1984 300D Rear shoe brake replacement adjustment.

Submitted by Rafe E. Phipps on 19 July 2010 - 5:38am.

Just replaced and tryed adjusting rear brake shoe assembly with new rotors...Now, the car does not back up or feels like it is rolling up onto something. Not sure if I adjusted the star gear properly. I know there is a balance, but this is getting frustrating. The E-Brake pedal inside the car does not get enough resistant/stiff when pedal is pushed down. It releases fine/quick.

 Rafe, here are some things to check first:

  • Could you have rusty cables that are sticking - check to make sure cables are moving freely inside housings
  • Check to make sure shoes did not come off track and are binding inside drum
  • Lug bolts correct.  If too long that can hit the emergency brake and bind

You need to be able to spin the wheel while adjusting the star nut. Lock it up tight and then back off until wheel just starts to spin freely. You can do one side at a time.  Hope that helps, Kent

Shoe and cable re-adjustment

Last night got the rear end up, rotors and calipers off. Springs looked to be intact...readjusted shoes and turned the wheel with a slight resistance(not complete revolutions). Got underneath and the cable assembly is intact and adjusted the bolt while a friend put the brake on and off. Thought it was a success until I took a test drive and heard a click-click-click noise and pulled into the garage and a loud thump sound ended it with frustration/uncertainty...called it quits for the night.
One thing I may have not done is actually spun the wheel in complete revolutions rather than slight turns. Maybe a broken spring or two? Lug-Bolts too long? (28.7mm thread and space length) Wrong rotors? The Wagner BD61925 fit good, so are they interchangable with the front? Got them cheap at a dealership a few years ago. Could you cross reference them with Meyle?

Thanks Again,

Rotors placement.

Few years back when I got these Wagner rotors, had a friend say he could do front brake work, so put my trust there. Come to find out after looking in the garage, still had the old front rotors in a box. We put the back rotors on the front, and this, left me with these front rotors to put on back...now it all makes sense. I will swap rotors and see if this helps with the clicking noise and so forth...Funny, how they fit good and align with the calipers and hub. Don't shoot, I'm only a guitar/piano player!!
