When I haven't used my 1998 conversion van for a few days, my rear brake shoes are grabby and lock up the drums until they get cleaned off of rust after a short drive. Has anyone got a recommendation on replacement rear shoes that fixed that issue?

 

Well no help to offer, only condolences that you are not alone. My 88 does the same thing. My mothers 78 van does the same thing after sitting.

My guess is that whie sitting the drums oxidize just slightly. I don't know how much driving habit might have to do with it but, I very seldom make hard stops. I tend to coast to a light stop. I am not sure if that makes a difference on how much of the old oxidation is worn off inside the drum or not compared to someone who run right up behind others and then slams on the brakes.

Perhaps the actual brake pad material affects this to

 

Typical for drum brakes. You really can't avoid that when humidity is high or temps are freezing. Nearly every truck I drove and my current van have this issue, even after sitting just overnight. First time tapping on the brake and the rear tries to lock up. I always tap the brake slightly on the first 20yrds in the morning, helps most of the times.

 

seems there is a tsb about rear drum brake pads on the older e150s about needing to use a Motorcraft pad to keep them from grabbing but i dont remember the details..

 

My 97 250 does it too.

 

this is for an F series but again i seem to remember a TSB about this for the econolines

ISSUE
A grabbing condition from the rear brakes during the first few brake applications after extended humidity exposure may occur on some vehicles. This
may be caused by a rear brake lining that is sensitive to humidity exposure.
ACTION
Replace rear brake linings with revised Rear Shoe Brake Kit (F85Z-2200-AA). Refer to the appropriate model year F-150 Workshop Manual, Section
206-02 for service details.
