Cadillac :: 1950 - Front Right Makes A Grinding Noise While Brakes Applied?
Sep 9, 2014
1950 cadillac - standard drums on all 4 corners.
I put new wheel cylinders on each drum, and replaced the drivers front hose, as it was clogged. The passenger side I left because it works and doesnt leak. I've cleaned all the brake surfaces, shoes and drums, and bled everything.
When I brake, and only when I brake, the front right makes a grinding noise and the car pulls to the right.
I tried tightening the star wheel today to bring the shoes inward in hopes that would equalize brake pressure up front, but when trying again today, I got that grinding sound still.
There is no scoring or gouges on the shoes, drum, and the inner and outer ball bearings seem fine - round chrome balls with no discoloration, no gouges on the spindles. Granted I don't drive this far at all, especially now that I have this grinding.
How can I really tell if its the ball bearings? It only makes the grind when I am on the brakes.

Coming to a left turn signal I was anticipating it turning red on me, and I drove into the turn lane briskly 30mph and then applied brakes as I made a u-turn. It sounded like a cross between dragging the front air dam and metal on metal brake grinding as I made the turn. Stopped immediately and did not scrap the air dam and all front end components checked out, okay. Car is driving just fine now, has only done this once.

So I have a 2003 Passat wagon. While driving down the road with no brake pressure applied the front right brake makes a squealing noise. As if the caliper doesn't release pressure....what should I do? Any hints?

Is it just me or is this an ABS thing? during a snow storm i was going about 25mph and had applied the breaks and started making a grinding noise... if it is the abs how are you suppose to work with the response time for a quicker stop.

I noticed yesterday a sound, like a grinding sound, *sometimes* as I apply the brakes to stop. I'm at 68k. The noise only happens when the brakes are applied so I suspect there is an issue with my brakes again.
Some BACKGROUND info: At around 60k (or 8 months ago roughly), the front pads were replaced after the brakes were squealing and a pulsating brake pedal when stopping. The pads were replaced by a dealer. In addition, both front/rear rotors were turned at the same time. Rear pads had 40% at the time and were not replaced.
Some weeks later the pulsation came back and I went back again and they machined them again. For this current issue I was thinking about taking the car to someplace local (not a dealer) and getting a free brake evaluation of what is going on.
I'm also concerned that all this machining the dealer did to eliminate the pulsation may have decreased the life of the rotors and perhaps they need replacement now.

I'm going to be freshening up my distributor for my 1950 Cadillac, and I think because of bad weather stripping and other leaks, when it rains heavy, moisture might be getting on the distributor. Is there something I can spray on it that will repel moisture or would just a healthy dose of dielectric grease do the trick?

Is there a safe way to remove rust from a cooling system? It's on a 1950 cadillac that's all cast iron with a copper radiator. I'm pretty certain the coolant passages in the engine are plugged up from rust. I took off the rad hoses and rinsed everything out until it ran clear, but I've done this before and the car still runs hot.

I have a 2007 Toyota Camry 4 cylinder and the ABS light comes on intermittently. Not only does the light come on, but sometimes when I apply the brakes, the brake pedal makes a grinding, vibrating sound that I can hear and feel under my foot, and feels as if the brake pedal is going to go all the way to the floorboard. If I quickly pump the brake, it stops that sound and the brake works fine.
I have taken the car to O'Rileys and Firestone and they put it on the analyzer. Two codes come up which indicate that the right front ABS was bad and/or an open circuit. I replaced the ABS sensor, but the problem described above persists. I took it back to Firestone and the same codes displayed. Firestone said it was an open circuit and that I should take it to the Toyota Dealer. I called the Dealer and they want $135 to analyze the car. They won't tell me what they will do in the analysis. I also took it to Just Brakes and they kept it for 3 days and could not or did not do much other than suggest I take it to the Dealership. I have read that the Dealership will probably say the ABS computer needs to be replaced ($1,000). I have also read that the 2007 Camry Hybrid ABS brake system has been recalled, although my Camry is NOT the hybrid.
There has had two fender benders on the left front side and the right front passenger tire hit a curb which bent the tire, but the tire has been balanced (not sure if the wheels were damaged in these minor accidents or if the wheels could be causing this?) Other thing that occurred right before the ABS light started coming on, and the brake issue, is that the air conditioner went toes up, and there were small metal fragments within the air condition housing unit. I replaced the whole A/C unit. I haven't been able to assess if one would have anything to do with the other, but it is interesting that the ABS and brake issue all started within a few days of the A/C unit being replaced.

I have a question: when physical brakes applied (at the end of the slight braking, or when speed is small, or when gasoline engine starts on parking car, or when i apply brakes on parking) i hear light "pssst" sound. It is like sound from back door stay assembly, when i open back door, or like suspension shock adsorber works. My local service bleed the brake fluid, but it doesn't work. When we bleeding rear brakes (left and right) and opens bleeding plug, that noise sounds continuously until we close bleeding plug. And there is no air in old brake fluid... Technician says, that sound is normal, but i also have Toyoyta Prius 20 and there is no noise while pressing brake pedal... I just want to ask: is that sound normal for Prius 30 or not?

I have started hearing a noise with my brakes. First thing in the morning when I back up and apply the brakes, I get a clunk or pop noise from the left front wheel. It will pop again once I move forward and hit the brakes. It only does the noise one time when I first apply the brakes in either direction. Once the brakes have been used out on the road and are warm, there is no noise when changing directions. I've had this noise in another car I used to have and it was caused by the aftermarket brake pads not being exactly large enough and there was slight pad shifting in the caliper. Being this is a new car and has the OEM pads, I would hope there would be no pad shifting or movement in the calipers.

I've got a new issue that is happening on the front end of my truck. Whenever I try turning my wheel while driving, I get this rubbing/grinding noise coming from the front of my truck. It only happens when the wheels are in motion. It seems to happen less when I'm driving at higher speeds, but I can notice it make the sound at any speed. I tried driving it slowly in an empty parking lot while turning and it's definitely making the sound every time the tires rotate.
I took it in for an alignment because this was happening every time I drove, whether it be driving straight or making a turn. Now that my alignment has been fixed, it no longer make this noise if I am driving in a straight line, so it only seems to happen when I'm turning. I had the mechanic check to see if they could reproduce the issue. The mechanic was able to hear what I hear, but when he put it on the lift at the shop, he was not able to reproduce the sound.

2008 Passat Komfort Wagon with 34,500 miles. Started to get grinding sound when I applied brakes, which diminishes as I drive. Thought it was rust, but sound is very loud and sounds just like pads are gone and digging into rotors. The brake warning light is not on.
Dealer told me rear caliper was closing unevenly and recommended service---not covered by warranty of course. When I picked-up car same noise as before. The service manager told be that the car was just washed and the rust built up in the last hour---I could believe some built-up, but the sounds made my teeth ache. When we went for a test drive the noise got quiter, but was still apparent. The SM told me this is a "normal" noise. I have had many cars with disc brakes, dating back to a 1960 Jaguar; none have made this "normal" sound.

Over the last 2 wks or so I have been hearing grinding noises out of the right rear brake. 1 day it sounds like it was metal on metal. Think is just all the road salt catching between the brake pads?

Here's my issue, after a full break job my right front brake began to grind. Curiously it wouldn't grind initially after breaking soon after start up. I could go on and slow break for quite a distance, but soon after a hard brake or just slow breaking long enough the grinding begins. I've taken the car back to Firestone three times and even after a few adjustments or cleaning the problem persist... I've starting to feel bad for Firestone and embarrassed to be holding on to this 99 Chevy. I can't continue to drive this small car that sounds like a MTA bus while braking.
But I digress... I did notice, purely by accident (or it may be a mere coincidence), a few times the ABS light came on and during those periods the grinding was less abrasive. This leads me closer to believing the issue is with the caliper.

I am in the process of replacing the front hub seals so my ESOF works again. I tested both front hubs with a mityvac and neither one of them holds any vacuum at all. All the lines are good, and the pump and solenoid seem to be working fine.
I have the driver's side apart and I have a couple of questions.
What's a good source for the vacuum seal? I've checked rockauto, riff raff, and diesel o-rings. Diesel o-rings has it, but the description says it's only for 2003+ Excursions so I didn't order it.
There is no yellow o-ring anywhere on the hub. I assume that someone forgot to put this o-ring back in and this is why I don't have ESOF? I guess what I really want to know is that there isn't some 2000-specific thing where there's no o-ring, right?
After I got the hub off, I spun it around on my workbench and it doesn't sound good at all. It makes a slight metallic grinding noise about 1/2 way around. I assume this isn't normal? AFAIK these are all original parts - but the missing o-ring means to me that someone already had it apart.
There was a lot of water intrusion and rusty colored grease but nothing was dry, the needle bearings were intact and the shaft isn't scored at all where the bearing rides. I'm hoping new seals and good cleaning and it should be good as new. And then it's off to the next side.

I have a grinding noise coming from what I believe are the front brakes. It happens when I apply the brakes and sounds like the brake pad is worn out and there's metal-on-metal contact but when I checked the pads, they are at 80-90% (rears have about the same amount left). I hear it the loudest just before coming to a full stop, from about 20 mph down to stop. I thought it was caused by rust on the brakes but after I wore off the rust, the sound is still there.

For those with a sunroof do you have the same issue as me?
On the passenger side when I apply slight pressure to the headliner, I get the following noise. In person it sounds like plastic tubes knocking around. The driver's side does not do this.

Driving in snow, braking in this car routinely handles poorly and brakes make a loud grinding sound. It sounds like the front brakes. I just had a brake job from a trusted dealer. I read the thread here on the Honda Accord that reported the same sort of brake problem. The issue is the brakes, NOT tires as that thread suggests. Braking strength is greatly impaired under these conditions. I am very apprehensive about driving in snow, and ready to trade in what is otherwise a fine car.

So, last week I got my transmission replaced and they also had to replace the CV axle because it was damaged beyond repair when the Transmission self-distructed. They drove it after all the repairs and said it was driving fine, just that it had a belt squeak.
On my way home (30 min drive) about 10 minutes in, still in the city, my brakes start making a grinding noise and sort of a thump thump thump when I brake which sounds like its coming from the passenger side front, it makes me really nervous. It doesn't sound like any brake grindy noise Ive ever heard before and it wasn't making any brake noises before it broke down. (On a side note: it also made a weird noise maybe the first 3 times I drove it after getting it back and I turned the wheel hard to back out of a parking space, that used to be when I heard the belt squeak but I haven't made it squeak since I got the car back.)
Everyone I talked to said it sounded like it needed new pads so tonight I bought new brake pads and rotors for the front and got everything taken apart. The rotors didn't look bad at all, just some light surface scratches, nothing deep, no warping I could see, and the brake pads look almost brand new. I did notice that the inside brake pad on the passenger side was missing its little metal plate that is usually between the caliper and the pad, so I went ahead and replaced all of the brake pads hoping this lost metal plate was the issue.
I also turned the rotor by hand on each side while the brake pads were off and the only difference I could notice was when turning the passenger side one it made a little more noise almost like it was loose.
I got everything put back together and drove around the neighborhood with my boyfriend in the car to listen, the grinding noise was gone and it seemed to brake really well (never got above 30 mph.) However, on my way to return the rotors to advanced auto (45-50 mph) it started making the thump thump thump noise but without the grinding, still on the passenger side. I can feel it in the gas pedal and now it not only happens when I'm braking, but also any time I let my foot off the gas pedal. The only time I dont feel/hear it is when I'm accelerating.

2005 Lexus RX330. 98K miles. 2 year intermittent problem. When apply brakes the front end shimmies until car completely stopped then go again & all is well until at some future time it happens again. Dealer checked twice & private repair checked also. Nothing found. Tires re-balanced & rotated several times. Newer tires with no issues. This is an INTERMITTENT problem. The rotors have been, new pads & spring installed.
