Rear Drum Brake Adjustment - 220Sb

Post by dynamike » Mon 19 Jun, 2017 7:03 pm

So I replaced the left rear brake shoe on my 220Sb with that from my 220SEb donor car after the friction pad came off. The replacement sits too tight generating way too much heat and I need to adjust it.

Looking at the top row of the photo below that bolt very much looks like the eccentric bolt used to adjust it mechanically. Though I'm slightly confused as I expected the 220Sb to have the automatic adjustment?


Also, the bottom photo shows the hexagonal bolt holding the brake shoes in place. This is how I found it but shouldn't the thick washer sit on the outside so the inner brake shoe sits right against the pressure spring on the anchor point?

No, the finnie does not have automatic brake shoe adjustment.

Make sure those excentric bolts rotate freely ( but not loosely)
Rotate the excenter so that the shoes are fully in.
Install the drum, with a couple of wheel bolts so it is fully home.
Make sure the hand brake cable is loose.
Then adjust each shoe until it starts to hit. A little bit of drag is fine.
Check your hand brake, should rattle max. 7 notches. Adjust cable if necessary

I can't tell if that washers sits in the correct position, but your brake shoes should be parallel to the backing plate.
