noise that resembles a turn signal--it continues to tick until i apply the brakes. i have just replaced the brake switch and the noise is still there. All the lights on the vehicle are not illuminated while it is making the noise, it makes the noise while either driving or idling.

My 18 inch Conti Contacts have approximately 20,000 miles on them. The tires are not wearing evenly and have excessive wear on the outside portion of the tires. The dealer says that they spoke with VW and VW says that it is "normal" for the tires to wear this way because of the "turning radius" of the vehicle. I smell BS. I don't know much about this subject but it would seem to me that the tires should wear somewhat evenly if the vehicle is balanced and aligned properly.
