I have this ongoing extremely annoying problem with my rear shoes. After numerous trips to one of my mechs, he is stumped and said he cant help me out anymore but he says my shoes are overtightening over time for some reason. And when it overtightens, it causes extra drag and this super annoying sqeaking sound when braking and eventually (if i let it go and get worse), will do it when NOT braking.
Ok I will have new set of high quality shoes, new drums, new wheel cylinders, new spring kit, the high points of the backing plate where it rubs against the shoes, lubed with polymer grease. And over time, the shoes over tighten automatically. This can be anywhere from 3 weeks to 2 or 3 months.
Last time i had this all replaced was last fall and i mean everything on the back end was replaced, even the left auto adjuster cause they thought it was the auto adjustor.
Now all my mechs have tried diagnosing this but none can figure it out after numerous trips. But theres some obvious key points that weve noticed and almost certain are huge factors in whats causing this.
1) This problem is on and off. Dragging noise can be gone for 2 months but all of a sudden come back the next day and last the next 3 months and progressively get worse in noise.
2) Theyve all spun the back wheels with the rear jacked up. Even before or after the brake jobs, both wheels have a small high point that can be felt when spinning. Its just a small high point but during this high point, you can feel the wheel dragging noticably more than during the rest of the wheel spin. Exactly when the wheel is spun and goes through this high point is where the drag and noise occurs. Everytime.
3) Whenever you replace the shoes or readjust them, the noise is gone but will eventually come back.
When i had the shoes and everything replaced last fall, they would basically set the adjuster to the point where it has very very litte drag when spinning. Weve even tried backing the shoes all the way to its loosest setting and just have it auto adjust on its own over time. Still it overtightens over time causing the drag. And I prefer not to have the shoes backed all the way off cause then the stopping power on the rear is very minimul and not very effective.
Everytime i had them adjusted i would back up going about 20km/h and hit the brakes firmly about 4 or 5 times.
We cannot, for the love of god, figure out why there is a high point in both wheels cause obviously there shouldnt be. Replaced literally everything on the back end even including ebrake cables and nothing can get rid of the high point.
Cause im almost certain, get rid of the high points and extra drag and noise is gone.
