Brake Warning Lights

[palerider94]

My brake warning lights have recently come on in my 1970 power drum stang. Seemed to pop up when I got a vacuum leak from changing carb gasket. Fixed the leak but lights stayed on. Brakes are fine in car. Is htere a way to reset it. I would be okay with disconnecting altogether if I new where the switch was - any help would be appreciated. thanks

switch is on the porportioning valve. Right off the master cyl where all the brake lines go. Its a plug into the prop valve. Does the light come on when you trun the key to acc. or just when the eng is running??

Both - when you turn igntion on and car is running.

Your brakes are not Fine..... that light tells you there is an imbalance in the line pressure to the front or rear brakes.

it needs to be recentered to make the light go out.

Disconnecting it is just fooling yourself........and indangering others.

Thanks - I found some posts on recentering. I did have a leak in back awhile ago that I fixed. Not sure why now it would cause a problem. Seemed kind of a coincidence that it showed up same time I was lost vacuum due to leak in carb gasket. Anyway appreciate your advice even if it was in stern tone. You been right on the money so far..

Sorry for the tone.......
But too many people just disconnect the light because they can't get it to go out.
Then when they have to do a *Panic Stop* wonder why the rear end trys to pass them.

Ps, the brakes are prob getting proper vacume to the booster now and upped the line pressure.

You are good!! Changed the grommet to power booster - old one kept popping off and was probably leaking. Appreciate the advice. My goal is to fix this car right - just get's little frustrating some time..
