Just wondering if anyone could help with a problem on a friends kombi. Its a 2lt twin carb motor all standard and the motor cuts out when you push hard down on brake pedal so where do i look to fix the problem.
Any help would be great.

break booster sounds like there is a bad leak in the vacume line
and make sure there is not a ddead short in the break line 4 the stop lights

Fixed the problem thanks by replacing the front vacume hoses (the old ones were a bit thin and brittle).
Thanks once again
Cheers Rick
