Lexus GS 2006-11 :: Brake Pedal Stiffening Up While Driving
Sep 26, 2015
I just got check PCS/VSC/ECS and a ring while driving. I was coming home from work and i was about a mile away (this is at 6am) and all of sudden the dash lite up the messages in the topic and just about all the lights on. the brake pedal was stiffening up and i barley made it home. what could it be? the alternator? I haven't looked at it due to the night sky but i do have a drop leak from the cam seal that is above it. also the vehicle almost died in my driveway because my navigation screen was going on and off.

So I noticed a few months ago that a clanking noise came from the front of my GLI when I hit bumps. This noise went away if I had my foot on the brake, so enough vortex searches came up with loose caliper carrier pins.
I ordered the brake stiffening kit last month, but have yet to install it. Now just the other day, I heard this crazy noise come from my brakes entering my garage. It was like a loud 'click" when I engaged the brakes hard enough and I could repeat it many times. I know, I am silly for not getting the kit installed sooner, but I want to make sure that this 'click' is likely related to the carrier pins before I go taking the brakes apart in my garage.
I only ask because my car has 95k on it and is possibly on original suspension, so bushings and mounts might be starting to go.

I have an issue when I go to start the car after it sits for as little as 30 min.The brake pedal is stiff and its hard to start since you have to depress the brake pedal prior to starting the car .

I noticed last night that the brake pedal was hard when I tried to start the car...then it softened up after I started the car.
does this mean my booster is starting to go bad ?
it usually feels normal and soft to the tap when I press the pedal and hit the start button.

I made a scary discovery the other day, or I should say, my son did... Apparently, you can shift the lever out of park, reverse, any gear without pressing the brake pedal first! 06 GX with 77k ...

Have an 07 gs350 awd and lately the pedal feels stiff and doesn't depress all the way down at startup. Sometimes the steering wheel will go back up as if I have just stopped the car and occasionally I will get the message on the dashboard that I need to press the brake pedal at startup even though I am doing that. Dealership claims they can't duplicate problem and don't know what it could be.

How 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?

I noticed something a few weeks back, wanted to see if it's normal or a potential issue is arising. When you are driving slowly, maybe coasting to a red light and not using much braking power, I notice the pedal is pretty firm. If you push on it harder, it then "gives" and feels softer and you can more easily push it towards the floor. If you are driving faster or braking harder, it feels more normal and doesn't have the firmness when you first press the brake.
I assume this is the brake assist or some other electronic nanny at work, but wanted to verify. I have checked the brake fluid in the car, and it's certainly not low.

I bought a 2001 chevy malibu about a month and a half ago.when I test drove it,didnt notice any problems or leaks...after driving it for a 2 weeks...the brake pedal would drop to the floor while driving and then if I hit it again real quick it would be ok...this problem would happen now and then....we replaced the right front caliper thinking that it was sticking and bled all the brakes..There was air in the system..everything was fine for about two more weeks then while driving the pedal would get hard when applied and then drop again..not all the way to the floor,and it alternates that way..what are your thoughts? I don't have much money to fix this problem.

So I changed out my front brakes and rotors on my 03 camry le, and I noticed the driver side pads are more worn out than the passenger side. Also when im driving highway and coming off I notice some vibration in the brake pedal, its not all the time though. Do you think my caliper is partially sticking? I can manually push the piston on the caliper piston using a clamp.

My truck is experiencing a hard to press brake pedal. It comes and goes and does not seem to happen at any one time while driving. I know that my truck uses a vacuum pump and instantly replaced this as I figured that with the age of the truck it should be done. However even with a new vacuum pump it did nothing to correct my problem with a hard to press brake pedal. I inspected all the lines to ensure that they are holding pressure and replaced two of the three with new lines. Again it still did nothing to correct the issue. I do not have any leakage coming from the master cylinder and no hiding noise from the brake booster.

I have been having a mysterious problem with my 2007 Pontiac Torrent that apparently no one, not even GM, can diagnose. I have done great research on this problem, and although there seems to be many many folks with Stabilitrak/Traction Control message issues, none seem to be having the same problem I am having.
Problem: After driving my car about 10 minutes, the brake pedal gets progressively stiffer and the car itself is “heavier” (no other way to describe it). If I continue driving, the car will begin to make a low roaring sound, which will get louder and louder if I continue driving. The car also at this point will lose acceleration and it is very difficult to make the car accelerate (that also makes the noise louder). A couple of times (luckily I was in my garage at home after driving), the car was stopped and when I tried to reverse, the car would not move at all.
When this problem first started (about 6 months ago), the Service Stabilitrak and Service Traction Control messages would come on, but I had a part replaced and that stopped (although the car was still having the same problem) until yesterday when those messages came on again. It has been four months since the messages stopped, yet the car was still having this problem during that time.
My remedy to this problem has been to pump the brakes each time I stop (I now take the highway instead of the interstate so that I can make enough stops to do this). I can go about 10 minutes before I have to stop, pump the brakes, and continue driving. This makes the stiffness in the brakes stop and keeps the car from making the noise and having the acceleration problems. The car runs fine as long as I do this.
During this six months, I have been to two different auto mechanics AND the local GMC dealer (at least four times). The parts that have been replaced are: right rear hub bearing assembly, EGR valve, rotors resurfaced, left rear caliper repaired, brake pressure modulator valve, and electronic brake control module. The dealership says they do not know what is causing this problem, and they claim they contacted the technicians at GM and they have never heard of this problem.
I feel this is a problem in the braking system. Something is getting hot the longer I drive and causing something to lock up the wheels, but not enough to stop the car entirely unless I continue driving. What stumps me is why does pumping the brakes work, and why are no service messages or warning lights coming on?

I have a Toyota Corolla 2010 LE. When I'm driving, no matter how fast I drive, I feel a vibration sound. When I press brake pedal, it's worse than driving. I recently replaced front rotors and brake pads. I also replaced whole tires a month ago.

When I press the brake pedal, the car will stop. But if I keep pressing it while the car is stopped, the pedal wants to keep going towards the floor. I have to press hard for it to do this. I have bled the brakes. I've checked the calipers and the hoses for leaks and don't see anything. The master cylinder is topped up and I don't see any fluid underneath it. It doesn't appear to be leaking. The funny thing is, when I turn the engine off and press the pedal, the pedal comes to a stop and doesn't want to move after I pressed on it as hard as I can.

My dad drives an '06 Sonata. And he recently broke a brake line and had gotten it fixed. His current problem is that his brake pedal hasn't returned after getting the line fixed. What can he do to fix that? The pedal is really low and is spongy. And his ABS and ESC lights are also on.

I have a 2007 Sonata GLS 4cyl. Anyhow lately my brake pedal is going right to the floor. The brakes seem to work fine, but if I keep constant pressure on the pedal it will slowly go all the way to the floor. My rear rotors and pads have been changed a couple of months ago and I'm pretty sure my front brakes are good. What could be causing this? I also checked underneath the car for leaks and there doesn't seem to be anything leaking underneath.

I drive almost all the time in stop and go traffic and my knee hurts because the brake pedal is too high. My wife also noticed that the brake pedal is unusually high. Is there any adjustment I can make to lower the brake pedal?

The brake pedal felt much lower or closer to the floor than normal right after I leased this car.
when I'm driving, when I first press the brake pedal, it seems too low and somewhat vague, maybe squishy would be a better term. The stopping pressure always seems like it varies as the speed reduces and I come to a stop. If I pump the brakes once, the pedal comes up to what seems like normal to me, and the stopping also feels normal.

Just noticed this the other day, when depressing my GF's 2011 Accent's brake pedal it made a low hissing sound, it would go away when you took your foot off the pedal, you would never hear this with the radio on, but it was enough to make me think it could be a concern.
Drove the car and it didn't affect the brake permormance, but the longer this goes, I can't imagine this being a good thing.
Car is 3 years old, and has 80-20 city/hwy driving under it.

Started a few months ago didn't really bother me until now. Started when I would forget the parking brake is on and would just put the car in reverse & wouldn't move until I released the parking brake. Did it about 5-7 times and now every time I brake without the parking brake on, it squeaks & is really annoying. Is there any way to fix this or is it just gonna be complicated & expensive?

I'm getting this checked today most likely as it's been happening for months now. No issues with vibration and stopping is fine. As a matter of fact brakes are excellent. However when I'm stopped at a light or whatnot and I depress the brake pedal there's a pulsation that occurs almost every time. It's fairly constant and only happens when I'm at a stop not when I'm stopping so I know it's not a warped rotor. What it might be?
