Ford F-150 (2004-2008) :: How To Replace Brake Fluid Level Sensor
Jun 10, 2014
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?

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 ....

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.

I bought an 04 F150 SCrew 5.4 3V a while back. The power steering fluid level keeps dropping. I have topped off the power steering reservoir at least 3 times in the last month and a half.
What's got me baffled is I can't find evidence of a leak anywhere. The hoses, the pump, or on the belt. I've crawled over & under it. I can't find anything anywhere.

I just had a remote start installed with a turbo timer that works off of the parking brake being engaged. No matter how hard I press it the light does not go on, however when the installer probed the sensor to ground it, it worked fine.What part this is that needs to be replaced. The stealership quoted me at 200 something for a whole parking brake assembly.

The 2003 Ex. Made it back home last week after a couple years at college. .. registration sticker expired last June! Drivers side mirror "taped" on. Rear bumper cover torn in half w/ a few screws holding it on.
Busted out foglight & small tear in bumper cover above it.
Brake light on - noticed fluid low & cap not seated correctly. One of the tabs that hold the cap in place is broken... new reservoir under $20 at rockauto. Looking for a write up or better to replace entire master cylinder?

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.

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.

The 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.

I purchased a 2008 Prius with 117,000 miles lat month. I took it to a friend's house recently. When he was looking at the car, he told me that my coolant level is low and put some coolant in the reservoir. The next day when I was driving the car I was hearing a rattling sound every time I pressed on brakes. I could not figure out what could be the reason. The sound went away after couple of days. Today I was going through the manual and noticed the place where my friend put coolant in is actually brake fluid reservoir. It looks a lot like coolant reservoir of my other car. So now I am wondering what could happen if coolant goes into brake fluid reservoir. Will it harm my brakes? It has been about 2 weeks since that incident happened.

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.

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.

The passenger side door of my 08 Accent Hatchback got frozen after cold icy rainy night. I forced it open after few try, and found the rubber seal underneath the door was ripped off (ice in it). I put it back in, but after turn the engine on, the airbag light is on.
After some google, I think I damaged or disconnected the sensor in the passenger side door panel. How to fix it?

This last week my brake fluid light comes on my 2006 Ram 1500 but my fluid level in the reservoir is at max..fluid is a yellowish color when I look at it out of reservoir (looks darker in the reservoir).
If I unplug the sensor to the reservoir, the light still stays on which puzzled me, but I'm not honestly sure what I'm hoping to see happen. I am no positive if I'm due for a brake job, but the pads still looked to be good to me (not sure if that could trip the sensor). Where to start?

I started to notice a slight whine when I turn the wheel. My fluid is at low but it's pretty dark and I'm not sure if it was ever changed or when. I have 100k miles. What fluid should I use?

How hard are they to put on, and who makes the best one? I was told about hell bent steel, but I am not sure? I got an 04 Ford F150 looking to level it out...

2004 F150 Supercrew 4x4 Right now I have a broken roller cup on my rear U-joint. So I bought a new U-joint from the Ford dealer. When I pulled the driveshaft out I couldn't tell how to replace the U-joint. There are no E-clips to remove from the yoke/driveshaft ears. There are solid round "O" shaped clips that looked to be pressed in or something.
I've talked to the Ford dealer as well as a few other local mechanics and they haven't seen this setup before. So I didn't get any assistance there. It seems like my only option is to replace the whole pinion yoke, driveshaft, and U-joint together. Which sucks because this is just a frikkin' U-joint that needs replaced. That's it. I guess what I'm asking is, is there a way to work on this non-serviceable U-joint?

Tried searching, but I couldn't find any good write-ups on how to replace a front CV axle. The boot on mine is ripped and spraying grease so I figure I should just replace the whole axle while I'm in there. In a previous post, I also found out that replacing the CV axle (joint?) is easier than replacing just the boot.

156,000 miles, I've been pulling a 21ft bass boat in the summer for years with no issues. Now on hot days (over 78 degrees) it is over heating. Can't use AC and need to slow down to 60 mph in-order to cool her down. Never have flushed the radiator but I'm wondering if getting it flushed is a waste of time and if I should just proceed to replacing the radiator? For a couple of years now I can hear a roaring sound (like a jet engine) on really hot days, when I start out driving. Could this be a cooling fan? Seems like the power is restricted during these times. Really need to increase throttle to get going?

Alright, I, like alot of people with these trucks have the rust under their fuel doors from what ive seen and heard is the fuel neck filler plastic vibrating and rubbing, wearing throught the paint allowing water and fuel drips in and getting under the paint.
Well i keep touching up my spots but i have to do it twice a year and it just keeps getting worse, so i decided to go a bit further and clean it, touch it up, and protect it. This is a low $ job. Its not perfect but it is definately better than rust and from a couple feet back you can barely notice it, and hopefully this will be the last time i have to touch it up.
