anyone know how to adjust the parking brake to make it tighter, goes almost to floor and barely holds. I just installed new shoes and wonder if there is an overall adjustment, I'd like to avoid revoving the wheels and drum/disks to rotate the expander nuts.

Hope this might help

just tightened up my parking brake on my C230 three weekends back

on my car the parking brake is activated by a drum design inside the brake disc hub

when the wheel/tire is taken off and with proper lighting - halogen work lamp or small flashlight with pinpoint focus - you look through the upper lug nut holes and by moving the disc from around 11 o'clock over to 2 o'clock you will find a little gear wheel with the teeth facing outwards - be sure not to confuse it with the larger springs which have a similar apperance - and by rotating the teeth with the blade of a flat blade srewdriver the brake should tighten up in

on my car the driver side gear was rotated downwards and in about seven pivots with the screwdriver tightened up, then I backed off to just when it started to free wheel. on the passenger side the gear tightens by being moved in the opposite direction - upwards

I think the desired is to have full activation of the parking brake in ten clicks of the parking brake pedal
