Last winter when I did my brake job (unplanned due to a frozen pin) I left the original parking brakes untouched. They are the OE drum in hat style that Ford loves on their full size vehicles and they have received intermittent lubrication but now have almost 130k miles. Figure it would be nice to pull the brakes down to grease and inspect this summer and might as well do the p-brakes while I’m in there.
The OE shoes and most aftermarket shoes are organic but there is at least one semi metallic option. These are really only used as parking brakes and only rarely, way to undersized to expect any use as an emergency brake so I’m not sure semi metrical has ANY benefit here. Thoughts? I’d like the best “grab” from a total stop- so the best coefficient of static friction. What material would offer this?
