My Gen I Prius is screeching at me with the BRAKE and ABS lights on, and I hear the electrically actuated pump pulsing as it tries to get pressure into the system. The pedal is spongy and will go all the way down, with the right amount of exerted pressure from my foot.
View 6 RepliesI noticed last week that my brake pedal seemed more spongy than usual. The next day the pedal would go down about half way to the floor before I had pressure. And then the next day the pedal would go straight to the floor. Pedal comes back up once released. I still have brakes pressure about an inch before the pedal bottoms out. Its been like this a couple days now. The vaccum pump works fine. I'm gunna try bleeding the brakes on it tomorrow.
View 5 RepliesSo I've got spongy brakes on my 2003 Prius. I've flushed the whole system twice. Replaced the hoses, pads, rotors, shoes, and drums. Still spongy. I'm not sure what to check next. No lights or codes. I'm leaning toward the master cylinder. You can pump the brakes up when they become spongy and they hold solid. If you practically stand on the brake pedal it will slowly bleed down. This tells me the fluid pressure must be escaping somewhere. I don't want to just blindly replace parts.
View 3 RepliesMy 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.
View 4 RepliesI have a question about the bleeding the brake? When I washed my E, I usually spray the wheel and the brake part. I don't know it is a good idea or not. Recently, I felt like I have to step further on the brake pedal to apply the brake.
The force is there and Brake assist is still in effect if I step fast enough. I just felt like the brake pedal is spongy. My E is on 36k right now. Do you think wash the wheel often will cause the problem to brake line?
I have confirmed that my Gf's Elantra is easy and ease to brake than mine. At the mean time, her brake fluid is darker than mine. My brake fluid is full and clear. Maybe I should not wash the wheel more often. Or maybe I get OCD too much?
I have a 2000 Silverado 1500 replaced calipers, master cylinder, and ABS Pump/Modulator. Bled all four calipers. Brake pedal spongy and has very little pressure and travels all the way to the floor. What am I missing here?
View 8 RepliesI just finished replacing pads, calipers, rotors, wheel cylinders & brake drum hardware on my truck along with flushing the brake fluid. The brakes work but the pedal goes almost to the floor. While bleeding them some air did come out as expected. But a couple times the master cylinder reservoir got very low on fluid. The workshop manual talks about bleeding the MC but are special fittings needed for that?
View 10 RepliesDrove the lady's car out on some errands today and ran into a problem on our drive home. Car was pinging really bad (low rpms in 1st and second) and car seemed as if it couldn't get out of its own way. Was driving for some time on the freeway (after a blistering 0-60 time of 20 seconds ), and noticed that the brake pedal was really spongy (felt like a mk1 when you try to brake with the car off). Found that the e-brake handle was up (negligibly up (perhaps 1mm raised)). Didn't have power brakes at all and had to use a lot of engine braking to slow the car off of the freeway.
Rear of the car smells like copper (wet pennies) and found that the brake reservoir is cracked (but fluid still at max level). Also noticed that as of late, when the car is at a stop (sometimes in gear, and sometimes in neutral) the car will rock/bump a little almost as if someone were giving it a bumper kiss with their car.
After my local brake shop changed the front rotors and brake pads on my 99 grand cherokee the brake pedal is spongy and long, almost reaching the floor. They don't know why. Apparently they had a problem with fitting the new pads. I took it to the jeep dealer and they told me the master brake cylinder was leaking and needed to be replaced. many hundreds of dollars later the brakes are still spongy and long and does not correct with repeated pumping. The dealer was also stumped and I complained that nothing changed with the new master cylinder. what might be the problem?
View 4 RepliesI have a 2008 Ranger Sport 4x4. I noticed yesterday that when I stepped on the brake pedal it felt like nothing was there until I step a little harder then it was like full brake application. The truck only has 63000 on it. Then every once in awhile it would be normal ie very light brake application and slows like it should. Then back to same issue... Any thoughts about this??
View 8 Replies2009 XRS ABS brakes .... I changed all four brake pads and flushed out most of the old brake fluid. Bled all four sides. But now while I am in idle (like waiting for a light to turn) my brake pedal is spongy and is making a hissing sound. All was good before I did this job.
View 3 RepliesI replaced all the brake pads on all 4 wheels. Pretty standard procedure. I now have a very spongy brake pedal. It stops but the pedal will be almost to the floor. I did not break any of the lines open during the procedure just used c-clamp to spread the calipers. No ABS light. Have a Snap-On power bleeder and bled the system several times with no change. Checked the power steering fluid level and inspected entire system for leaks.

I have replaced booster, master cylinder, all four callipers, and bled the brake system a number of times on my 2000 F-150 4x4. and still the pedal is wicked spongy, is there some other problem?
View 6 RepliesIve got a 2002 f250 Sd 4x4 with 93000. Im getting severe vibration from the front drivers side at highway speed. I thought it might be a warped rotor but i cant feel it in the brake pedal, when I put the brakes on. How can you tell when the hub bearing assembly is going bad? The truck doesnt pull to that side either. I can hear it, and feel it more when i'm going around highway corners. When im driving through town, I can hear a "clunk,clunk,clunk" noise coming from that side also.
View 14 Replies2005 with 110K miles. Had oil change about 2K miles ago, tires rotated about 1K miles ago. I was at a stop light when I felt a little movement in the brake pedal and the lights all came on. Brakes continued to work, but somewhat harder to push the pedal. When first applying the brakes, there was a very slight wandering of the car, which was easy to correct.
I drove the car home and turned it off. About an hour later I started it and the problem was gone. I took it to an independent garage the next day. Their scan tool found C1357 -- decrease pressure solenoid fault -- but could not go further into sub codes. They recommended that I take it to dealer.
I drove my 2005 Prius 2 hours and parked it for 5 hours. No problems on the trip down. I got back in it and it started up just fine. I was sitting in the parking lot with my foot on the brake (hadn't moved yet) and the following occurred:
The brake pedal seemed to push back on my foot
The red exclamation point illuminated
The yellow exclamation point illuminated
The ABS light illuminated
The VSC light illuminated
The red parking brake light illuminated (not shown)
All of these lights point to the skid ECU. It seems like my skid ECU is toast or something called the ABS & BA & TRAC & VSC Actuator is an issue (never heard of it but I see it connected to the skid ECU). I did a visual check of what I could and everything seemed in order. I pulled a bunch of fuses and I didn't notice any that were blown. (I didn't pull them all but will tomorrow)
After not finding anything, I drove back home. As expected, I had no regen but the bigger problem was that I had no power assist on the brakes. A few times I actually did skid and the car brakes really bad without regen or power assist. If it was raining or snowing I could definitely see a hazardous situation.
I'm kind of at a loss here. Tomorrow I'll pull the kick panel down and see if the skid ECU is getting power but I can't think of anything else that would cause this situation.
I have a 2010 Prius Hybrid and lately, on an intermittent basis, I will press the brake pedal and push the start button and the dashboard lights up as normal but when I go to put it in gear nothing happens. The last time it happened the fan was running and I couldn't turn it off. It's like the car is all set to go but all the interior controls don't function. I then shut it off and restart it and everything works.
View 1 RepliesI'm having issues with my prius that are baffling me and I was hoping some of you smart prius masters could lead me down the correct path, I traded in my dodge durango to get 2 cars, a Lexus which runs great and then a 2001 Toyota Prius, The problem im seeing everytime I drive the Prius is no matter how fast im going when I release the gas pedal to quickly i get 3 warning lights (a triangle warning, Check Engine, and a Car with an explanation mark) the car will then only take off to a max mph of about 15-20....If i pull over and restart the car the warnings go away after about 4-5 times of turning the car off and on, I plan on taking it to the dealership.
View 5 RepliesI have a 2003 Prius that I have had about 4 years. It has under 80,000 miles on it and I have the Ecrostech Scanner which I have had for about 3 years. For the time I have had the Ecrostech I have noticed times when the regenerative braking was not working when I would depress the brake pedal. I understand the regen does not work from about 7 mph and below but my system often does not work even when it is above that speed. I have not been able to force it into regen. It seems to have a mind of its own as in perhaps a faulty ecu.
View 7 RepliesMy 89 240 is a project car so I am just fixing everything up as new until it's all done.
Replaced the Brake Booster with a fully reconditioned one, a new master cylinder, full pressure bleed, new pads. Now I have fantastic brakes but they feel super spongy still . As an example, I make an emergency stop to check if they are ok and after stopping just fine , the pedal still wants to go down further. I have checked all the flexible lines for ballooning and they are ok .
I bought a 2001 Excursion Ltd 4 years ago. A previous owner put Warn Premium hubs on it, which I would have eventually done myself.
I got stuck a couple of weeks ago and tried to use my 4wd. Nothing.
A friend suggested I replace the Transfer Case Motor as it can go out if you don't use it. I got that done today but I still don't have 4wd.
I can hear the transfer case shift and see the drive shaft spinning, but the front tires don't spin.
I thought it was the PVH solenoid, but discovered the Warn locking hubs don't use the vacuum and it has been disconnected/plugged.
