Car Forum / BMW Cars / January 2007E34 540i sticky brake pedal
1994 540i automatic. Brake pedal sticks when pressed, thus leaving the brake lights on. I can pull it back up with my foot and the lights go out. Even though pedal sticks, it doesn't feel as if the brakes themselves are sticking. Is this a simple thing like needing to lube the brake pedal mechanism, or something else? Thoughts? Thanks. > 1994 540i automatic. Brake pedal sticks when pressed, thus leaving the > brake lights on.

Is the car left or right hand drive? If it's a right hand drive car I might know why......

The damn things are designed as LHD and the master cylinder is also on the lefthand side of the engine bay. It's 'remotely' operated by a linkage rod running across the bulkhead from the pdel on the right side of the vehicle. The pivots for this rod often get overlooked when it comes to lubrication maintenance. A few drop od oil and all will be well. Of course if it is a LHD vehicle, all bets are off. JB It is left-hand drive. > >> brake lights on. I can pull it back up with my foot and the lights go > >> out.

Oh bollocks. Scrap my idea then. I'd still have a look at the pedal linkages and give them a lube though. JB Problem has gotten worse over last 24 hours. Now I have to press the pedal about as hard as I can to engage the brakes (and they stop the car immediately - not smooth at all). Then I have to pull the pedal back as hard as I can to disengage the brakes. As you can imagine, it is almost impossible to drive in this condition. I tried to look at it from the cabin but can't figure out how to get the plastic cover to get a good look at it. Frustrating!!!! > > It is left-hand drive. > [quoted text clipped - 21 lines] > > JB > Problem has gotten worse over last 24 hours.

This is starting to sound more like a master cylinder or servo fault. I'd get this looked at professionally if you feel you haven't got the experience. No second chances with brake failure.

Thanks. sounds to me like you have a sticking caliper. Also check the condition of your master cylinder, may be time for a rebuild/ replacement. Thanks for the feedback and suggestions, everyone. Turns out it wasn't the master cylinder, calipers or pedal... my mechanic took out a "joint" somewhere in the brake line, cleaned & lubed it, and now the car brakes like a dream. Smoother than it ever has since I've owned it. On Jan 29, 9:01 am, greg1...@hotmail.com wrote: > > 1994540iautomatic. Brake pedal sticks when pressed, thus leaving the > > brake lights on.

There ought to be a rather substantial spring that returns the pedal to the top when you remove your foot. > 1994 540i automatic. Brake pedal sticks when pressed, thus leaving the > brake lights on.
