Sonata NF (2006-10) :: Red Parking Brake Light Come On - Master Cylinder Level Was Low
Jan 29, 2013
So my May 2007 V6 Sonata with 143,000 km (89k miles) had the red parking brake light come on. Master cylinder level was low and there was evidence of something leaking on the driveway. Below the very back of the driver seat.
At the dealership they say I've got a leak in my brake lines. Say that the fuel lines should be replaced too since they are in the same compartment. So if one goes the other may not be far behind.
I was out of town and the car couldn't be driven safely so I was pretty much stuck there.When the dealership did the work a rusted bolt snapped near the fuel tank and they said that added an additional hour of labour to the work. In the end I wasn't charged for it. Tech said he had never seen a Sonata have the brake lines rust out like that. I got the brake and fuel lines done cause I plan on owning it for 6+ years.

Yesterday 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.

My son's 2006 F-150 4x4, with 107,000 miles, has in intermittent brake light on. I replaced the rear pads, as they were nearly into the rotors. The brake pedal feels fine in all braking conditions. Could the master cylinder still be going bad? Anything else to check?

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.

ll, I changed out the master cylinder on my 2002 F-150, disk brakes front and back w/ ABS. Bleed all the air out and bench bleed the master cylinder. I have good pedal but the brake light will not go out.

We recently purchased a used 2006 Prius. The vehicle has approximately 74K on it now. Well the other day my wife went to leave work and pressed the power button while pressing the brake pedal, and the Master Warning Light and brake warning light both came on. The car would not allow her to shift the car so she tried to turn it off and it wouldn't do that either. After about 5 minutes she finally got the car to turn off, and when she restarted the sequence everything went back to normal and she drove home fine.
We called 2 dealers and they both seem to be confused by the symptoms, but one thought that maybe the battery was old on the transmitter. So thinking that might make sense I replaced the battery with a new one.

I bought a 2006 Sonata V6 3.3L with 137k on it about a month ago. Engine and Trans is great, but I noticed an issue that developed within the past week and a half or so.
I am one to always engage the parking brake when parked, to relieve pressure on the parking paw in the transmission. After about a week of heavy use of the parking brake, I began to hear a slight 'clunk, clunk, clunk' coming from the rear passenger wheel (it actually sounded like something was loose in the trunk, but ruled it out). The 'clunk' sound at first only happened going over rough or bumpy roads, but within the past week or so it's gotten louder and more consistent. It now 'clunks' regardless of speed or road surface.
I used the parking break today for the first time while the car was in motion, and when pulled it sqreached very loud, didn't really stop the car, but the 'clunk' became very loud while the break was pulled - shockingly loud, actually.
A couple of days ago I took the rear passenger tire off while jacked up, and spun the wheel. With neither the parking or regular breaks engaged, the wheel made a 'clunk' sound very similar to that it makes on the road. Took of the Tire/Rim and spun the Rotor, to hear the same sound. Attempted to wiggle the Rotor and found no play at all.
At first, the clunk went away when you pressed the floor board brake pedal, even just a slight bit stopped the noise. Now it doesn't seem to stop it any longer.
My main idea is that the parking brake in the Rotor is the culprit, given that the issues didn't arise until I started using the parking brake - and the fact that brake appears to not work very well. However, my dad tells me he thinks it's a wheel bearing. I don't think it is - as its not making any metal on metal sounds, nor is it very difficult to rotate the Rotor while jacked up.

I just purchased this vehicle from a private owner, and the first day everything seemed fine. After a few days I get all these warning lights - Master Warning (Red Triangle !), VSC, and the Brake Light, plus the NAV screen shows the red car with ! in it. The car seems to run just fine though. I don't notice any performance issues. One thing I did notice when I purchased the vehicle, the previous owner had a batter charger in the trunk before he took it out.
Now I've check the batter using the LAN Monitor and it shows like 12.1 volts when I turned the car on (not started). I decided to give the batter a deep charge overnight (2 amp charge) after disconnecting NEG terminal from car. It cleared the codes for a little while, but then they came back. My ODB II tester shows no codes, only codes I found on the LAN Monitor was for NAVI - 01-e3 sub 00-5. Do I need to replace the 12v Battery?

I have an 08 Sonata that just failed inspection due to the parking brake not holding. With the lever full up the E brake doesn't stop the vehicle at idle.
The rear wheels have disc brakes. How do I adjust the cable to remove the slack. I believe there's a center drum so I suspect there's a star wheel that must be adjusted. If so, which way does the star wheel need to turn, up or down. Is it the same direction on both the left and and right side of the vehicle?

My left parking brake cable seems to stick. The parking brake shoes and springs appear to be fine. I have ordered a new left parking brake cable and need to know how to remove the old cable and feed the new cable to the hand brake lever. Looking for the brake cable removal procedure and diagrams?

My parking brake light came on while driving. The car would coast at a low speed OK, so I think the brake was not on.
This happened in Yellowstone National Park at altitudes above 7,600 ft. and happened 4,000 miles ago and hasn't happened since. Taking the car in for an oil change today and I am going to ask about it.

Which line goes to front brakes and which to rear from the master cylinder?

I had this sad puppy noise coming from my brakes so I have now replaced my brake booster. When doing so I took my old brake master cylinder and put it on my new brake booster. When trying to bench bleed it it only came fluid from the P marked circuit. It came no fluid from "S". I guess it stands for primary and secondary.
I thought it was because I couldn't press the piston hard enough so I installed it in the car so I could use the brake pedal to get more power. But still no fluid from "S". Is the brake master cylinder faulty? The rear discs are unevenly worn.

I replaced my MC cap and gasket less than a year ago with a Dorman replacement and I'm leaking again, already. I don't want this to be an annual thing! Any good quality replacement? Is there any tip or trick to get the gasket to seal better?

I have leased my 2012 prius since April 2012 and about a year ago I began to notice the following noise originating from the master cylinder/ABS unit. The noise happens if I push the pedal firmly to the floor and occasionally during regular braking. The braking system seems to be working fine and regen braking is functional. I am wondering if this noise is a sign of an imminent failure.
Listen to audio recording....

I have a '99 Silverado 250 with a leak between the brake reservoir and the master cyl. Mechanics tell me there is no gasket. How can I get it to stop leaking?

Early 70's Ford truck. The brake MC fluid is filled but not overfilled, and doesn't leak at all when the truck is parked. It can sit there for a month and never leak a drop, parked. But when I drive the truck, even just around the block, then park, and look inside the engine compartment immediately the brake MC is dripping brake fluid. It appears the leaking mode is by the fluid somehow jumping up and coming over the top edge of the MC when the truck is in motion or when the brakes are applied. All my diy'er years of replacing brake master cylinders on Ford Galaxies, VW Rabbits, Corollas, and this truck, I've never seen this kind of weird brake problem before. On this MC design it seems there's sort of a rubber baffle inside the lid of the MC, and that's present and accounted for.

My 2003 Toyota 4 Runner with 104K miles recently started showing a brake light off and on. The brake fluid reservoir was at the minimum level and there was some residue leaking from the bottom near a silver disc. Took it to a mechanic and was told it was most likely the master cylinder leaking brake fluid. Is this normal wear and tear or is it unusual in this vintage vehicle? I do not notice any brake slippage at this point. Should I take this to the dealer and ask why this master cylinder is faulty? I thought Toyotas were long life vehicles?

Whenever I start my 2011 Sonata Turbo after it has been resting overnight, the brake warning light comes on and stays on. It's not immediate?it usually takes five to ten seconds, and whether the emergency brake was on when I started has no effect. Once it goes on, it cannot be shut off without shutting off the car and restarting?at which time it acts normally for the rest of the day. The braking system is fine.
