e-brake question

[Fred Munro]

Hi Konstantin;

Before you pull the caliper, try driving the cam in with a dead-blow hammer.
I've had to use a hammer at times to move the cam back in until the lube
works it's way down the shaft. You don't need to bash it - a sharp tap
should do the trick. Leaving the cam sitting out while you played tennis may
have resulted in it "sticking" in the out position - plus the car probably
feels you don't love it anymore, so be prepared for trouble :o)
