'95 Toyota camery dash idiot brake light help pls

Idiot light's on; brakes fine; light goes off if electrical connector @ master cylinder disconnected. Toyota tell's me there is a float in the master cylinder that's apparently stuck in the down position intended to warn of low brake fluid.
I topped up brake fluid (down 1/8th ") and float apparently still stuck down ie; circuit still completed & idot light on.
I'm assuming as the disconnected m/c connector turns off the dash light the console hand brake switch is not the issue.

Electrical connection is angled out toward engine bay from connection point on master cylinder. Haven't yet removed brake fluid to see what I can see inside master cylinder; Toyota didn't have a replacement with the built in switch and float to show me what I'm looking for that's stuck.

Probing inside m/c and tapping hasn't freed the float so far.

Any experience with this anyone?

I think there is a screw on the bottom that will allow you to remove the reservoir. Once off you maybe able to clean it out.

Just to throw something out here, this may or may not apply to you, but there is a mechanism on certain cars (the catera for example) that is a part that is ONLY included with the manufacturers brake pads, and it includes the defeat for the idiot brake light.

My father replaced the brakes on his catera with 'generics' not from cadillac that did not include this part, which I believe is the lining warning sensor (stupid that it has to constantly be replaced since removing the pads destroys the part) and ever since then he has the idiot light constantly on.

Just a suggestion, you should consult your dealer/owners manual to check on that

Thanks for the Catera info ..... may apply here also tho the front pads are fine ,,,,gf wondered if the parking brake handle got applied too high ,,,, may pull the console anyhow just to have a look.

Chiltons hardbound '95 - '99 manual makes no mention of this particular master cylinder. Guess I'll call the dealer back and talk to a brake specialist and see what that person know's. Side note; the parts person at the dealer was wonderful going thru everything he had in his manual's and online resources.

Still have to syphon fluid out of the m/c and see what I find.

Thanks again for the help so far

I can say with 100% certainty that you have no electronic sensors on your brake pads - don't waste your time there. My money is still on the float in the master.

Please use the "reply" button instead of starting a new post.

BTW there is no electric pad sensors....your problem as you have already found is the float switch.

thread said closed and wouldn't let me use the reply button .sorry

Toyota service adviser said problem is in the cap .... part's confirmed this isn't correct and asked I give him vin # .car returns tonight and I'll do that + syphoning brake fluid off to see what's 'seeable" inside the m/c

this, as does all else, has an explanation.

Other thought is the float in m/c & console hand brake switch are a loop and disconnecting the wires @ m/c just happens to be a convenient place to break the loop and turn the idiot light off..
Issue might still be in the console hand brake lever switch .... and on we go

You are not dealing with a series circuit (loop).

The float switch has nothing to do with the hand brake switch.

If you PM me your e-mail I can send you the wiring diagram.

Problem solved (for now). Overfilled m/c; idiot light went out; removed extra brake fluid back down to full mark. We'll see if the light stays off.
Email address pls Larry or I'm at XXXXXXX@hotmail.com . I'll take that wiring diagram.
Regards
