Lexus SC430 :: Chirping Sound As Slowed Down To A Stop - Brake Pad Wear
Nov 4, 2012
I have a 2002 sc430 with 120000 miles, great car no problems just maintenance. For the last couple of days I heard a chirping sound as I slowed down to a stop. The only thing I could think was the brakes, but I just changed the front and rear pads March 2011. So today I looked at the front brakes and saw the pads at about 50% and everything else looked good. Then went to the rear and saw something I thought was odd...take a look at the picture.... The last time I changed the pads I don't recall having this problem. See the red arrow, one of the pads is worn almost completely down and the circle shows a lip on both pads??? I checked the caliper pistons and they work fine, the pin that hold the pads is not bent and the clips are fine.

After replacing several front end suspension parts I noticed an issue with the brakes. The car stops fine and in a straight line but right before the car comes to a complete stop the brake pedal drops about 1/2inch and if I am not holding the wheel, I see it move to the right ever so slightly. It does it every time and I am thinking that a component was either damaged or is not installed correctly.

I have a 2006 SC 430 with 20,000 miles on it The (run flat) tires are wearing on the inside and the dealer says that they need replacing The local tire shop agrees, and will sell the tires to me for less, and also throw in an alignment He says that alignment is the reason for the uneven wear But the dealer says that the wheel on my 2006 SC 430 cannot be aligned, and that the new ones will probably wear the same way

There's been a recent annoyance that's appeared in my '03 SC 430 with 32K miles. I've noticed over the last 3 months that whenever I have the A/C turned on, after a few minutes, a soft chirping sound appears. It sounds very much like a cricket chirp to be exact, kind of high pitched, but continuous. It's even loud enough to hear over my music.
I realized that it came from the A/C because it was gone whenever I turned the A/C off. I initially thought it might be from the belts for the A/C compressor, but I couldn't hear anything from the under the hood with the A/C turned on. I'm thinking it might be something to do with how the coolant flows in the lines, but can't be sure.
I'll probably have it looked at during my next oil change.

Super annoying problem I can't solve.
Front brakes have a constant chirping sound that goes away when brakes are applied.
New front brakes were installed in November, OEM rotors and pads.
They were quiet as a mouse, until i installed a new set of struts and springs along with 10mm front spacers.
(Yes I am using extended lug bolts).
I took the fronts apart this weekend and lubed the hell out of them, still squeaking.
My next thought is to use some of that CRC disc brake quiet red goo stuff, but I'd rather not use that if i don't have to.

I am looking at both the ES350 and the ES300h. After driving both, I am not sure I can get used to the regenerative braking sound from the 300h when coming to a stop. How have other 300h owners reconciled the noise?

My 2014 TDI SEL has just recently begun making a weird noise..
At around 48-60 MPH, a very low frequency hum begins and it persists until the car has slowed almost to a stop. It is not related to road speed or engine RPM.
It is getting louder and more noticeable every day. I took the car to the local dealer and they could not hear it. I'm wondering if it is an electronically controlled fan or pump or part of the stability or antilock systems.

I am getting a strange chirping sound from the engine (during idle) on my 7 month old RX350..Is this pretty common ... experienced a strange howling engine sound when you accelerate the car( E.g. when you are going at 30 mph and want to speed to 60 mph), I can hear this when I turn off all the noise (radio) and drive on a quiet street...

2008 lexus es350 -- chirping noise from serpentine belt area. Chirping starts after a bit of driving. Got belt replaced, mechanic says it is water pump (as he says he saw marking and could be a prior leak), but I don't want to do this trial and error.
I got belt replaced by the mechanic who said wold fix the problem but did not. Should I replace water pump as it is expense on es350 and only to have chirping noise not fixed as it could be something else like alignment or idler pulley etc.

I have a 2000 Mercury Cougar with about 145k miles.
Today I was driving and when I slowed down to come to a stop it acted as if it wanted to cut off by sputtering. As I got down to about 5-10mph the engine shut off (the radio and everything else was still running) I noticed that as I was slowing down right before it shut off, the RPM was going very low, almost down to zero.
I do have check engine, and low coolant level lights on.For the check engine there are a few codes.1. Something with the catalytic convertor2. 02 Sensors3. Transmission slippage4. I think there was something else but I forgot.
I do need new motor mounts. The oil light comes only when I am idle and after driving for a good 5-10min. I changed my oil about a month and a half ago though.The only time there is issues is upon stopping. Driving and acceleration is fine.

I have noticed an oil burning smell when i come to a stop. Its been getting worse. I just replaced my valve cover gaskets. With new spark plugs also. Any way after I completed the job, I let the car run for a few minutes and seemed like i could still smell the burning smell. May be its just because it all needs to burn off the heat shields, but I thought I saw some oil accumulating on the bottom side of the v.v.t solenoid on the front of the valve cover. Is that a separate cover? Doesn't seem to be a gasket there. Do these v.v.t covers leak a lot?

As I have experienced hesitation on acceleration from a stop, I found a TSB # L-SB-0154-10, that addresses this condition for the 2010 SC430. It was issued in 12/1/2010. I am not sure if it would apply to any other years. The TSB entails re-flashing he PCM with updated software.

I have a 2008 Prius. Had to do an 'emergency' stop. Put my foot on the brake pedal REAL hard and the car slowed way down, but not down enough. Munched the front end. Now remembering back, I didn't feel any 'chattering' from the ABS brakes. It seems like I got regen braking but never switched to the hydraulic brakes. Is that possible? Did I experience a braking failure? Or do Prius just take a lot longer to stop? I did a test stop in the rental car I have now (not a Prius or hybrid), and it gives me the ABS chatter as I would expect, with a short stopping distance.

Dead battery. After recharging it, the car starts but.......
1. the seat memory buttons stop working
2. the radio that hasn't worked in 8 months since i own the car is working
when the radio wasn't working, i tried to put in new fuses and that didn't work. but a dead battery did.

Son's 2000 GMC Sierra, 200000 miles, 4.8L engine, automatic transmission and 4WD. Was driving home from a trip to the store - heard a "violent popping noise" on the passenger side and the truck simply slowed to a stop. Engine running fine, all sounds fine while idling. When we put it into any gear, I can "feel" it go into gear but the truck doesn't move forward or back. Just changed differential, transfer case, and transmission fluids about two months ago.

97 4.0 ext. As the title says the right front pads wear more than the drivers side. Have replaced calipers pads and rotors during recent overhaul. Noticed increased brake dust on wheel on rf front. Could the metering valve under master cyl be the culprit. Abs and brake lights work as normal.

I have recently had my motor mounts and transmission mount replaced.
Before the replacement, the car would shake quite noticeably when the engine was being started (maybe even shake 'violently'). I thought this was normal until I had my motor mounts and transmission mount replaced. Now when I start the engine the SC430 doesn't shake at all. The difference is profound.
Just a head's up. I'm not sure what the implications are of running with bad motor mounts for a long time, but I decided to get it done because my car would shake when idle and at stop lights.

2008 r32. First time i opened it up on the highway, noticed a weird electronic whine under the back seat as soon as we slowed down that wont go away. It changes pitch when you shift and sounds like a weird electronic sys trying to mimic an exhaust leak. Id think fuel pump, but seems louder on the left side (fuel flap on right). Since i talked her into it and i apparently caused this noise, shes gonna kick my ass if I don't fix it. Its somewhat warrantied, so toss out whatever, I am not scared to go to the dealer with 500 things i want them to look at, but i need to know if their diagnosis is correct or total crap. Ive never dealt w 4motion (its incredible) and my newest dub is also a vr6, but its a 92.

When I come to either a hard stop or apply my brakes hard while on the highway I can feel a slight shift of the seat forward (as if it is tilting forward) and then when I accelerate again I feel it rock back into place. I only weigh about 150lbs so I doubt it has to do with that. It's minimal and I think it started at around 50K miles (so, just a couple thousand miles ago).

My brake light and ABS lights appeared today on my '02 SC430. What this might mean and the solution?

Is there a write up on how to change the brake fluid or is it the typical pump, hold, then open and close the valve on the caliper from farthest to closest? Also, is it ok to use dot4 super blue fluid and do we have a vendor that sells SS Brake lines?
