On my 2007 E350 SMB the parking brake pedal goes to the metal and it still slips on a grade. My mechanic says the adjustment at the drum is maxed out. How can I shorten the cable a bit? This rig needs it as my driveway is inclined. Next up is a new cable, perhaps.
Yup, it happens pretty easily. Last spring while on a rally, someone came on the radio and said "someone's parking brake is on", he could smell it. Sure enough, it was me. Even with new shoes and properly adjusted they still have so little effect that it's easy to miss the fact they are still on.
