I only get a brake warning light when it is below 40F and I take a turn. It then goes off by itself. I suspect the brake fluid level sensor may be going off. But when I looked, I didn't see a 'float' sensor.
So today the cold soaked car showed midway between Max-Min. Ok, top it off and drove to parts store only find it was just over Min. Lesson learned, check AFTER driving.
What are the odds of the brake fluid being low, and not being indicative of a leak, in my new-to-me 2012 prius two? It's at the "low" line. The dealer said they put all new brakes on it before they sold it to me as pre-owned & certified, so the low fluid level shouldn't be low because of related brake component wear.
View 4 RepliesHot or cold? I just changed the fluid so should I adjust the level when cold? And with the pump off I assume?
View 1 Repliesseem to be losing brake fluid from the area of the ABS system and it dripping down on the brake lines underneath. Noticed this when draining excess oil from the engine (dealers!!!!). I'm thinking this has been leaking a long time. I have the worst luck finding a reputable mechanic anymore and if I can't trust a dealer...
View 9 RepliesThe brake light came on randomly yesterday, flashing foe about 5 seconds, then shut off. Hasn't come on since, but I looked at the brake fluid resovior and the level is about .5cm (.2inches) below the "min" marker.
Can I just open the resovior, pour in the fluid, recap it and go? I remember hearing from someone that if you open the resovior cap at any time, air rushes in and you must bleed the entire system before you can drive again
80km on my accent, the brake pedal was getting softer and brake fluid was a bit low as normal due to brake pads were worn up over time. Brake pads were never changed. I thought changing the pads would change the softness of the brake pedal. I changed the brake pads, left and right, the brake fluid in the reservoir went up as normal but I drove around but the softness of the brake pedal did not change. I still had a little less than half size on the old pads. I need to press the pedal a bit much to feel the brakes. I am wondering maybe the brake pedal was always like that when I bought the car.
View 4 Replies Just bought a 2007 supercab with the 5.4 in nice shape, but have an intermittent brake light on the dash. (No ABS, just the brake light.) Our mech. diagnosed a bad Brake Fluid Level switch. I can get a new sensor. I'd like to try and replace this myself and save a lot of money if it's not too difficult.
I'm looking for some clear step-by-step directions on doing this, and have a couple of questions:
Do I need to disconnect the battery first?
Do I need to empty the brake fluid reservoir? (Looks like the sensor is in the bottom of the reservoir, if I take it out without draining res, will I have a mess?)
When looking up the sensor online, I also saw the plug/connector for sale, should I replace that as well?
About a week after my wreck I got the Parking brake light and the message brake fluid level low. The fluid level is fine and I read some other threads where people said the vacuum system was connected somehow. I knew the ESOF didn't work so I replaced the broken line and nothing changed, except the ESOF works now.
Anyway I can't for the life of me find a replacement sensor, part number or anything.
So my 2007 Accent/Hatchback started having this weird issue the other day.
My Parking Brake/Low Brake fluid Level Warning Light will coming on while driving and then all the gauges drop down. The light goes off and the gauges come right back up. All this happens within 2-4 seconds maybe. And usual happens maybe once every 6-7 times I drive it so not all the time.
I am driving, not braking so even more confused.
I started to feel the brakes get spongy. So I pulled the master cylinder forward and turned the 7mm about a half turn. Also noticed the brake fluid level low. I topped it off. Drove down a steep hill....red dash brake light comes on.....plow truck stopped at the base of hill with on coming car. Used emergency brake.
The down side is that I don't have a dry area to pump and check where the leak is. The up side is I have a 2nd car to drive (yaris).....the truck only has 45k miles on it. Where is that area that is prone to leakage on these trucks....... 2004 heritage 4.2 v6 with stick shift.... only 45k miles ....
I am going to have to change my brake pads (I am probably going to do the rear shoes as well). I was wondering if I should get my Toyota dealer to change the fluid as well. I have 116,000 miles on her. Lots of highway driving, and this is only the first replacement set, these pads last forever. The fluid has never been changed before.
View 6 RepliesYesterday the brake warning light came on in my 13 350. I checked, and the fluid level in the master cylinder was at the "min" line. I don't think I've ever had to had brake fluid in any car before. Seems to be Ok today, but I was wondering if other folks have had this happen? Of course if it happens again I'll have to check the brake system. Just wanted to check.
View 8 RepliesI checked the coolant level on the reservoir and it was low.
I decided to add coolant by removing the radiator pressure cap, however, the coolant fluid is full under this cap.
So my question is where should I add coolant? through this cap or the reservoir?
Noticed that the windshield washer fluid level is ALWAYS low, needing significant amount to refill, even when not used? I'm not talking weeks or months, so that evaporation could be the cause, but rather DAYS. No evidence of leaks under vehicle, either. What could do this?
View 18 RepliesChanging my oil today, been awhile since I had the hood open for an inspection a year maybe about 5 - 6K miles
It's been about 2 years since the prior owner had it in for a service, I recall they had it in right before we purchased it in August 2008
I live in Miami Beach where it's HOT
I noticed the inverter coolant level is no longer at full It's hard to see where it's at, actually
It's not below low, and it seems to be at least up to the bottom of the double seam that wraps around the tank, but I can't see where it levels off behind the seam
Should I be concerned enough to take it in to the dealer and pay them to hunt around until they find a small leak, or is it normal to lose a small amount of coolant over the course of a couple years
Should I just buy their high priced Toyota Super Long Life Coolant and top off the extra 1/8-1/4" or so until it's at FULL?
Any information about checking the fluid levels and changing the fluid on 2011 Prius transmission and differential?
View 3 RepliesIn the past few weeks I have seen an intermittent "Level Error-Workshop". However every suspension function has worked perfectly, and no height was lost even while sitting at the airport for a week.
How to track down the leak. I can see a tank pressure of about 13 PSI. Is that about right. I did a raise / lower while VCDS was connected and there was a pressure drop to about 11.7 PSI but no level error. What is the correct range of tank pressure settings?

I have a 2001 Grand Prix SE 3.1 that the brake pedal goes to the floor. I did notice the fluid was low , filled it up. I do not think it sucked air, although I can not be sure of that. As you can imagine, it is a beater so don't want to stick a ton of money in it. I had someone look at it that said he thought it was a "sensor" that would cost over 500 bucks. I don't know of any brake sensors at all. If there is, do they cost that much? If not would this be a master cylinder.
View 5 RepliesTopped off my brake fluid 6 months ago. Last week my brake light came on. I checked and I only had half the fluid left so I topped it off again. Today I went out and there was some kind of oil near my rear tires and my light came on again, needs more brake fluid.
View 6 Replies2001 F-150. I've got a leak around the warning switch and can't seem to find info about replacement. Is the switch and switch retainer screwed into the reservoir or is the outer ring screwed into reservoir and more of a compression type fitting that holds switch in place? Also, after removing and repairing will bleeding be necessary? Looks like everything I'm taking apart is above fluid level after I siphon enough fluid from reservoir to replace fitting.
View 2 RepliesI recently noticed that my brake fluid was leaking in my 2003 Hyundai Elantra and upon further inspection I found the leak was coming from a part near the master cylinder. I looked online and couldn't figure out if this part was part of the master cylinder or brake line or a part all on its own. I tried tightening it but It still leaks some. I read a similar post online and that it could just be that the washer needs replaced but I just wanted to check on here to see what the part is called and if I should just replace the whole thing. I included photos as well.
