help, unable to depress brake padals..

[tatsit]

this morning when i tried to start my engine, i found myself unable to depress the brake padals, not even abit and was unable to start the engine. i went to inspect the brake pads but found nothing obstructing so i used more strength to step on it and managed to start the engine and started pumping the brakes.

it went back to normal after i moved off. is there some kind of problem with my brakes?

check your air-tubes in the engine bay....probably something wrong with the vacuum

It's a common problem for E90 320i. If your car still under warranty, bring back to PML to fix.

There's a few threads on this... you can do a search on the forum

Re: help, unable to depress brake padals..

9 out of 10 times, the vacuum pump on the engine has failed and this has caused engine oil to seep into the vacuum lines running to your brake servo. The oil screws up your 1way valve (to keep some vacuum in the tank even is the engine is off) and if left untreated, the oil goes into the the booster and screws that up too....brake booster really not cheap.

1 sure way of testing your brake system ( for valvetronic cars) is to find a nice EMPTY hill. As you drive downwards, depress the brake pedal and release slightly so that the pedal is still engaged and your foot is still touching. (like press 3cm and release 1cm). Repeat this procedure as many times as your can until the pedal firms up and your foot pressure just cannot seem to slow the car down. If you cannot manage more than 5 strokes, there is a problem with the pump, valve or brake booster.

Good Luck.... remember empty road..

Will this be pick-up by the diagnosis system?
