[MBZ] W116 brake warning light blinking
Vehicle is my '79 300SD. Recently, when starting the car, the dashboard brake warning light will blink on and off for about 10 seconds. What does this mean? Pads are not worn, fluid level in the master cylinder reservoir is normal.

One, labeled "BRAKE" is hooked to the parking brake pedal, and the fluid level sensors. The other is hooked to the brake pads. I'm guessing it's a parking brake pedal switch issue, if it's "BRAKE". If it's the other, sometimes the sensor wires can get in the way of the sharp edge of a worn brake rotor (disc), and register false positives. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Which light? The red parking brake warning, or the orange pad wear warning?

That's for the front brake pads. It works by grounding when the pads get worn. Either your pads are worn or one of the sensor wires is shorting out against something on occasion.

I vote for the sensor wires. This has happened to me as well. On Wed, Jan 9, 2019 at 12:53 PM Rick Knoble via Mercedes < mercedes@okiebenz.com> wrote: > > That's for the front brake pads.

Does the owner's manual say anything about the light? I've got bad insulation on the wear sensor wires for the front pads on my 87 300TD, but the light blinks intermittently during each drive, for the duration of the drive. -- Max Dillon Charleston SC On January 9, 2019 11:54:52 AM EST, Allan Streib via Mercedes wrote: >Vehicle is my '79 300SD. > >Recently, when starting the car, the dashboard brake warning light will >blink on and off for about 10 seconds.

Re: [MBZ] W116 brake warning light blinking
I've had insulation on the cable _to_ the sensor sockets start to fall apart, at the wheel end. You just have to get in there and take a good look at everything. I think you can unplug them in the engine compartment, see if that makes a positive difference. -- Jim ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

I've had the fluid level sensors go wacky. I unplugged em and the "problem" went away.

Sadly I don't have an owner's manual for this car. I'll check the pad sensors/wiring for any obvious damage. The blinking on mine is only at startup (but not every time), and stops after about 10 seconds.
