"BRAKE" Dash Light On

So, yet another issue with the Compass... I shouldn't be surprised every time something happens to this engineering marvel...

Title explains it. While I'm driving, the e-brake light remains on. The lever is all the way down and the light flashes when I pull the e-brake up in gear.

What are some things to check for this? Never seen this before...

Have you checked the brake fluid level yet?

Yes, sorry. I forgot to mention that was one of the first things I checked.

you have a 07 compass with 110, 000 mile on it. when was the last time the brake fluid was changed or ever, there is a float that can stick as well as your e-brake switch. with that many mile I suspect you have water contamination in the fluid, have it flushed. at the same time inspect the caliper guide/slide pins and drams for condition.

Thanks for the tips. I will try and flush the brakes this weekend. I've been meaning to do it. How would this cause my brake light to be on even if the fluid is old?

As for the e-brake switch, where is that located? Do I have to remove the center console to get to it?

I am new to the compass since i only had it for the last three months and have not come up with a service manual as yet, not needing it right now. that being seed I have worked on hundreds of brake system from aircraft to cars and trucks and all work the same way.
so the location of the e-brake switch I assume that its down by the e-brake handle
got this off of rockauto., not much to it.

as far as the old fluid turning on the brake light in it's self will not, but contamination can mess with the sensors, float.

before you replace switches I would test them, and I would do a inspection of all my brake for function and check all hydraulic lines for seepage, frozen adjuster if you have drums, to name a few.

If you find your problem let all of us know for your information will help others

UPDATE:

Flushed brake system as well as I could today. Started with the back calipers and started pumping brake fluid out of the lines (while keeping the master cylinder topped up with DOT 3) until it was clear in the tube. Didn't see a lot of air in there. Just a few small bubbles here and there.

Brake light is still on. My next place to look is the e-brake switch.

UPDATE:

I replaced the brake fluid level sensor. Only about $4. Still have the light on the dash.

The only other easy fix I can visit is the switch under the e-brake lever. I'll be getting that later.

SOLVED:

Well... as I was trying to solve my windshield wiper pump issue here:
http://www.myjeepcompass.com/forums/...ctivating.html

I simultaneously solved my brake light issue. Since I was not getting current in the wiper pump connector I traced the two wires (PITA - had to rip some wire tape off in multiple places to keep testing Ohms) all the way back to a connection near the TIPM - which I just recently replaced to fix a headlight issue. As I looked down I saw that I had forgot to plug in one of the connectors in the bottom of the TIPM... OF WHICH THE WIPER PUMP WIRES BELONG TO.

ICER YOU'RE AN IDIOT!

I plugged it in, BAM. Wiper pump works like a charm. As I was sitting there inside the Compass cursing myself I noticed the brake light on my dash went off as well! I have no idea why because it was on before I replaced the TIPM so the unplugged connector couldn't be the culprit... or could it? I'm not 100% certain the brake light had any relation to this connector I plugged in... Maybe with me moving wires around down there I removed a short? Maybe the brake light will come back on... Or just maybe it DID have to do with that TIPM connections. Oh well...

I also discovered why my back windshield washer wasn't squirting like it should. If you open the back door and look up at the base where the hinges are connected, you'll see 5 rubber circular grommets. Pop those out and remove the 4 nuts and undo the plastic expanding fastener by pinching/pushing it towards the front of the vehicle. This pops off the spoiler and will get you access to your rear windshield wiper hose of which has a plastic connector joining the two sections of the hose. Mine was snapped in half - so fluid was getting back there, but it was just leaking down the back window. Why these two sections of hose couldn't just be one unit is beyond me. Designed to fail if you ask me... Anyway, I'm lazy and didn't want to wait so I JB Welded it back together.

If you have any questions about any of my troubleshooting or any of the parts I installed, let me know! That brake fluid level sensor seems like it's impossible to install, but it's actually really easy.

Goodnight!

Glad to hear that you figured it out ! Sometimes it's just something simple that we just lapse and forget about, I know I've done it before in other vehicles. JB weld should probably fix it permanently, that stuffs crazy :|

You're right it should, but I hung it up to dry too soon and gravity pulled it apart. Found it lying on the ground this morning. I can't find the part on RockAuto, so off to Home Depot to find something that will work - possibly a metal connector.

This message is for icer22x. Can you please tell me how you were able to change brake fluid level sensor? I have manuals on the location, it just not tell me how to access it. I know that I can't reach it from the top. Any help would be appreciated.
Thanks in advance

It is located on the bottom of the master cylinder reservoir. If I recall correctly (it's been over a year since I changed mine), all you have to do is push a tab down and pull it out. It is hard to do because it's so tight underneath the reservoir. I think I removed some things to get better access to it. Let me know if you need anything else.

Thank you very much for your response. Could you by chance, have removed the panel on the drivers side wheel well? It look like it could be a way in. I didn't want to take the time to pull it apart, only to finding that there wasn't any access there.
Thanks again
Steve

No I definitely didn't do that. I think at most I removed the air intake unit (two twist screws located near front) and the large air intake tube (metal screw clamp IIRC). Just whatever that was easy to remove and got me better access to the underside of the master cylinder reservoir I removed.

Hi to all. I found a video clip today on YouTube that shows how to remove the sensor. The sensor pulls straight out of the master cylinder towards the passenger side of the car. You may need a screwdriver to pry it a little, but it came right out. It did not fix the emergency brake light issue that I have been chasing for years but that's how that's done.
