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?
View 4 RepliesSo 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.
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.
View 6 RepliesWe 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 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?
The brake light on my 04 has come on twice the past week. The brakes are working fine, no problems. When I turn the truck off, then restart, the light goes out. Just had the front rotors changed.
View 6 RepliesAs the title states, my brake light on the dash keeps on coming on intermittently. I can't figure it out. Fluid level is fine, and I added more just to be sure. Pads and rotors all got replaced within the last 9 months. I don't see any chafed or broken wires to the wheel/abs sensors. I don't know where else to look
Also when the light comes on the pads on the rear passenger side seem to drag a little bit. I can't feel it, but I can hear it just slightly.
Just purchased a 2003 GX470 with 160k and after the low brake fluid light came on I noticed the master cylinder had a leak. After removing the cover it appears the fluid has leaked for quite some time as the paint has started pealing from the frame. The brakes however appear to be working correctly. Upon purchase the front calipers were seized and I replaced both front calipers.
After having someone depress the brake pedal while I watched, the fluid leaks from the end of the master cylinder each time pedal is pressed in.
After doing some research it appears there is a rebuild kit for the master cylinder.
I recently bought a 2004 GX 470 with 89k miles. My dad did the 90k service like a champ and it runs very smoothly. However, I have recently noticed what I believe to be the brake master cylinder, which on a regular basis, has to keep compressing for about 4-6 seconds even while driving. We filled the fluid and it seemed to stop as I was pumping the brakes to test. But the next day it started again and the fluid is still at MAX level.
View 4 RepliesIntermittently, the parking brake/ABS light comes on with no pattern I can put my finger on. Some times its on when I start it and stays on the entire time I drive it. Some times its off when I start it and then comes on while I'm driving it. This morning I took it by Advance auto and had them check for codes while the light was on: C1342 - ABS control module. I can't find a lot of information about this code or what can be done to fix it other than taking it to a dealer. Any alternative solution, perhaps re-seating the connectors to the module - and where the heck is the module and what does it look like?
View 1 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 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?
View 9 RepliesEarly 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.
View 17 Replies...Is there anything special that needs to be done for brake bleeding after putting in a new master cylinder? I decided today to flush my system with my vacuum bleeder and now my pedal slowly falls to the floor at a light...No problems in a panic stop or otherwise, just falls to the floor slowly when braking...no leaks, so I'm assuming a master cylinder is an order....
View 14 RepliesWhy the brake lines have 2 or 3 coils in them near the master cylinder? Makes it a real pain to work on anything down in that area. Always snags ratchets and stuff...
My brother and I were discussing it the other nite, and the conclusion we came up with was, the first guy ever who was installing a brake system had tubing that was a couple feet too long, and couldn't find a tubing cutter, so he coiled them up.
Then the next guy saw that and figured "hmm, so THAT'S how it's done", and so on... Kinda like the story about the lady who always cut off both ends of her ham before she put it in the broiler..
My 2006 F150 was purchased by me in early 2009 with about 28,000 miles on it. It's an XLT crew cab 4X4 with the 5.4. Stock except for a leveling kit and an aftermarket head unit. It currently has about 59,000 miles and has been babied since I purchased it. About 3 years ago I started noting some issues:
A. Oil pressure dummy gauge is all over the place. Some times it will show no oil pressure. Other times it is all the way to the highest mark. Other times the needle has gone 180 degrees past where normal is and is actualy pointing straight down towards the floor.
B. Recently my alternator dummy gauge has started doing the same thing as my oil pressure gauge.
C. The backlight behind my odometer works intermittently, but mostly not at all.
D. My dome light will flicker when first turned on. It doesn't matter which door is opened or if the override switch it turned on. It takes several seconds to come on and will flicker like there is a poor connection somewhere, but stays on once its on.
E. Blower fan will occasionally stop blowing. Once the climate control switch is turned to off, then back to on it resumes working. This doesn't happen often, but does occasionally.
Fortunately, the truck has not left me stranded and I want to keep it that way. We are getting ready to sale my wife's Toyota and this will become her daily driver. I want to take care of any issues before she starts driving it. Are these all separate issues or is there one common issue which could be causing them all?
I tried to replace my brake master cylinder today but wasn't able to because of a plug
It's the black plug on the drivers side, the connector is upside down so I can't see how to unplug it I tried for an hour then got too frustrated I had to come inside
My Haynes manual says "unplug" obviously
I was driving down the highway today and the brakes light (!), vsc, and master red triangle warning lights came on, along with a car with an ! in it on the main display screen. There is no noticeable difference in noise, mpg, or breaking performance. From reading through previous forums a bad 12v battery seems to be a common problem. Mine was replaced ~8 months ago. About 2 weeks ago the serpentine belt snapped and the car was drove ~2 miles to my home where I replaced it along with the bad water pump and also the thermostat. Could that have caused my current problem. 130k miles on the car...

View 2 Replies1987 F-350 460 Auto Trans. Brake Pedal slowly going to the floor. Stopped at a red light yesterday on a slight down hill and I noticed the brake pedal slowly going to the floor. I had to put the truck in Park to avoid bumping into the car in front of me. I checked brake fluid level and still at the full level, check rims for brake fluid leak from brake cylinder, none. Could my master cyclinder need rebuilding or is my vacume diaphragm going. Not sure thats what its called.
