So, I have Stoptech rotors and brakes, and it squeals when (a) it's warm after a few minutes of driving and (2) only when I initiate braking softly to slow down, but disappears after braking firmly to stop. Brake pads have about 80% left on them.
View 4 RepliesJust fired up my 2002 SC430 (115k miles) for the first time this year, so it's stood for over six months. Connected fresh battery, checked all fluid levels etc. Runs fine and purrs like a kitty BUT I'm getting a loud intermittent squeal (like you might get with a sticky pump or a slipping belt). Almost like a loud "meow" in duration & tone. So loud it can be heard from 20' away. Sometimes once per minute or two, sometime several times in a row then silence for a few minutes.
This is from the area where the Brake Fluid Reservoir is (on Right Hand Drive SC430 this is right by the Windscreen on the left hand side of the engine bay as you look at it from the front of the car (may be reversed on Left Hand drive models). Directly in front of the Steering Wheel.
(ABS) check light is on. Also "VSC" & "VSC off" check lights on (probably related to ABS being in check and VSC button does nothing to clear those lights). Also getting the buzzer alarm from the dash. Pumping the brake pedal and driving the car forward/back 10' several times on the driveway doesn't clear this.
Now, this may be that the Brake Pads have bound to the Discs (Rotors to you left-pondians). I may need to pop the wheels off and free up the Pads in that case.
I have a slight squeal from the left rear brake when in reverse. Doesn't do it all time and never when roads are wet. I disassembled the caliper and all looks good. I replaced the pads about a year ago and the noise just recently started, so its hard to blame that. I did not use the brake anti-noise lube......but I never have.
View 2 RepliesI replaced my brake pads and rotors and now the driver's side brake has a loud pitched squeal. It doesn't squeal all the time and if I let up on the brakes and apply them it goes away.
I think maybe one piston is hung up.
How do you free up a stuck piston in the caliper piston?
Or could there be another reason for the squeal.
I installed Callahan slotted rotors and ceramic pads on all 4-wheels.
When starting your SC on let's say a day where the temperature is 35 - 55 degrees, what is your initial idle RPM?
Next, how long does it take to settle down to a lower RPM and what is lower RPM when the car is still in Park?
Lastly, can tapping the gas pedal after initial start-up bring the idle RPM down while the car is in Park?
My '06 SC has about 72k miles and I've notice of late after starting it, it initially idles at about 1,200 RPM and tends to stay there until after driving and warmed up and then goes down. It used to start up at 1,200 RPM and after a very brief period of time would settle at 1,000 or 800 RPM, I can't recall exactly. My question is, is this normal related to the life of the engine, or do I have a sensor or other type of issue that can be addressed.
View 12 RepliesI get a small "squeal" from the engine usually only when it's cold out, and have narrowed it down to the water pump pulley (2nd pulley down from the top). I put a drop or two of WD-40 on the "rod" that runs through the pulley and it stops. I know not to put anything on the belt to avoid contamination but it seems to me that it's the metal bolt that keeps the pulley in place. I stopped by an O'Reilly and had the tech have a look because I was going to try a more viscous grease. He thinks that it's either the pump is starting to fail or that the pulley could have moved out of place. He said I should remove the belt and tug on the pulley.
If it moves then it's loose and needs to be lubed and tightened. If it doesn't then it's a water pump replacement. What do you all think? I don't want to drop a ton of money as it truly only squeals when it's cold, and unfortunately I'm thinking Chicago's gonna have a cold one this year even though after the engine heats up it's goes away. If you have a guess to the problem, what do you think replacement will run me. I'm only at 30,000 miles, and has been garaged until recently so I don't think it's a belt change or pump failure yet.
I just purchased a LS 460 2007, 64k miles. The brake when apply squeal, but not all the time when the break is applied. 5 times out of 10 times when you apply the break when driving the car for more than 20 minutes it start to squeal. It does not squeal when you first drive in the morning, but after driving more than 20 minutes, when you apply the brake - it will squeal on and off during various application of the break. Does the LS460 have brake indicator that would squeal all the time when you need new break? I am not sure what the sign that LS460 would need new break and rotor.....
View 4 RepliesSo I purchased my 2015 Lexus IS 350 AWD F-Sport back in October and experienced the following issues:
1. Brake squeal
- seems to occur when reversing out of a parking spot for example, so annoying and extremely loud, makes it sound like my brakes need changing
2. Bluetooth Radio
- there are times where my phone connects to the radio, plays music off my iPhone but then it sounds like the singer is slowly dying i.e.: the type of sound you used to hear when a walkman's batteries would be dying and needed changing. Happens sporadically
3. Gas tank lid on side of car won't close fully
- this happened just this week. I couldn't close my gas lid, no matter what I did. I managed to get it closed today after starting my car, wonder if its related at all to power/engine being on etc?
4. Buzzing in gas pedal resonates through foot
- this one is still driving me insane. Drive my car for 10-15 minutes on the highway and your foot feels like pins/needles from the buzzing sensation from the gas pedal.
Experienced a brake squeal noise on their car when they first drive it? After a while it seems to go away? The sound is similar to a low brake indicator squeal but not as loud. I hear it on my drivers front wheel.
View 8 RepliesHow to fix the low speed brake squeal on my GS. I have an o6 with about 80K on it. Have had it for four years and never winter driven. I am debating trading it off on an AWD GS or putting it into full time service as my year round driver.
I haven't driven a rear wheel drive car in the winter for 20 years. Everything else I have is AWD of 4x4. Here in Alberta we get some serious snow and ice. I have Nokian WR2 tires on it year round because you can get snow in the mountains even in July. I tried mine on the driveway after a good snow fall and even on Winter ESB and with good tires, it does not seem to have great traction.
Have any of you used your GS430s in regular winter driving, heavy snow and ice. How to get it to perform its best in deep snow or very slippery roads?
When I press and hold the brake and lightly release the pressure. The brakes would make this loud squeal. This happens when the car on or off. Just found out today that if I have to stop really suddenly, it makes the same noise. I have an rx450h w 42k miles. Any thought?
View 11 RepliesI bought Akebono cermaic pads for my GS 350 AWD which I thought were high quality good fitment pads as they even advertise them on tirerack. Now I am not really impressed. After about a month every time I pull out of my garage in the morning they click and squeal (squeak).
The scenario: After I come home from work at night I pull into my driveway and park in the garage. The pads are already seated in the forward position from driveing forward and parking. Then in the morning I go and back up in reverse to pull out, I tap the brakes to stop and shift into drive to pull forward; at the moment I depress the break pedal the two front rotors simultaneously click and sometimes squeal. Sometimes when I get in my car at the transit center in front of everyone this happens.
Is there a shim kit or something I can add to the brake pads to sit in between the pads and rotors to get them to stop moving. I know that there not moving a lot but whatever play they have is causing me brake pad buyers remorse.
I went with these Akebono ceramic because they dust much less then stock semi-metallic pads. Becuase I had them on my Audi and they didnt dust nearly as much as the stock set. But once and while they too would click in this situation but nearly as much as now in my Lex.
I bought the 2013 GS 350 F-sport thinking it would be a long lasting reliable car.... I've had brake squeal since day one. My car now has 45k miles on it, all miles driven with the insanely loud brake squeal. It's been to the dealership many times but they've change the brake pads only once and refused to resurface or swap the rotors. After I called Lexus corporate and filled a case, I finally got the managers attention. (1800-25lexus for those in need)
The manager tells me that the brake squeal can be caused by the drivers driving pattern. He basically said that if you don't drive hard enough or maybe even drive too hard, the rotors will glaze over and you will get squeal. -so let me get this right, I have to drive a certain way all the time so I don't get brake squeal? - Long story short, he asked me to come in again so he can see the squeal himself.
Aside from the brake squeal..
-My front and rear passenger side shocks blew out and were replaced at 20k miles.
-I've had a rattle in my passenger side dash since 10k miles that the dealer refuses to fix. They say trying to fix it will cause more rattle.
-My back up camera is now pointing too low. Every time I go in for a fix it just ends up happening again after the fix.
-My rear view mirror is loose.
I can deal with the small things but that damn brake squeal is so loud that it actually pierces my ears when I brake next to a car with my windows down.. Brake squeal has now started on my sisters 2014 is350 f-sport as well. How I can fix the brake squeal so I can sell the car?
@ 45k miles.
1) Loud brake squeal left front on very light pressure. Pads have 75% left.
2) Vibrating/thumping noise up front above 80mph. Does not sound mechanical and not felt through the wheel at all. Seems like a loose piece of trim flapping. Wheel well liners and plastic pan under car seem tight. And no, driving under 80 is not an option.
VAG quality FTW!
Reading thru all the squealing noise posts made me want to ask about mine. I have started to notice a high pitched squeal/squeak that occurs while sitting stopped with your foot on the brake...then let off the brake and take off and get this momentary squeak that doesn't continue (at least I can't hear it). It seems to stop once you get going again.
Seems to be coming from the passenger side front. I think I started noticing this after my most recent tire rotation and balance. What the brake wear indicator sounds like or if I will get an icon on the mfi when the brakes need service. The brakes do not squeal when in use. I currently have 27000 miles.
My brake light and ABS lights appeared today on my '02 SC430. What this might mean and the solution?
View 4 RepliesIs 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?
View 11 Replies2002 SC430, 150,950 miles.
Had new front brake pads, re-surfaced rotors, new windshield fluid level sensor installed, 4 x wheels balanced and rotated on 8/11 at Lexus Dealer. Picked it up 8/13, drove 30 miles and it sat 8/14-8/16. Drove to work on 8/17, and on the 18 mile freeway trip home yesterday, the Brake and ABS dash lights came on as I was making a gradual left turn with damp roads.
Thought nothing of it initially, thought my knee had hit the e-brake as mine is very touchy and as long as you pull the release, the light goes away. Not this time. The Brake and ABS lights were on for 4 minutes, then eventually the VSC and VSC OFF dash lights also came on. Steering became difficult, checked brake fluid (ok), checked power steering fluid (ok). No leaks underneath, all fluid levels were just checked on 8/11 and were fine/topped off.
Parked it, set up an appointment and just dropped it off this AM. I've read brake booster, speed sensor, alternator, skid control unit .
I am hoping it's just the alternator, which makes sense with the difficult steering and the lights going on one by one. If the alternator isn't outputting enough volts, those lights will trip. I've had all O2 sensors recently replaced, other standard preventative maintenance done (timing belt, thermo, etc). I'm just hoping it's something manageable and not something that makes me wonder if the repair is worth it (vs the value of the car)...
There are no CEL lights, just the above (no codes to my knowledge).
My issue is that when I tap on the brake light it doesn't come on. I need to press on it hard for the light to come on. How exactly do you adjust the brake light switch sensitivity?
View 1 RepliesWhat is the process for flushing the brake fluid for a 2007 or any other year from the Lexus Service Manual for our cars? I have read what I believe is the correct process on various threads but would prefer to read the service manual directly.
