Cluth and brake pedals interfering with each other?

jrougeux · 01-01-2009, 05:56 PM

The clutch and brake pedals seem to be rubbing against each other on my E90 with 32K miles. For example, if the car is in neutral and I press the brake pedal, there is some very firm and sudden resistance once the brake pedal is depressed about an inch. It feels like the pedal is caught on something. If I push especially hard, the "catch" gives way and the brake can be depressed all the way. However, if I push in the clutch before braking, the problem doesn't exist, and the brake pedal action is smooth.

In addition, when releasing the clutch pedal, the pedal "catches" on something about an inch or so before being released all the way. This occurs whether I am braking or not. The pedals are not interfering with each other down where my feet press against them; the interference seems to be occurring in the pedal linkage somewhere.

Any ideas? Can the pedals be adjusted to fix this problem?

a while ago I had the problem which turned out to be that the top edge of my carpet is getting rubbed when the pedal travels, are you sure that's not what it is?

It's definitely not the floor mat, but the permanent carpet extends beyond where I can see. Was your problem caused by the floor mat or the permanent carpet?

The brake issue could be the start-off assistant you are feeling. If you release the brake pedal when you feel the resistance do the brakes stay applied for a about a second?

It's not the start assist (or hill assist). The pedals catch against each other during forward motion as well (basically between every gear shift).

Maybe you have really wide feet

Have a look under that dash panel maybe somethig like a loose wire is catching on the pedal arm.

I wish it was wide feet or a loose wire. Unfortunately it's not.

Could it be something mechanical?

Could it be something hydraulic related? I don't know enough about the cars design however maybe there is air in the line if they share the same master / slave cylinder.

Other than that I'm stumped, next suggestion was to take it to the dealer / mechanic.
